My question concerns inductive motors with a start and a run winding. I understand that the start winding has more resistance and therefore more magnetism during startup of the motor. The start winding is offset slightly from the run winding. The induced magnetic pole in the rotor is attracted to its opposite pole in the stator and rotation begins in that direction. What happens if when the motor is at rest it is in a position where the initial attraction is in the wrong direction of desired motor rotation?
I am a machinery technician (not an electrician) and am tasked with teaching other machinery technicians about electrical theory, potential, current and PTC relays, switches, breakers, run and start caps, inductive motors as they relate to air conditioning and refrigeration, and testing and troubleshooting these components as well. Every now and then I still have questions like this and I am hoping to use this forum as a tool to learn more and resolve questions from my students that I cannot answer.
I would appreciate any help available from this resource.
Thanks!
