In the electric motor, the stator includes a first winding,
energizing the first winding with periodic pulsed power in which the ratio of the energized time to the non-energized time is varied based on the size of the load driven by the motor;
The rotor includes a second winding provided at a position where alternating current power is induced by energization of the first winding, and this second winding.
A rectifying element that rectifies alternating current power induced in the winding, and a rotor winding wound so as to generate a magnetic field of the same polarity as the permanent magnet when the output power from the rectifying element is energized. An electric motor featuring: (2) The electric motor according to claim 1 of the utility model registration, characterized in that the electric motor is equipped with a control section that cuts off the power supply to the first winding when the load on the electric motor is light.
