Induction Motors ARE single phase.   A three phase motor is also of an Induction type or Synchronous type. Looking at Ugly's reference book on page 73 they list the different types. =   Both modern single phase motors and 3 phase motors induce current from the =   field winding into the rotor winding without brushes. As there is no rotating field in a single phase motor, extra (start) windings are needed to get the rotor spinning in the right direction. These are then switched out before the motor gets up to running speed. As Keith's motor has 3 wires coming out of it I would think it was 3 = phase. But I may be wrong here too as one could be a ground wire, but then a = green wire should have been spliced to it. Also a 3 phase motor will draw around =   6-7 amps at 240V. A single phase motor about 13 amps. Eric

I believe that you could end the speculation by calling the guy you bought it from and ask him. Regarding wire and terminations I'll try to take a couple of digital photos tonight an email them to you.   Dave Heimer   >

If what I'm describing aurally approximates your experience, then you have a repulsion-induction motor.   Single phase. No question.   > I believe that you could end the speculation by > calling the guy you bought it from and ask him.   He should be able to tell in a heartbeat by looking at it? You got pictures of the motor?   Faithfully,   G.A.   -- Richard Schneider, PRES/CEO SCHNEIDER PIPE ORGANS, Inc. Pipe Organ Builders 41-43 Johnston St./P.O.
