The stator Can and rotor Can are unique structures in double canned induction motors, and Can losses include Can eddy current losses and Can circulating current losses between the Can and other end structures. However, the current research of Can losses is mainly focused on Can eddy current losses, and operation conditions are limited to the no‐load condition, rated‐load condition and start condition. Aiming at this problem, two kinds of Can losses are calculated and analysed in details. The influence factors are researched. Based on this, a reduction method of Can losses is proposed, and the efficiency curve is provided. Calculation results are compared with test values to validate the accuracy of the solving model. The reliable basis is provided for reducing Can losses in double canned induction motors.
