Abstract

PURPOSE:To preferably control an instantaneous torque of an induction motor by converting the deviation between a magnetic flux instruction and the actual magnetic flux into a slip frequency, adding it to a slip frequency obtained separately and compensating a magnetic flux deviation based on the error slip frequency. CONSTITUTION:A deviation between a magnetic flux instruction from a function generator 18 and the actual magnetic flux from a magnetic flux amplitude arithmetic circuit 16 is obtained, is amplified by a magnetic flux regulator 19, and is applied as an exciting current instruction to a current instruction arithmetic circuit 12. Further, the error slip frequency upon variation in the load of the secondary wire wound resistor of a motor 14 is applied to the slip frequency instruction through a regulating system including a D element.
