what kind of motor is it? ac induction motor? or are you rectifying the mains for a dc motor? if its an induction motor you can get a vfd and feed it a different frequency for your desired speed. If its brushed dc you should be able to adjust the voltage for the desired speed.Greetings. First time post from a complete newbie. DIY enthusiast ... would like to buy a mini-lathe for some hobby projects BUT the motor generates 4000 - 7000 rpm. For working wood this is great but I also need it to drop down as low as 250 rpm. I was thinking I'd need to put a potentiometer in the circuit to give me a true variable speed of 0 - 7000 rpm.
The motor runs on mains electricity, and is rated at 96W and 12-24V.
Two questions ...
1. Can it be done?
2. If yes, what are the potentiometer specs I'll need to make it so?
All help very much appreciated.
Cheers.
