 I'm with Frank, put on a 6 hp gas motor with a hyd pump, way more realiable, infinite speed control plus you'll have hyd for a chain turner, toe boards, loader arms, log stop, clamp etc.   Steve

Stepper motor controllers can only be used on stepper motors.

One of the reasons I used wheelchair motors is the low amps they draw.
Winch motors are high powered motors that draw high amps.
You best have a real good charging system if your going to use one.
The controller would also be very expensive for high amp motors.
Wheelchair motors are geared to turn a 12" wheel at walking speed.
That works out great for the carriage speed. Used wheelchair motors
are sold cheap on E-bay and if you have a junkyard around most of
them have old electric wheelchairs in them. I see about one a month
come in to our local yard. Another neat thing about the wheelchair
gear box is that they have a quick disconnect leaver. For raising the
carriage a wheelchair motor connected to a worm gear winch works
great.

How do you deal with them being 24 volt and the mill and charging system being only 12?

Forget low volt electric go hydraulic and add a log turner too. Frank C.

I would love too but even using second hand parts a hydraulic system gets expensive quick.

I'm with Joe on that. I will be installing two toe boards that will be powered with 12V winches which I have on hand. That will take a third battery, but I don't get on the road with my mill. ;D

 Repairing burnt out malfunctioning electric components get  expensive  plus wasted time, hydraulics will cost less in the long run.  Steve

How do you deal with them being 24 volt and the mill and charging system being only 12?

For $70.00 you can buy a 24v single wire alternator off E-bay.
If you look real hard you can but 12v wheelchair motors.
Most are 24v for a reason. They work better and wire size can be smaller.
Wheelchairs are made to be used every day and they are very robust.
Do an E-bay search for "Invacare wheelchair Motor 12v" and you will see one.
I have had not problems with my system and I would do it again.
you can run a 24v motor on 12v but you will only get 1/2 power and speed.

Ok once you have a 24 volt system how do you get 12 volt to your starter, ignition system (and in my case,) clutch?  Can you tap into just one battery in a 24 volt system to get 12 volts or do you have two systems, one 24 volt with two batteries and a 24 volt alt and a second 12 volt system with its own battery and alt?

My system is all 24v ... but you can put a camper battery inisolator your system
And tap just one battery for your 12v.

E-bay also sells 24to12v converters.

Joe, granted I'am old and opinionated. With hydraulics you pay once, and once you have power feed and log turner you will be loathed to go back to manual rolling. Look back on this forum several pages and count the problems with electric controls, see if you can find a problem with manual hydraulics. Frank C.

If you can get past the requirement for 24 volt electrics (just ask KB how) your best bet by far is the motor and speed controller out of a handi-cap scooter (not a wheel chair) The speed reduction gear box is built in and the speed controller is usually rated at 70 amps. Wheel chairs use a separate motor and controller for each wheel. Scooters use a single, larger motor driving a reduction gear and differential, much more flexible for a sawmill..I have a lot of experience with both types, rugged dependable units. Only problem I have ever seen with the motors is worn or sticking brushes. The controllers, being electronic, do occasionally get trashed..

Some wheel chairs have better motors than scooters have...
