摘要
深入讨论了单元电机的槽号相位图的5个特点。分析并给出了分数槽绕组单元电机的4个约束条件和分数槽集中绕组单元电机的2个附加约束条件。讨论了分数槽集中绕组单元电机的绕组系数的计算方法,并利用虚拟电机的概念给出了分数槽电机与整数槽电机绕组分布系数计算时的等效条件。因采用了槽号相位图进行分析与计算,分析方法有利于计算机自动化分析和选配绕组方案。
Five features of slot number-phase table of cell motor were deeply discussed in this paper. Then it was derived that four constraints of cell motor with fractional slot winding and two additional constraints of cell motor with concentrated fractional slot winding. Finally, the equivalent calculation of spread factor of fractional slot motor and integral slot motor was proposed by use of the dummy motor. Because Slot numberphase table was brought in, the method proposed by this paper was convenient to carry out automatic analysis and calculation by computer.
