Abstract
<p>The rotor of the permanent magnet synchronous motor (PMSM) consists of one yoke and multiple permanent magnets (PMs) embedded in it, and their design greatly affects performances of the PMSM. It is desirable to concurrently optimize the PM layout and the topology of the yoke structure. However, it is known that the concurrent optimization is difficult, whereas it is relatively easy to solve the respective optimization problems independently. In this paper, we assume ahierarchy for the PMSM optimization problem, and propose to incorporate a topology optimization method for determining the yoke structure and the response surface methodology for determining the PM layout. First, the yoke structure is optimized under several PM layouts using the topology optimization method. Second, on the basis of these results, the response of the PMSM performance is approximated by the response surface methodology, and then the layout of the permanent magnets is optimized. Finally, topology optimization is performed for the yoke structure under the condition of the optimized layout. The effectiveness of the method is shown by a numerical example.</p>
