Abstract

A new squirrel-cage rotor structure induction motor (IM) that has a auxiliary permanent magnet (PM) rotor and improved cage-rotor structure is presented to enhance the inherent power factor of the IM, and a prototype motor is fabricated by modifying the rotor of a conventional three-phase four-pole squirrel-cage induction motor. The flux linkage, flux distribution, power factor, core loss and efficiency of the novel and conventional rotor structure induction motor are comparative analyzed. The 2D transient finite element analysis method is used for computation the characteristics of the two induction motors.
