What happens if the starting winding is not disconnected after the motor reaches the rated rpm?

If the starting winding of a motor is not disconnected after reaching the rated RPM, it can lead to overheating and potential damage to the motor. The starting winding is designed for brief use to help the motor start, and prolonged operation can cause excessive current draw, resulting in insulation breakdown and failure. This can ultimately reduce the motor's lifespan and efficiency, and in some cases, may lead to motor burnout.
