内置式永磁电机齿槽转矩的优化设计
Optimal Design of Cogging Torque of Interior Permanent Magnet Motor
摘要
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 ele-ment software Maxwell in this paper.Theoretical analysis showed that teeth harmonics can be effectively re-duced 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.关键词
