Electromagnetic Shielding Analysis of a Canned Permanent Magnet Motor

The use of metallic cans in airgap forms an electromagnetic shielding phenomenon that characterizes a canned electrical motor. Imposed in alternating airgap flux field, cans induct strong and distributive eddy current, the fundamental feature that interacts original flux and determines output features. In particular that induction leads to additional can-shielding loss that is considerably much hi...
