@DadHav Nice video mate, really nice elegant design. I've made a small prototype generator back engineered from brushless motors. It works quite well. One question: how come you've not used laminations of electrical steel for the stator?
Hey Mate. Thanks for the compliment. Actually the stators are laminations, but sometimes it's a little hard to tell. Sometimes I take a few thousandths off the outside diameter to ensure eccentricity. At that time I polish the outside a little bit.
I'm not sure what you are asking. There is three batteries in series. The windings are three phase and I terminate the phases in the usual way either Star or Delta.
Your English would be better than my Italian. I saw some parallel path motors but I couldn't find anything to describe what was going on. I know one thing for sure, the principles don't seem to be similar. Man. Those things are loud.
@DadHav the video is in Italian, I do not know if you'll understand, however, the operation is simple ... is based on the imbalance of a magnetic field of two parallel magnets that are concatenated into a magnetic iron core. to unbalance the field using two coils in series with a small energy can move a very large field. if you want a design you do it but there is also the Internet if you search.
Hello. Yes, I saw some of the more simple videos and understood what they where doing, but it wasn't very clear on the large round ones. I will find some information outside YouTube. The concept looks interesting but at first glance it looks and sounds inefficient. I appreciate you drawing my attention to the motor, it looks interesting. If I decide to do anything with it I'll give you an update.
@DadHav Go to see the comparative, parallel paths VS motor induction motor. is stronger than the double, have patented the engine step by step, however, go on youtube to look like this: Test Comparativo MK12 vs Asincrono.avi
how i can get the magnet ! and how to set the wihers ...did you make you'r oun command or used a old one from a airplane ...the thing is i'm trying to make a airplane and can't have good motors to make it fly also i do every thing on my own ^^ thx for helping ....sorry for my english
I was thinking of building something like that because I have all the machinery you do and I know a lot about electronics, but when I saw in your video all the work it needs to be done concentrated and the craftmanship involved, I think I will just buy one when I 'll need it...
@DadHav There are so much things I want to learn how to do, unfortunately there is so little time... But there is no feeling like the one when testing a new prototype machine build by you from scrach...
When I made the video I only had 10 minutes to use. That made it a little difficult to slow down and explain things. I didn't expect the video to be as popular as it turned out. I will probably make another video when I get caught up on things. The motor is basically a 25-15-950KV motor if you are familiar with the terms. If you have any specific questions, I'd be happy to answer them.
The motor in the video is actually pretty small and meant to fly a park flier size airplane. I would estimate the motor to have somewhere between 500-600 grams torque if it was running at a comfortable amperage of 15-18 amps with a 9 inch propeller. Just a guess but it will take the plane I have it in vertical with not trouble. I thing the plane is a little over 1.5 Lbs.
Thanks. I had my share of CNC retrofits, mold design and programing. I'll take turning a crank on a gray Bridgeport any old day. I don't think anyone will be able to stop the skills from this part of the trade from slipping away. Maybe some of these videos will stay around for a while to remind people of how things where done a long time ago.

Hey Thanks. Having someone else recognize my efforts always makes me feel good. Sometimes I get carried away with the pride of craftsmanship thing but I don't know any other way.
That depends. There are some pretty good motors on the market today. The really good ones cost enough money that I'd rather make my own, so I really haven't had a chance to make the comparison. I would put my motors up against the finest though and probably fair pretty good. I pack the copper in probably more compact than retail motors and have a closer air gap between magnets and stator than conventional. Special thin lamination stators also help.
Thanks. I appreciate that. Actually everything I have here would be considered an easy job by the people who taught me. Maybe some time I'll get around to something really difficult. One of my favorites was cutting threads on the milling machine before it was done by CNC. The trick was a rotary table with threads instead of bearing in the center. It would move up and with a cam and slide to the side. Tipped head, special cutter and you can cut taper pipe threads.

@DadHav Idiot behind the wheel of daddys car... think because they are in a fast car that they know how to drive!! But nice build man. You should sell these on ebay
I wish to go full size with two big coils making the one do the job and the other charging up with the re-looping waste power and some 60 kg lift force on my magnets.
Maybe i don't need that much, but i have allready ordered hah and my fantasy is just too frivolous ^^
Hey Nick. I wish I could make motors at a price people could afford, but I just have so much time in them that it wouldn't even be practical to think about. Thanks for your interest though.
G'Day mate, Im trying to find the stator segments big enough to build a decent sized brushless motor/generator, could you please help me out, kind regards david.
Almost any DC motor with permanent magnets can be converted. Larger stators are found in some ceiling fans, the flat radiator fan motors, Smart Drive washing machine motors, I use some large size office printer motors. You can find them on E-Bay by typing a search for Printer Mains Motors. I just heard of an excellent choice: A 48 volt hub motor for an electric bicycle makes a good generator that doesn't need to many RPM's
There are kits and parts available for making the R/C size motors. An excellent site is Inov8tive Engineering. This is a Scorpion motor site ran by a great person to deal with. If you go on the LRK TorqueMax Group on Yahoo you can find everything you need to know about building a motor as well as links to suppliers.
I was a bit confused with the winding method. You method shows a side by side winding where as i have seen some motors having windings on opposite poles.
can you elaborate the same. my email is lunarhemal@gmail.com
Yes, I enjoy making motors. At one time they where better than most from the store. There is still an advantage
to making them if you have a special need. As an example I have one in a vintage Aquila Grande sail plane. I needed one to be moved back in the fuselage for both balance and fit, so I simply made a magnesium bearing holder / motor mount that put the rotor where I needed it. By the way the plane weighs 4 pounds and climbs out at about 60 degrees.
Manufacturing technology should be a required course in all American high school curricula. Perhaps this will give some meaning and appreciation to the term "made in USA."
Ha, That's an interesting thought. I hate to say it but some day there may be a short segment in you're History Class on the Masters that worked in an aera of precision hand machining.
The machining shown here is truly superlative! Every CNC machinist really needs to learn the old manual techniques shown here first in order to understand proper feed/speed/horsepower calculations, tool path and more. I witnessed more than one young hotshot in engineering school who could not understand why you cannot cut stainless steel at the same speeds speed as aluminum. This author shows how to properly think ahead and plan ahead, before putting tool to metal. GMP followed properly.
When I started the trade. We had what was called a buzz box. This was a stylus that went on the spindle of the milling machine and was wired to a speaker with a buzzer circuit. We would make a plaster mold of what we wanted to cut and paint it with a carbon base material. You turn the mill into a tracer this way. You can move XYX, touch the model until you buzz while the end mill is cutting in the steel. I know tons of old tricks like this.
Yes, I'm a member there, but don't spend a lot of time there. The small SX-3 milling machine I use is a popular choice on their forum for conversion to CNC. You're right it is a quality forum with talented people. I have a strong background in CNC and was involved with retrofitting some large machines but my love is in the hand machining era. It saddens me to see it slowly becoming a forgotten art.
@DadHav It seems the majority of people on homemodelenginemachinist feel that cnc is cheating, so you'll get support there. I myself feel that if you build your machine from scratch without having your parts lazer cut, then it in itself is some fine engineering well done.
@DadHav First I like to add that this is a Great Video I have a couple questions. I did a little research of my own I noticed that the chart ( AacCBbaACcbB) and their colors that represented each letter, question 1 did each color represent one of the three phase and question two is each face in your set up connected to a different phase like in the Delta connection or does each face starts in and with the same phase?
@elson You're pretty close. A's are one phase, B's another and C's the third phase. Capital letters are wound clockwise and small letters counter clockwise. The numbers 1-12 represent each of the 12 legs of the stator. In the video I have the phases terminated in Delta which means the end of one phase is connected to the beginning of the next. I actually use Wye / Star more often which means the ends of each tie together. Do a search for powercroco winding calculator.
JOHN, I AM ONE ONE OF THE 65 YEAR OLD KIDS THAT STILL WANTS TO KNOW WHAT I WANT TO DO WHEN I GROW UP. THIS PLANE HAS ONE OF MY HAND WOUND OUT RUNNERS IN A HOME MADE FOAMY. I THINK YOYR WORK IS AWESOME. B ENTOAD
I figured as much Ben. I noticed your age on your profile. I'm glad you're having fun with the hobby. I've enjoyed it for 55 years now and still fly a few R/C planes that I built 40 years ago. Maybe I'll make a video of them this season.
I rewind my own motors using burned out cans , but yoursis great.Here is one i wound and put it in a toy boat from good will I used a CASTLE CREATIONS ICE DATALOGGING ESC that I made a water jacket for the motor and esc In this video it ran 100yds in 2.8 sec at 171 amps at 45,000 plus RPMS using a 5000 4s 45 C lipo. WE MUST HAVE TO MUCH TIME ON OUR HANDS. IF I WAS HAVING ANY MORE FUN I WOULD HAVE TO HIRE YOU TO HELP ME. bentoad@cfl.rr.com
Wow, You really know what you're doing. Yes, or maybe you should be working for me. My eyes and reflexes aren't as good as you young guys. He he. I probably shouldn't mention it, in case it doesn't work, but I'm working on a hybrid design that might be very interesting. I'll know the results in a few days.
@FlavoredCoffeeGuy I had to to order more parts from Mouser because, I'm moving away from a three phase oscillator to an all digital method of speed control. If you really win a competition, I hope it's for speed and that the coffee really helped.
Hey Coffee. Some of the better speed controls have some master minds behind them. It would be great fun if you could out do them. My reflexes aren't what they used to be. The fastest plane I fly at this time will do around 130 mph, but that's a nitro engine. I would bet an electric plane could really move over a short flight time. I'd have a crack at a Watt Rocket.
Hi thanks for taking the time to share the knowledage information, how can i got those motors, do you have some of those motors for sale?, i am a mexican hobbyst, living in San Luis Potosí, MX
I am beginner on this, i want to make a quadcopter... thanks and kind regards
Hello my Friend. I don't think you want to make the motors yourself, but any hobby supply or local hobby shop sells the brushless motors, speed controls and batteries that you need for such a project. There are also forums on the Net where people are building these. They make all the correct recommendations there. Search around for a Quadcopter forum.
Hello. At the time I could only have a 10 minute video. That's why I had to switch slides so fast. I have a very similar motor running on a video. Check out Powerful Hand Made Brushless Motor.
@DadHav I did check some other videos. Pretty impressive. Aside from the pride of craftmanship, are your motors much more powerful/cheaper than a store bought item? Just curious.
Good question. When I make a motor it's usually because I want a custom winding or a special physical change to make it more custom to my model. At one time I was using magnets and laminations that wasn't a standard on the market but now I think there is good quality motors available for a good price. I probably still make them precision enough the use closer air gaps an more copper than some though. The time it takes is what makes them expensive.
Whow, You are extremely gifted, very knowledgeable. This takes an indepth understanding of geometry, architecture, physics, maths, electronics, fabricating and so much more.....Well done
See if you can catch it in the video. This motor is an outrunner. You will see the inside stays still while the outside does the turning. This gives an opportunity to get speeds usually only obtainable if you had gear reduction. Th in-runner on the other hand has an armature that rotates on the inside. The smaller diameter makes it more adaptable to high RPM applications.
Hello. Great videos on your channel. I guess the winding would be a matter of preference. I find I can get much more copper on the stator with the multiple strands. For me to get the same circular mills with a single strand it would be so thick I don't think I could wind it.
Sorry we will just have to stay in disagreement on the subject.. It's a proven fact that the larger diameter wire when wound leaves a great deal of empty space compared to filling the area with smaller wires. What would be heavier a jar filled with 10 mm bearings or a jar filled with 5 mm bearings. You could even paint them if you want..
I think people should commit to explaining what their doing on their videos. That would make things much better. The slide show gets the point across even though I had to condense it down to 10 minutes. Hey I love the video of Scruf trying to eat the pine tree.
wow, I wish I could afford a good lathe, I learned how to use them in HS and I fell in love with those things. its amazing what yyou can do with a lathe and a milling machine. nice work man, I really admire all your work!
nice work! but i guess ill buy one from hobbyking cause i think thats gonna be more expensive and it will definately take more time than the shipping from hk...
Well you do know about the two terminals on a standard DC motor. The outrunner motor like on the video is a three phase motor. This is how it can run without having brushes. To run one of these motors you need a three phase speed control which is available at your local hobby supply outlet. All together it's a really huge improvement over the brushed motors for the R/C hobby.
They used to better for sure, but now most manufacturers use the strongest magnets possible and thin lamination stators. I build mostly for fun but It gives me the chance to better match the motor to my needs.
Hi john. Nice work. After seeing your slideshow for maby 10th time, i noticed on one picture that it seems like that you are using a 'metal tool' for cutting the edges of your laminated stators. To my knoledge the stators are laminated for the purpose of beeing non conductive, so to have many isolated layers of great magnetic soft iron. My thought is that you risk making shortcuts between layes, and by that lowering the performance. Just a thought
Kent, You're thoughts are well taken. I shouldn't have used that pic in the set. There is a risk of separating or bending the laminations if aren't really careful. These particular stators have very sharp edges that nick the wire when you wind. Tape could temporarily be put over the edge but that gets to messy to work with. Also these are already shorted together. It was one of the first things I checked when I saw a machine punched impression holding the stack together.
Wish I have at least the knowledge to understand and design a motor.
I have some tools, but no, no lathe. So, a lathe is the instrument for real mechanics. No more looking around for parts, thinking what to use, and where to use this interesting piece you have. With a lathe, priority is on the needs, you design, you make. Homo μηχανικός.
Anybody can do that. It's the easy way out. Just kidding. I have built Scorpion kits and worked with one of their representatives here in the states. They are very good motors. As far as Hobby King: You get what you pay for. I've had some good motors from them though. The price is good. Just read the reviews before buying.
Thanks for visiting.

davidwatts007 7 months ago
@davidwatts007
Almost any DC motor with permanent magnets can be converted. Larger stators are found in some ceiling fans, the flat radiator fan motors, Smart Drive washing machine motors, I use some large size office printer motors. You can find them on E-Bay by typing a search for Printer Mains Motors. I just heard of an excellent choice: A 48 volt hub motor for an electric bicycle makes a good generator that doesn't need to many RPM's

@davidwatts007
There are kits and parts available for making the R/C size motors. An excellent site is Inov8tive Engineering. This is a Scorpion motor site ran by a great person to deal with. If you go on the LRK TorqueMax Group on Yahoo you can find everything you need to know about building a motor as well as links to suppliers.
Hope this helps.

@Bubbelmax
Yes, I enjoy making motors. At one time they where better than most from the store. There is still an advantage
to making them if you have a special need. As an example I have one in a vintage Aquila Grande sail plane. I needed one to be moved back in the fuselage for both balance and fit, so I simply made a magnesium bearing holder / motor mount that put the rotor where I needed it. By the way the plane weighs 4 pounds and climbs out at about 60 degrees.

The machining shown here is truly superlative! Every CNC machinist really needs to learn the old manual techniques shown here first in order to understand proper feed/speed/horsepower calculations, tool path and more. I witnessed more than one young hotshot in engineering school who could not understand why you cannot cut stainless steel at the same speeds speed as aluminum. This author shows how to properly think ahead and plan ahead, before putting tool to metal. GMP followed properly.
sameoldsameold1 8 months ago
@sameoldsameold1
When I started the trade. We had what was called a buzz box. This was a stylus that went on the spindle of the milling machine and was wired to a speaker with a buzzer circuit. We would make a plaster mold of what we wanted to cut and paint it with a carbon base material. You turn the mill into a tracer this way. You can move XYX, touch the model until you buzz while the end mill is cutting in the steel. I know tons of old tricks like this.

Yes, I'm a member there, but don't spend a lot of time there. The small SX-3 milling machine I use is a popular choice on their forum for conversion to CNC. You're right it is a quality forum with talented people. I have a strong background in CNC and was involved with retrofitting some large machines but my love is in the hand machining era. It saddens me to see it slowly becoming a forgotten art.

@DadHav It seems the majority of people on homemodelenginemachinist feel that cnc is cheating, so you'll get support there. I myself feel that if you build your machine from scratch without having your parts lazer cut, then it in itself is some fine engineering well done.

@DadHav First I like to add that this is a Great Video I have a couple questions. I did a little research of my own I noticed that the chart ( AacCBbaACcbB) and their colors that represented each letter, question 1 did each color represent one of the three phase and question two is each face in your set up connected to a different phase like in the Delta connection or does each face starts in and with the same phase?
elsonergeorgia 9 months ago
@elson You're pretty close. A's are one phase, B's another and C's the third phase. Capital letters are wound clockwise and small letters counter clockwise. The numbers 1-12 represent each of the 12 legs of the stator. In the video I have the phases terminated in Delta which means the end of one phase is connected to the beginning of the next. I actually use Wye / Star more often which means the ends of each tie together. Do a search for powercroco winding calculator.

Hey Coffee. Some of the better speed controls have some master minds behind them. It would be great fun if you could out do them. My reflexes aren't what they used to be. The fastest plane I fly at this time will do around 130 mph, but that's a nitro engine. I would bet an electric plane could really move over a short flight time. I'd have a crack at a Watt Rocket.

Hello my Friend. I don't think you want to make the motors yourself, but any hobby supply or local hobby shop sells the brushless motors, speed controls and batteries that you need for such a project. There are also forums on the Net where people are building these. They make all the correct recommendations there. Search around for a Quadcopter forum.

@DadHav I did check some other videos. Pretty impressive. Aside from the pride of craftmanship, are your motors much more powerful/cheaper than a store bought item? Just curious.
skaaltel 10 months ago
@skaaltel
Good question. When I make a motor it's usually because I want a custom winding or a special physical change to make it more custom to my model. At one time I was using magnets and laminations that wasn't a standard on the market but now I think there is good quality motors available for a good price. I probably still make them precision enough the use closer air gaps an more copper than some though. The time it takes is what makes them expensive.

I am trying to notice the difference between outrunner and inrunner motors. Is the one you built on the vid an outrunner?
tahoeskiier 11 months ago
@tahoeskiier
See if you can catch it in the video. This motor is an outrunner. You will see the inside stays still while the outside does the turning. This gives an opportunity to get speeds usually only obtainable if you had gear reduction. Th in-runner on the other hand has an armature that rotates on the inside. The smaller diameter makes it more adaptable to high RPM applications.

@michi386
Hello. Great videos on your channel. I guess the winding would be a matter of preference. I find I can get much more copper on the stator with the multiple strands. For me to get the same circular mills with a single strand it would be so thick I don't think I could wind it.
Thanks for watching.

hi
thx :)
a thicker wire is better than multiple thine ones :)
i didnt believe it too...., but there is a lot of paint on the wires!!
its a lot of work for sure....but we made some motors with very thick wire, and they perform just awesome :)
(but as is said, a looot of work :D )
cheers
michi386 11 months ago
@michi386
Sorry we will just have to stay in disagreement on the subject.. It's a proven fact that the larger diameter wire when wound leaves a great deal of empty space compared to filling the area with smaller wires. What would be heavier a jar filled with 10 mm bearings or a jar filled with 5 mm bearings. You could even paint them if you want..
Glad it worked for you, but it's not for me.

@tailsmilesprower24
Well you do know about the two terminals on a standard DC motor. The outrunner motor like on the video is a three phase motor. This is how it can run without having brushes. To run one of these motors you need a three phase speed control which is available at your local hobby supply outlet. All together it's a really huge improvement over the brushed motors for the R/C hobby.

DadHav 1 year ago
Hi john. Nice work. After seeing your slideshow for maby 10th time, i noticed on one picture that it seems like that you are using a 'metal tool' for cutting the edges of your laminated stators. To my knoledge the stators are laminated for the purpose of beeing non conductive, so to have many isolated layers of great magnetic soft iron. My thought is that you risk making shortcuts between layes, and by that lowering the performance. Just a thought
kentbure 1 year ago
@kentbure
Kent, You're thoughts are well taken. I shouldn't have used that pic in the set. There is a risk of separating or bending the laminations if aren't really careful. These particular stators have very sharp edges that nick the wire when you wind. Tape could temporarily be put over the edge but that gets to messy to work with. Also these are already shorted together. It was one of the first things I checked when I saw a machine punched impression holding the stack together.
Thanks
