AC DRIVING MOTOR WITH SELF-EXCITATION CIRCUIT OF ANCHOR WINDING SUPPLY Russian patent published in 2013 - IPC H02P9/02 H02P5/46 H02P1/54 

FIELD: electricity.

SUBSTANCE: in an AC driving motor a self-excitation circuit is connected to a rotor of the second motor, as a result of which an additional torque appears on the common shaft of the drive. The drive comprises a primary driving motor (DM 1) of the driving electric motor (DM 2) with the self-excitation circuit of anchor winding supply; and a load (L), such as a mechanism or a generator. The driving motor with the self-excitation circuit of anchor winding comprises the following elements: an AC motor (1), a transformer (2); stabilitrons (3, 4), serving to stabilise voltage on the primary winding of the transformer, capacitors (5, 6, 7), serving to compensate inductances of the winding of the driving motor DM 2, primary and secondary windings of the transformer.

EFFECT: higher efficiency.
