Abstract:

A new-type rotor structure to further improve the starting performance of two-phase cage induction servo motor was presented. Through the analyze of two-phase induction servo motor starting performance, characteristics of induction motor rotor and structure, two bars were inserted into the cage. Because of the skin effect, the motor produced a larger starting torque and a smaller starting current at start-up, and the starting performance of the motor was improved. The new-type rotor structure was applied to a two-phase induction servo motor, the simulation and prototype test results show that the new-type rotor structure effectively improves the starting performance of two-phase induction servo motor.

Key words: induction servo motor, rotor resistance, skin effect, starting performance
