Abstract:
A self-magnetizing motor incorporates a control circuit that starts the motor, controls a magnetizing unit, and then operates the motor. The control circuit can include relay, such as a bi-directional conductive power semiconductor device, and one or more PTC (Positive Temperature Coefficient) switches. This control circuit eliminates the need for a separate controller and the implementation costs can be reduced.
