Reversing the polarity of the start winding in relationship to the run winding reverses the direction of rotation of all single-phase and three+phase ac
motors. There are only two types: induction and asyncronous. The difference is that induction motors run a bit slower than the frequency they are fed. A asyncronous will run at the same speed as the frequency. U do know what that means right?. Induction, asyncronous, dc
doesn't matter they all use magnets to create force moving a shaft or what ever else u put in there. Unless that coil inside the motor where to magically re wire itself of the poles connected to the 1 and 2 stamped in the connection point. It isn't changing. I read online that there are pieces between the shaft and motor. I couldn't find a technical drawing showing the design though. To be honest I dont care. It's just when I see a statement such as ac
motors run backwards accidently sometimes I can't help but argue.
