ohh, that electro engine sounds like the Alstom Metropolis subway Linea D (D-Line) trains that passes near my apartment, search for alstom linea D and listen, its sound very similar!
I have noticed something, while reading your post, didn't you know or you did?
That cooling this motor with fan would be better to pull the Air out of the motor rather than trying to cool it from the front. A reverse winged fan required for this situation.
The motor doesn't have any cooling ribs or discs. So the air pulling solving aerodynamics problem.
@oleglyan hey thanks, no I did not put any fan on the motor yet. Pulling air out of the motor makes a lot of sense. I could try to design a propeller in Solidworks and get it printed in 3D. In the beginning, I wanted to force air IN the motor. Because it is easy for me to get a normal propeller from RC ducted fan and make it fit on the end of the motor. I have one at home ready to me modify. I will blog about it when I get there. Thanks for your idea!
@bitsurfer0101 It is from a "toy r us" electric scooter. The original scooter is 150W DC motor. I took the pulley and belt from that old scooter. I recommend you take a #25 chain! I spend to many cash on buying belts! I broke at least 4 of them. Check my blog for detail pictures and how I made it.
@oleglyan LOL! I also had some ideas to make a asian style 3kg sumo with magnet with brushless motors. It spins to fast. You need at least a ratio of 4:1. I have to many ideas, one project at the time :) Good luck!
i do not think i would want to ride that thing too far seems unconfortable and dangerous considering the power it has and i sure would not want somebody else controlling it while i rode it
@bernard240vdc I can tell you it has change considerably since that video! Really nice to ride and I have control over with a throttle! It is fast. I do have video and I will be posting them. Thanks!
@RoboTekno I use a speed controller from Hobbyking website. A 100A version. I have my own arduino on it to controller the throttle. You should build one, it is really fun and you learn a lot of stuff! Have fun!
@JeromeDemers Awesome, I've always been curious about arduinos and DAQ boards, etc. What are some good ones to start out with and what kinds of things can you do with them?
As for the scooter, I thought of modifying a servo tester and just hooking that to the speed controller.Also, how many amps are you pulling on your setup and did you use the scooter's stock drive train?
@RoboTekno visit my website for many many more detail and pictures jerome demers dot com. Also that is stock gear train. The setup consume around 20A to 80A I have peak over 100A. Genereally it is 60A peak. There is many factor in consideration of current.
@McBlaise There is Charles from MIT that already did that here is the link
etotheipiplusone [DOT] net/?cat=63 You can also search for "equals zero" on Google and the first link is the one. You will have to look on the left hand side menu for "RazErBlades"
1480W *continuous* with such a tiny motor?? I'm having a very hard time believing that! I'm not saying it's not true, it's just really, really amazing. Any scooter, electric bike, hell even my 750W skateboard achieves far less power with a much larger motor, and often at temperatures high enough to cause pain or injury if touched. Clearly the through-air cooling has to be part of the difference, but I'm still amazed.
@trippedbreaker Yes it is true, first there is a legal limit on commercial ebike and scooter. It depends of country and state but it is under 1 HP or certain amount of watt and/or speed. Electric bike a "lock" to a specific speed. same for segway. You have to remember the cost factor. That motor cost WAY more then DC motor. It needs a very complex controller, special batteries, that ends up been for exemple a 2500$ scooter. You pay 500$ for you scooter. It's not gonna sell.
@spidersinspace I 100% agree with you on the wheelie bar!!! Oh boy it's dangerous. Yesterday I hit 32Mph with the scooter and a new motor and new batteries!!!!!!!!!!!!!!! Video will come :)
@agent700able Start by having fun with your scooter. When you want to go faster, the most easy way is to change the controller and go up to 36V. You will need a other 12V battery to go from 24+12=36V Start with that. Maybe you controller can handle 36V, just google around.
Awesome! Awesome! Awesome! I have your site bookmarked. lol! So I'll be monitoring the progress. I actually went ahead and made mounts for the 3rd bearing and even a 4th bearing--bearings on both ends. Also, I know on your site you have some fan mounted on the end, spun by the motor. Are you running that fan? I know the endbell on the Turnigy is kinda designed to create a little bit of airflow.
Hey! I have a similar motor, but 270kv Turnigy. I have a somewhat small scooter that I'm building . I've been to your site and have followed some of the progress. I am curious, how has this motor been doing as far as heat? What about the need for a 3rd bearing at the end of the shaft? You don't seem to be using one. No probs huh? And lastly, you say in the video you're running it on 14.8V(16V loaded). Is that throughout the whole video or just the bench test? Thanks.
@dzaster96799 Hey, I have been riding version 2 of this scooter like hell! More then 15 kilometer.All my friend have been on it, from 90lbs people to 215lbs people! At 16V, the motor does not heat up more then 60Celcius. In the video I am only at 14,8V.No need of third ebaring on the end of the shaft, could be smart thing. I have a ton of videos to upload and got many things for the website. I just finish my finals, so I will be updating things. I am working a on a belts tensionner.
I'm thinking of doing something similar, probably with a small child's bike. How feasible do you think it is to make the can of the outrunner contact the rear bike tire to make a sort of friction drive? Kind of like gears without the teeth, I guess... Also, what is the current (A) rating of the speed control you used? I hope to source all my components from an RC plane/boat online store...
@JeromeDemers Cool, thanks! I'm thinking of using parts from HobbyPartz (a US supplier of HobbyKing-type stuff) including a "Monster Power 245Kv outrunner motor." It runs off 10S LiPo (although I'll be using 3 lead-acid packs for cost reasons) and has a max. output of about 2500W! I will also need a high-voltage ESC for that (I think a 70A or 80A). This will be going on a larger scooter - the type that has little tires like from a child's bicycle - so I think the extra power will be welcome!
@noyz2k The ratio is the number of turn for the motor do to so the back wheel spin 1 complet turn. In my case the motor has to motor has to spin 5 times to make the back wheel spin 1 complet turn. So the 188:16 like you say is not a ratio! You have to divide those numbers. thanks
@JeromeDemers I actually meant to make my first post a suggestion, rather than a command :P sorry. "You could use hall sensors..." Anyway, people have mounted them on the outside with good results. Check Endless-Sphere forums for details. I'll pm you the link.
@berliner51delux I did not tested that, I would say under 10 minutes with the battery I have right now. I can add more and get better range. I only have 5A. I am making version 2 an will be testing the range this summer.
@heberorozco No I will not burn my ESC. I have a 100A ESC and the motor takes around 40A and up. I got oncea peak of 143A and did not burn anything. With pinions that is too mechanicallly complex, have to align everything. I will use a chain in my version 3 of the scooter.
Heh, this is pretty cool. I'm planning on making something like this with my combat robot parts, except I'm gonna make the scooter about 6 feet long and use a 6,000W brushless motor at 44.4v (12 cell LiPo). It should be interesting. This video gave me some good insight as to how I should make it.
@Airazz I have no clue for the moment. I did not test that. The battery are 5000mAh.I guest I could roll for less then 8 minutes. I am waiting for news motors and will test it.
I'm looking into a similar project, and I'm thinking about using some rubber rollerski wheels for added traction since those hard plastic wheels are dangerous at such high speeds.
how did you run that motor without the hall effect sensors?can you show me a video? i would appreciate it much cause i have a brushless motor that uses hall effect sensors but i want to run it wihtou the sensors,.thnx!!
It is a sensor less Remote Control (RC) controller. All RC controller are sensorless. You don't have hall sensor to tell the controller when to active a certain phase. Those RC controller use current feedback to determine when to trigger the next signal. It is more simple to control a brushless motor with hall sensor then without them. I am talking about coding and building your own controller.I am working on that. Search your motor on google andcheck how other people have made them.
thnx!!..hope youcan make a video running a motor with hall sesors,.this one im trying to work on is that the original electronic circuit doesnt work.well,hope to see more of your videos how these things work...
@JeromeDemers: That sounds like a Castle Creations controller! Have a look at my brushless motor videos - I'm building a 72kW controller that is currently powering a 7.5kW Turnigy motor. It works sensored and sensorless.
@KippTheKidd Thanks for the link, I checked all 3 videos, pretty nice! I still don't see any electric bike with that controller! :P That is a not a castle creation, it is a hobbyking 100Amp 100$ controller. I am also planning on building my own controller. Nice work btw!
HAHA! I have been thinking about that since day one! I do have some roller blade wheel and stilll thinking about it. It will be a lot of work and might try something. Thanks!
Cool. I also upgraded a scooter with an outrunner motor and used an ESC. I chose a more robust, but still lightweight platform, to base it off of and it regularly sees 31 mph with 33 volts (a123 batteries). To increase the speed, I would need to increase the voltage and my simulator predicts about 42 mph at 50 volts (The max voltage of the ESC). But, you know, 42 mph on a small scooter is nuts.
I now go up to 25mph, (40.3km/h) and that is very very fast and a little bit to dangerous. I have 33V of lithium battery. The prediction with the simulator where 43km/h at 36V. If you go 42mph, that is more then crazy. The problem I have his popping a wheelie at 20mph, not good! I end up crashing in the middle of the street at around 21mph :) I am working on software algorythm to smooth out the acceleration and remove unwanted spike. I will posting new video of the top speed!
I'll admit, I implemented current limiting with my small scooter which helps with the wheelies. As a result, it also accelerates less quickly, but that's ok if it means no wheelie danger. :)
It also has a throttle ramp where it "slowly" increases the throttle from zero - this is designed to help with the wheelies and I found it's pretty essential for current limiting.
If you want to see the details of my build, you can search for "My Outrunner Upgraded Small Light Viza Volt Scooter" (include the quotes) on the endless-sphere forums and you should see a thread by swbluto.
Hey Julian! I remember seen your video, really neat, you need a video of it in action! You also need a chain tensioner to prevent the random mouvement in it. As I write this comment, I am finishing up my scooter with 2 x 14.8V battery for a total of 33.5V fully charged battery 5A each. I am going to test it tonight! Thanks
hey thanks, I did test with dewalt 36V battery. The battery has a smart electronic circuit inside that won't let you drain a lot of power. The battery will shut down ( protect it self ) I was once able to record a peak of 65A. Normally it goes from 25A to 40A, the Dewalt battery does not like that. I am working on something. Using a coil.
Attend de voir la version 39V! Je vien d'aller faire un video, c'est mongole comment je me déplace dans le video. Travail sur ton char toi! Contact moi si ta des questions.

I am talking about coding and building your own controller.I am working on that. Search your motor on google andcheck how other people have made them.

thnx!!..hope youcan make a video running a motor with hall sesors,.this one im trying to work on is that the original electronic circuit doesnt work.well,hope to see more of your videos how these things work...

@JeromeDemers: That sounds like a Castle Creations controller! Have a look at my brushless motor videos - I'm building a 72kW controller that is currently powering a 7.5kW Turnigy motor. It works sensored and sensorless.

@KippTheKidd Thanks for the link, I checked all 3 videos, pretty nice! I still don't see any electric bike with that controller! :P That is a not a castle creation, it is a hobbyking 100Amp 100$ controller. I am also planning on building my own controller. Nice work btw!

I have a question....
Was this whole video only 14.8 Volt battery? and was that with it reduced 5: 1?
jpc1105 2 years ago
Yes the entire video is on 14,8V. with a ratio of 5:1.
I will be filming a other video at 33V.

HAHA! I have been thinking about that since day one! I do have some roller blade wheel and stilll thinking about it. It will be a lot of work and might try something. Thanks!

By the ways, is that a school? What country is the school located? It kind of looks like a basement.

LOLL, these are the underground tunnel to go from one faculty to a other one :P It is the University of Shebrooke, in Québec, Canada.

Cool. I also upgraded a scooter with an outrunner motor and used an ESC. I chose a more robust, but still lightweight platform, to base it off of and it regularly sees 31 mph with 33 volts (a123 batteries). To increase the speed, I would need to increase the voltage and my simulator predicts about 42 mph at 50 volts (The max voltage of the ESC). But, you know, 42 mph on a small scooter is nuts.
swbluto 2 years ago
Also, at 31 mph, the motor only sees 130 degrees Fahrenheit. It could easily handle higher power levels.

I now go up to 25mph, (40.3km/h) and that is very very fast and a little bit to dangerous. I have 33V of lithium battery. The prediction with the simulator where 43km/h at 36V. If you go 42mph, that is more then crazy. The problem I have his popping a wheelie at 20mph, not good! I end up crashing in the middle of the street at around 21mph :) I am working on software algorythm to smooth out the acceleration and remove unwanted spike. I will posting new video of the top speed!
JeromeDemers 2 years ago
I'll admit, I implemented current limiting with my small scooter which helps with the wheelies. As a result, it also accelerates less quickly, but that's ok if it means no wheelie danger. :)
It also has a throttle ramp where it "slowly" increases the throttle from zero - this is designed to help with the wheelies and I found it's pretty essential for current limiting.

If you want to see the details of my build, you can search for "My Outrunner Upgraded Small Light Viza Volt Scooter" (include the quotes) on the endless-sphere forums and you should see a thread by swbluto.

@JeromeDemers Ouais vivement de nouvelles vidéos car celle-là est nullissime et ne met pas en valeur ton projet de trottinette brushless.

Hey Julian! I remember seen your video, really neat, you need a video of it in action! You also need a chain tensioner to prevent the random mouvement in it. As I write this comment, I am finishing up my scooter with 2 x 14.8V battery for a total of 33.5V fully charged battery 5A each. I am going to test it tonight! Thanks

Try with dewat batteries(cheaper), it works in diy segways.
The transmition is crutial, some ideas

hey thanks, I did test with dewalt 36V battery. The battery has a smart electronic circuit inside that won't let you drain a lot of power. The battery will shut down ( protect it self ) I was once able to record a peak of 65A. Normally it goes from 25A to 40A, the Dewalt battery does not like that. I am working on something. Using a coil.

good data! maybe you can say me if the lindemann system can improbe motorized machines like yours.

@JeromeDemers Je suis d'accord avec pauliquid ça n'avance vraiment pas vite pour un moteur de 1450W.
Refais-nous vite une vidéo car celle-là est décevante
