home made wind turbine/generator/motor

[Carlos007007ful]

Hello friend, 75 rpm, 12 volts?

 could charge a battery?

[coyleo1111]

went to yr site no fone number to ring yous i will buy asap plz get back to me

[KireinaHana]

Rpm per volt is not a linear equation. Every percent rpm lost actually equals a greater and greater percent loss in power.

[Kevakazii]

hi all i need someones help, i understand how to build the turbine and what motor to select but im confused as to what i need to buy in order to get the power from it. What cables do i connect to the motor and how do i connect them to batteries as to charge them, feel free to inbox me if u have a clue.

[writerNB]

@Kevakazii - I've only worked on low voltage devices professionally while high voltage TVs remain a (lethal) hobby. Haven't built a wind turbine (yet) so these are educated guesses. DC Motor will produce a max amp output (max load). Correct cables support that maximum load (current). Eg: 4mm cable can carry a max 25amp load. Safe designs include a "dump load", DC isolator, blocking diode and charge controller. All electronics start with safety guides - even small amperages can stop our hearts.

If you could get The New and Improved Generator to work than that would be that best generator.

[beamerboy325e]

Hi, nice video! can I use a 3 phase motor from a home air condition unit?

[windturbinesinc]

We always consume electrical energy in our households. Businesses consume more than regular usage. Since the use of power supply is constant and the growth of power usage is too fast. It can result to a power outage and just being resolved by simply using generators but generators are expensive. Then there's wind power, the cheapest way to replace generators since wind is just free. 

[dapieman123]

can you sell me one.  I am doing a science project and I am making my own wind turbine. I'll pay up to 20 american dollars. You could send my the motor and I'll send you the money.

[pyroman675]

what are you charging?

[wilbeckj]

Nice wind generator, but if I understand right, you can just simply hook up an electric battery to a windmill, that produces electricity? thanks.

[SuperGreenfreedom]

Amazing video!

Thanks!

I am looking to build my own wind turbine already crafted some PVC blades and a tower to put the generator on.

So yes the main part is missing, i am trying to find some sort of DC motor here in europe that has the specs of your motor, no luck yet :(

Also I am trying to convert a ceiling fan to a generator (muddymudman's tutorial)

only problem so far are finding the materials here in europe.

Many greetings and love to see more of your video's!

[iownudie108]

u cant get it that fast with a simple blade, u need some gears dude!

[SmallWindTurbines]

nice explanation for a science project or tinkering around to charge a battery

[foil666]

Portugal? Well, maybe I'll see you around buddy.

[ocendo1]

I have the same motor,only litle beter-230 V-DC,4800 rounds,2000 W,cant find good charge controler vith dump load.Can you sugest some solution.All of new sold wind turbine are tree faze AC generators.Thanks

[happygameshow]

what happens when it goes faster then 340RPM?

[gophomaxx]

amperes are important, more so than the volts when you are calculating electric power. what is the amps?

[redsam888]

thanks man, gret video!

[lloyd21964]

Cool enough idea, I appreciate the post. As a novice, I am going crazy with trying all the (great) and some, (not so great) ideas. I am still going to keep an open mind about new and alternate ways of keeping our country going, I have a feeling things may get a little crazy. Love and Peace.

Lloyd : )

[vox1philippines]

nice DC motor, maybe  i mizz to hear, how nany ampere has your motor? thankz...

[dogfacecow]

340RPM..! That is fast. I was interested in having a hand at a magnetic turbine, i am still at the very beginning stages, just doing light research on the internet.

Do you really expect to reach 340RPM, and that is just to begin minimum charging.

P.S I tried joining your Forum but it keeps saying I'm answering the what year is it question wrong

[humbertini900]

@dogfacecow

hi buddy the year please put 2009 to join the forum thank you

[willavr]

@dogfacecow 340 rpm is quite slow...

[droppermyth1]

pretty cool motor, can you sale it out to me for 3 USD ?

[humbertini900]

@droppermyth1

3 dollars buddy, you can get it for 1 dollar ,just for you, since i understand from your clever comment that you have the capability to build a complete turbine, i am able to swap it for your computer though, you send your laptop first.

see u at windchasers but then again maybe not you are probably too busy being the town's clown.

[CaseyRedDragon]

remember thats ac

[mccunecp]

cool video I have one of those I have gotten few off free cycle one had that motor and the other had one that didnt have magnets as the stator it had the coil of wire and wire for the rotor, and this is a good motor I'm going to use it for a 24 volt system but use a regulator to keep it at 24 incase it goes above 24 bolts or realy 26 for a good charge. again great video.

[ChrisPCrunchy]

DC Motors have brushes and commutators which make them less efficient more maintenance intensive than brushless perminent magnet alternators. You would be suprised how quickly brushes & commutators wear down when turning 24 / 7 A treadmill isnt rated for continous use like a car alternator is. There are regulators that can allow a battery to charge from any voltage input even AC. modified car alternators are a better solution as alternators are more common and can be easily modified.

[arthus1971]

what about de Current generated? in 12-24-48 volts

[arthus1971]

hi, is the formula correct for to know how many volts you need? how you get it? thanks good video and info, please answer, bye

[jakehealthx]

you have a sexy accent

[HomeWindTurbines7]

Hello, I like the clip that you posted here. Recently I posted a video of my home wind/solar, go have a look if you are interested in home wind energy. Posted video of my install of rooftop wind turbines and solar panels at my house. If you Favorite my videos or Subscribe that would be great. Thanks

[mocca61]

you could make some gears to ajust the rpm !!

[jarekdadej]

The motor you are using has a hing nominal RPM witch is not the best. I am working with fitness equipment and i see those high RPM motors sometimes in a cheap treadmills. The more expensive treadmills like Precor use low rpm motors(2600 3200RPM) witch makes much better use for wind generators. I have about 10 of those low RPM motors laying around and i have to put them to use, maybe sell few on ebay....

[pusswhakker]

You do your calculation for a 200 volt motor, but you said it is a 300 volt motor. All your calculations are off by 33%

[natedogg1026]

Thank you. Informative.

[danthemanzizzle]

how do you charge a battery without the battery powering the dc motor

[pauluminous]

put a diode in between which restricts the power flow one way only.

[MandLVideo]

I live in a heavy wind area, these motors just need to many RPM to make them worth while. Fast blades or not, but fun to play with though. I have built about 5 of the turbines you are showing. If you could find about 1000 RPM motor that may work. The best turbine I have found is the axle flux this is a serious turbine.

[glenisah]

Thank you for explaining it so thoroughly

Keep in mind that a fully charged 12 Volt lead/acid battery's voltage is around 14.2 V-14.3 , below that is not recommended.

We learn By sharing information and I thank you for sharing yours

[565Customz]

no its not its 12.6 14.2 is the voltage made by a car alternator..

[humbertini900]

Lets just say in practise that we need at least 13v from the motor to start charging the battery there is alot of play with batteries, i.e condition, temparature, voltage etc.., this is just a quick video to give beginners an insight into wind turbine motors.

cheers for the comments guys.

windchaser

[565Customz]

yes you do need 13 volts. the reason is that you need to exceed the voltage in the battery to force juice into it (voltage is push) so if a properly charged cell is 2.1v..times that by  6 you have 12.6v...so technically...if you have 12.7, or ever 12.61 you can charge the battery, just would take to long lol

[Avman3369]

2.5v per cell by 6 = 14.8 v in a fully charged 12v battery so you need over 14.8v and good current to charge the battery fully

[anewlow23]

@humbertini900 How many amps do you draw normally from this motor at thirteen volts?

[greatwhitenorth112]

@565Customz ive only seen 13.8

[565Customz]

@greatwhitenorth112 its variable.

[Hasus1n]

can i use a motor from a home ventilator for a first time wind turbine??

[nathan82206]

so if you spun it at 1150 rpms is would abruptly make 200 volts? and do you think a motor in a sweeper would be good enough for a first time wind generator??

[Jackson41031]

Nathan82206, has a good question. Does anyone have information, on where one could find

practical DC motors? What are some of the appliances, that use them (e.a. treadmills) Love your video. Keep up the good work!

[ripadisc]

i also have the same type motor and have the blades made but am worried about a breaking system

[windman1000]

This Is A Good Video And I Dont Want This To Sound Negative But After You Calcilate Your Calcilation Like You Did Then You Need To Spilt Your Voltage Aprox 50% For Load, Example

If you Had 26 Open Volts At 660 RPMs And Say 18 Shorted Amps It Is Really Aprox 13 Volts And 9 Amps Charging At 660 RPMs

So When Calcilating You Basically Need To Double Your Rpms At 13 Volts.

I Have Found This True On Every DC Brush Motor I Have Tested Even The Same Motor You Have Here.

[billykash]

I'm just learning. If its hooked up to a 12v battery is that considered a load?

thanks

[whitetail54]

great video,thanks for posting

[TheWindMillMan]

boo

[michael970]

hello have you tried to run two motors in series neg to positive it seems to make twice the volts I have done it but dont know if it does any good or not let me know what you think about it thanks

[humbertini900]

why don't u join my forum and soon I will put up how to make the blades, cheerio

[droppermyth1]

@humbertini900

you are trying to overcharge me for this motor, my COMPAQ notebook had cost me 1200 USD. & I dont think your motor will cost the same!

-------------

Well this is a final deal b/w you & me, I am glady paying you 4 USD. (Thats final)! Since this motor is not a brand new one.

I've made myself a hand-gear generator, with a small hand rotations e.g. 3 RPS (Rotations Per Second), it produces 6-8 Volts out with 2 Ampere!

-------------

Gear box converts 3 RPS x 5=15 Rotations/Sec

[kryptiea]

Very good vid. Im working on almost the same motor right now, Show us how you make fast blades

[dmacosta1]

Thank you

[ricardoscarpentry]

WELL DONNE
