An Approach to Flux Control of Induction Motors Operated with Variable-Frequency Power Supply

Akira Nabae; Kenichi Otsuka; Hiroshi Uchino; Ryoichi Kurosawa

A new speed control system for induction motors has been developed which is capable of controlling with quick field weakening and superior response and stability. This method is to control the stator current as a vector quantity on the basis of slip frequency control. More specifically, it is designed to calculate the commanded stator current of the induction motor by corresponding to flux and torque commands on the basis of motor constants and use the calculated commands to control the stator current.
