【摘要】：分数槽绕组轴向磁通永磁(AFPM)电机的齿顶漏磁较大。在利用等效磁路计算程序调试电机设计方案时,需要准确计算漏磁系数,而准确计算漏磁系数的前提是准确计算齿顶漏磁系数。根据轴向磁通永磁电机磁通路径的分布特点,针对定子齿和磁极不同的相对位置,给出了不同位置角时的齿顶漏磁解析公式。为了验证解析公式的正确性,以一台电机的设计方案为例,采用解析法和有限元法分别计算漏磁系数,结果表明解析计算结果和有限元计算结果具有较好的一致性。最后给出了齿顶漏磁与电机极数之间的关系,为电机设计和优化提供了参考。
[Abstract]:The flux leakage at the top of the teeth of the axial flux permanent magnet (AFPM) motor with fractional slot winding is larger. When using the equivalent magnetic circuit calculation program to debug the design scheme of the motor, it is necessary to calculate the magnetic flux leakage coefficient accurately, and the premise of the accurate calculation of the magnetic flux leakage coefficient is to calculate the magnetic leakage coefficient of the tooth top accurately. According to the characteristics of flux path distribution of axial flux permanent magnet motor, an analytical formula for magnetic flux leakage at different position angles is given for different relative positions of stator teeth and magnetic poles. In order to verify the correctness of the analytical formula, the analytical method and the finite element method are used to calculate the magnetic flux leakage coefficient respectively, taking the design scheme of a motor as an example. The results show that the analytical calculation results are in good agreement with the finite element calculation results. Finally, the relationship between the flux leakage at the top of the tooth and the number of poles of the motor is given, which provides a reference for the design and optimization of the motor.
