要約(英語): Recently, global warming and the problem with successfully incorporating environmental safeguards have promoted the need for a more power-efficient motor. Therefore, as a driving source, permanent magnet synchronous motor (PMSM) with concentrated winding is widely used as the important device for a variety of fields. However, a PMSM with concentrated winding generates more vibrations than that with distributed winding because of a radial electromagnetic force. This paper describes the influence of a new skewed rotor on the characteristics of a concentrated winding PMSM. We investigated the influence by using a three-dimensional finite element analysis (3-D FEM) and several measurements. In addition, we presented that the proposed rotor is effective in reducing the radial electromagnetic force without decreasing the motor efficiency.
