摘要
针对内置式永磁同步电机,研究了一种减小其齿槽转矩的方法,着重分析了气隙磁密与齿槽转矩的关系。通过优化设计气隙磁密的特定次谐波来减小齿槽转矩,利用有限元软件Ansoft仿真分析比较不同的优化方案。样机试验表明,所述方法能有效减小电机的齿槽转矩。
For the interior permanent magnet motor,a method of reducing the cogging torque was studied,the relationship of air gap flux density and the cogging torque was analyzed emphatically. The cogging torque was reduced by optimizing and designing some specific harmonic of air-gap flux density. The different optimization projects were compared by using finite element software Ansoft. The prototype experiments show that the described method can effectively reduce the cogging torque of the motor.
