YaeTek24V DC 350W Permanent Magnet Electric Motor Generator DIY for Wind Turbine PMA

I am using this motor, along with a Drok 115VAC to 24V 20A variable power supply, to drive my Taig Micro II lathe. Considering this whole variable DC drive kit cost about $80 I'm very happy with the result. While not perfect, the value is so high I have to give it 5 stars.If you've been thinking about one of these motors for your micro lathe I say, go ahead! If you are running the 115VAC Marathon motor that Taig sells, then you know about that motor. It's OK, but the speed range with the 4 step pullies is 430 RPM to 1725 RPM, pretty high for larger parts. And it's big, heavy, and kind of brutish - there is no way you need that much power, nor can it even be transmitted with the stock belt.This DC motor setup runs well down to about 5 volts/570 RPM, which is a lathe speed of 140 RPM. It will go a lot slower, but it sounds a bit notchy. It's happier above 5 volts, and I usually have it set about 16 Volts, which makes a lathe speed of 450 RPM to 1800 RPM. The power supply goes to 28 volts and the motor is spinning at 3400 RPM.The motor has plenty of torque for this application. At 7V I have no trouble machining 2" diameter aluminum at a no drama SFM. Once again, the belt is the limitation.The only negative for me is the motor is kind of loud. It makes an ever rising pitch and volume whine as RPM increases. I only use this lathe for occasional small parts, so the noise doesn't matter. If you are doing production, it might get tiresome.Who knows how long it will last. Considering it's intended use as a scooter motor I'm hoping with this very light lathe duty it will last forever.

I purchased this motor to replace a 250w motor on a Razor MX350 dirt bike. This motor fit the mounts and lined up with the chain just as the original. It sounds a bit different but appears to function the same. I did not replace the controller or batteries. I will confirm if there is a higher speed or power with the upgraded motor.

works good

Tested as generator, need high toque, with a small drive motor I obtain 14VDC and around 3 Amps , good for play and tests.

This motor exceeds my expectations. I found a 24% improvement in power efficiency when operating in the reverse ccw direction, (Black =+). the shaft and mating nut are threaded left for normal cw operation which means that it will loosen and possibly spin off from reverse torque. Balance and vibration is good in both directions.

lo quería usar como generador y alcanza voltaje hasta 3v en la máxima velocidad de viento, como motor las especificaciones son correctas para úsalo en bicicleta pero como generador eólico las especificaciones técnicas no lo son las esperadas y su rodamiento es algo duro para que el viento lo pueda hacer girar facilmente

I bolted this motor onto an old Razor E225 scooter, with two 36v hoverboard batteries and a 36v controller, and it rocks. Gets 16.6 MPH with a medium-sized adult, climbs moderate hills without complaint. So far, it’s handling that load well and not running hot.

351 DC motor works great nice strong motor. I would absolutely recommend this motor for any DIY projects. You may have easy to hook up. Hey Siri use I believe anybody could wire this motor up.
