摘要
为分析不同永磁体层数与定子槽数的作用效果,探究了具有多层永磁体结构的内置式分数槽集中绕组永磁同步电机的性能,设计并制造了9槽10极与18槽10极电机的仿真模型与原型机,采用有限元软件分析了不同永磁体层数与定子槽数对电机输出转矩、齿槽转矩、气隙磁密和齿部磁饱和等电磁特性的影响。理论分析及实验结果均表明,相比于9槽10极,18槽10极电机可以更好地抑制转矩脉动并提升平均输出转矩,同时,双层永磁体电机相比单层永磁体电机具有更优异的性能。
To analyze the effects of permanent magnet of different layers and stator of different slot numbers,this paper investigated the properties of multilayer interior permanent magnet synchronous machines with fractional-slot concentrated windings(FSCWs).This paper designed 9-slot/10-pole and 18-slot/10-pole IPM machines with multilayer permanent magnets and built a prototype to verify the simulation results.The analysis data came from the finite element software,which reflected the effects of the slot number and the number of magnet layers on the rated torque,cogging torque,air gap flux density,tooth saturation and other electromagnetic characteristics.Theoretical analysis and experimental results show that the 18-slot/10-pole machines perform better in suppressing the ripple torque and improving the average torque.Besides,the double layer machines have a better performance than its single layer counterparts do.
