【摘要】：多相绕组不同于三相绕组之处是其具有绕组组合的灵活性,确定多相电机定子绕组组合模式则为电磁设计的前提条件。根据多相电机的运行要求,选择对称三相绕组为多相整流发电机定子绕组的基本组成单元,对称四相或五相绕组为变频器供电多相电动机定子绕组的基本组成单元。针对多相电机相数为偶数或奇数、定子绕组半对称与全对称结构4种组合模式,分别进行磁动势分析与定子参数分析。结果表明,在电机相数为偶数时,半对称组合模式比全对称组合模式更有利于消除空间谐波磁动势;而在电机相数为奇数时,半对称组合模式与全对称组合模式在消除空间谐波磁动势方面没有区别,两种模式下稳态定子参数也相等。分析结果为多相定子绕组组合模式的选定提供了依据。
[Abstract]:The reason why the multi-phase winding is different from the three-phase winding is that it has the flexibility of winding combination, and determining the stator winding combination mode of multi-phase motor is the precondition of electromagnetic design. According to the operation requirements of the multiphase motor, the symmetrical three-phase winding is selected as the basic component unit of the stator winding of the multi-phase rectifier generator, and the symmetrical four-phase or five-phase winding is the basic component unit of the stator winding of the inverter powered multiphase motor. In view of the even or odd phase number of multiphase motor and the four combination modes of semi-symmetric and fully symmetric stator windings, the magnetodynamic potential and stator parameters are analyzed respectively. The results show that when the phase number of the motor is even, the semi-symmetric combination mode is more advantageous to eliminate the spatial harmonic magnetodynamic potential than the fully symmetric combination mode, but when the motor phase number is odd, There is no difference between the semi-symmetric combined mode and the fully symmetric combined mode in eliminating the spatial harmonic magnetodynamic potential, and the steady-state stator parameters are equal in the two modes. The results provide a basis for the selection of multiphase stator winding combination mode.
