Abstract :
This paper describes modeling and performance analysis of canned motors, which are developed as drivers for ammonia compressors. The motor has a metallic can inserted in the air gap of a cage induction motor. The characteristics such as eddy current loss and distributed electromagnetic force in the can are calculated by the combination of 2D and 3D finite element methods. The variation of the performance of the motor due to the can is also clarified
