| Abstract |
Interior permanent magnet synchronous motors (IPMSMs) are used in various applications. Because of concerns about environmental problems such as global warming, IPMSMs are investigated to improve the efficiency to save energy. Magnetic steel sheets are commonly used in IPMSMs, and the use of low-iron-loss materials in IPMSMs to improve their performance has recently been examined. In this study, the influence of the iron loss properties of magnetic steel sheets on the loss properties of IPMSMs was investigated. Two different magnetic steel sheets were used in IPMSMs with two different rotor structures. The performance of these models was compared analytically and experimentally. The results indicate that if low-iron-loss materials are used in IPMSMs, the efficiency of the rotor with a large reluctance torque is likely to be high. |
