I seem to recall that the power supplies were commonly used to power LED lighting. Here is a photo of the Motor that I used, the box that I put the controls in and a crude wiring schematic. I added

I've had a look around on Ebay, specifically for units that will be simple to use, and, ideally, stocked in the USA. For a power supply, these four listings are for exactly the same thing, from USA

Keith, I bought two of the 150W 24volt dc brushed motors. The price was right. I will look around on EBay for a 24 volt power supply and a speed control. I am going to search back in your posts for

If you use 150w motor, a 200w power supply is more then enough. You will find that the power supplies under rated and are designed to take a brief overload without blowing.?Jeff

The type of motor, and the type of DC drive must match up, maybe not exactly match in all ratings but they should be close.? A motor with brushes requires "brushed" DC drive, and a brushless motor

The two wire 24 V DC motors are brushed - the muttering about brushless motors has been a red herring? - the KB controller would not run any of them. Brushless motors need their own specialised

Keith, I contacted KB Electronics by phone today and was advised directly by a customer service manager that I cannot run a 24 volt dc motor with the KBMD motor control I have. There is no way to get

Hello Dick: U90 motors have some demand, you might recoup your costs by selling them. Personally I would keep them as spares. I'm still using my U90, but bought a replacement DC motor ( 30 years ago,

Jeff, Thanks much for your answer! I think I am going to pull the trigger and buy two of those motors tomorrow. I am going to replace the two U90 motors I have now. The U90 motors are old but have

Yes and yes. It is quieter then the stock Unimat motor by far. I just went down stairs and ran both. Just using these 66 years old ears, it seems to make less then 1/2 the noise the stock motor does.

Jeff, This scooter listed on EBay motor you recommend ( ZY6812 24vdc 150w? motor) is listed as a brush motor. Does it run smoothly and quiet? Thanks, Dick http://www.homemadetools.net/

I see this motor is still on EBay but it is a brush type motor and not a permanent magnet dc motor. My experience with a brush motor has been too much noise. -- http://www.homemadetools.net/ forum/

The KB controls use the 50/60Hz wave as their chop frequency. You'll be driving the motor with very short pulses at 120 Hz and they'll be like spikes. The 24 V power supply is steady DC and the

Provided you are reasonably sure the 24 V motor can withstand pulses of 90 V, I would give it a try. However, if it can't, you could land up with a damaged motor quite quickly. Alternatively, if, by

Keith, KB states my unit is designed for permanent magnet and shunt wound motors DC motors. This control can use 120 volt AC input and is designed for 90 volt SCR rated motors. I want to use a 24 volt

I think the KB controller could well be OK with a 24 V motor, but the motor will be subject to 90 V spikes, and the general insulation might not be able to handle it. They may have used higher grade

Hello, Just for the sake of adding some more multimedia information, to the already very useful and interesting discussion over the last days. Here some YouTube links, that show a scooter?s DC Motor

The resistor is spliced into the wire coming out of the high leg of the speed knob before it plugs into the controller board. iirc the speed knob is 5k, so, I think, to find R1 from

Clark, What resistor would I need to use in my 90 volt KB motor control to get the voltage down to 24 volts and where would I plug it in? Or should I contact KB support for this? Dick --

Keith, I looked for a 90 volt motor that will work with the KB controller I have but they are all higher horse power and too large for the Unimat. So I might end up doing as you first suggested and
