METHOD FOR REGULATING ROTATION FREQUENCY OF ASYNCHRONOUS MOTOR

摘要

FIELD: electric engineering, namely electric machines. ^ SUBSTANCE: method for regulating rotation frequency of asynchronous motor includes changing character of rotating magnetic field. Character of rotating magnetic field is changed by disabling a part of one of motor stator windings from voltage supply to impart elliptic character to a part of magnetic field rotating in the motor. ^ EFFECT: simplification of method for regulating frequency of rotation, reduced costs of method realization. ^ 4 dwg
