modifying a single phase motor to a syncronous type by machining the rotor.
Posted by Rustic1234 on 1/12/2010, 7:02 am
Hi, I've been talking to a colleague who is trying to modify a squirrel cage single phase electric motor to syncronise, at 3000 rpm, with the 50Hz mains frequency of the supply by machining 2 flats on the rotor. I just can't see how this, based on motor theory, would work and even if it did I think the motor power and torque would be seriously compromised to the point that the motor would drive its self but that's about it. Can any one give me some technical details / theory about how the concept works?
Many Thanks, Rustic.
