In view of the weakness of the running performance of the induction motor with compound cage rotor( IMCCR) , three types of IMCCR with different rotor structures were proposed. The magnetic field of different rotor structure was analyzed. The starting performance of the three different rotor structure IMC-CR and the leakage inductance of the rotor were calculated. The rotor bar current and loss were analyzed, and the operating performance of three different rotor structure of IMCCR was analyzed. Through the com-parison between the calculation results and the measured results of the starting and running performance, the results show that the calculation results can satisfy the needs of engineering practice. The analysis re-sults show that for the rotor of the compound guide bar and cast aluminum guide strip alternating IMCCR, efficiency and power factor is increased to a greater extent than that of all composite conductive IMCCR. It provides reference for the optimization design of the motor.
