摘要:
针对内置式永磁同步电机存在的齿槽转矩问题,采用有限元软件Maxwell分别对不同分段数、不同非均匀气隙情况下的内置式永磁同步电机进行分析.理论分析表明:转子分段斜极可以抑制齿谐波,从而削弱齿槽转矩;而采用非均匀气隙结构则可以通过优化气隙磁密的特定次谐波削弱齿槽转矩.依据理论分析,提出一种二者相结合的方法抑制电机的齿槽转矩.优化结果表明:该方法能有效地抑制电机的齿槽转矩.
Abstract:
In order to solve the issues on cogging torque of interior permanent magnet synchronous motor(IPMSM), the IPMSMs with different segments and non-uniform air gap were analyzed using the finite element software Maxwell in this paper. Theoretical analysis showed that teeth harmonics can be effectively reduced by step skewing of rotor, which leads to the decrease of cogging torque; meanwhile, the cogging torque can also be minimized by introducing the non-uniform air gap based on specific harmonic of optimal gap flux density. On the basis of the theory analysis, a combined method is proposed to eliminate the cogging torque of IPMSM. Optimization results verify the described method can effectively reduce the cogging torque of the IPMSM.
