Abstract
This paper presents topology optimization of structure in IPMSM (Interior Permanent Magnet Synchronous Motors). In this paper, we aim to obtain IPMSM with high torque. To achieve this goal, we design the rotor structure and state structure of IPMSM using topology optimization. Rotor structure is composed of permanent magnets, silicon steel, and non-magnetic materials. State structure is composed of steel and copper wire. Torque is given depending on the layout of these materials. We provide numerical examples to demonstrate the usefulness of the presented method.
