Power feed- how about this motor and controller?

10amp controller with a 9 amp motor is not going to be enough. That motor will pull 12-20 with a load of cutting through wood. I have a wheelchair motor that pulls 7 amps when lowering my saw head, and over 30 when raising it.

If you run a 24v 9amp motor at 12v you will still run around the same amperage. You're dropping voltage, witch drops speed not torque.

Good info. I haven't bought the controller yet so will look at for a 40 amp or higher.

Now remember you probably wont jump as high as mine pushing forward/reverse(mine doesnt), and you can also adjust the speed/amperage ratio with sprocket size. Sometimes that can save your wallet some on a controller by sacrificing a little speed.

After running mine tonight I am running 12 volts through the cut, and changing the reverse to 24v. Way too much time for me going back and I have a 24v and 12v system.

Fred, another good source is electric wheel chairs. There's 2 motors, one for each side. The motors are 24 volt with a built in worm drive reduction box. Still have plenty of power on 12 volts. I have one hooked up as an autoclutch on my mizer. It lifts the wm motor easily. The speed controller may or may not work on 12 volts.

Unfortunately I had already ordered the motor. I think the wheelchair motors may be the best option.

The motor came in today. It is a 3 phase DC brushless motor. I never knew there was any such thing as a 3 phase DC motor. I may have to put it back on ebay unless I can find a brushless motor controller.

Does anyone know where I can find one? Not having much luck searching the net.
