I have a 230v dc motor from a clarke mini lathe. I assume I can run it from the mains with a diode or rectifier in place (please correct me if I am wrong).
Again assuming I can, is there a formula for working out what kind of speed I can expect. The motor is supposed to be capable of 4000rpm which I guess would be a constant smooth supply so a full rectifier will? give me about this maybe more as the voltage will be 240 but a diode would give me 50 hertz at 240 volts and this is the speed I would like to know.
I appreciate any input.
