I was thinking, if I have a somewhat high (50-60 volts) voltage DC (or maybe even an AC motor) motor, would it be possible to use an audio amp to drive it (put it through a bridge rectifier and filter cap of course)
Then I would be able to use a 12V car battery and also be able to vary the power going to the motor by controlling the input to the amp.
I cant think of anything wrong with doing this, but maybe Im missing something. If this does seem like it would work, which class of amps would be better to use?
I probably wont do something like this, but Im just kinda curious as to if it would work or not
