Hello All,
I am wondering if any one has used a Variac to power a DC motor. My game plan is to place an isolation transformer between the variac and the rectifier(I read some where that is a good Idea). The variac would control the voltage out of the isolation transformer and the rectifier would convert this to DC voltage. I would then use a capcitor to smooth out the dc voltage. This sounds simple enough, but I am not sure this will work. I would appreciate any input from any one who has done this.
Thanks,
Joe
