摘要
基于直流电机电枢绕组支路个数多且相互并联的特点,先使用绕组函数法计算电枢绕组各支路自感、互感,然后根据实际连接关系推导出电枢绕组自感及与其他绕组间互感,以此计算ZD 115型脉流直流电机的电感参数,并考虑了漏抗参数的影响。建立了该电机的有限元模型,其结果表明,绕组函数法与有限元法吻合较好。
According to the characteristics of DC motor,which has multiple armature winding branches connecting in parallel,the self and mutual inductances of each branch are calculated firstly by WFA （Winding Function Approach） and the self inductance of armature winding and its mutual inductance with other windings are then derived according to the actual connections. Inductance parameters of ZD 115-type pulsing current DC motor are calculated with the consideration of leakage reactance parameters. Its finite element model is presented and results show that WFA tallies with the finite element method well.
