Treadmill Motor

I have an old treadmill that the circuit board went on. The main belt is driven by a 120 volt DC motor as shown in the attached picture.
Can i purchase and install a 120 vac to 120 vdc converter, and then hook in a light switch dimmer/rheostat to control the speed of the motor ?
If so, any recommendations / advice would be great.Name:  20131230_073618.jpg

You will quickly burn out most commonly available light dimmers. Unlike a incandescent bulb, the motor presents a very low resistance load at startup.

I'd imagine for the price of what you would need to jury rig it, you could get a new board if the treadmill is in good shape otherwise. I have a reference somewhere when I was fixing a few at the gym. The guy really knows his stuff and has upgraded boards that fix the factory issues. Most of these things are made by one company and use the same parts.
