摘要
多相电机参数的分析和计算对电机的设计和控制有重要意义。以绕组均匀分布的多相异步电机为例,根据多相电机定转子的实际结构,利用绕组函数法,求解了相坐标系下的电机参数;并在此基础上建立了旋转坐标系下多相电机的数学模型,推导了多相电机各d-q平面内的参数,尤其是各平面内定子激磁电感和谐波漏感、转子电阻和漏感等。分别采用解析法、有限元法以及实验测量方法计算了一台9相异步电机的参数,并以此验证该电机参数表达式的正确性。
Analysis and calculation of motor parameters help to design and control of a multiphase motor.This paper presented the analysis and calculation of parameters of a multiphase induction motor.Taking into account the actual structure of stator and squirrel cage rotor,the motor parameters in phase coordinate were calculated using winding function method,based on which the mathematical model of n-phase p-pole-pair induction motor is built up.Motor parameters in different d-q planes,including magnetizing inductances,harmonic leakage inductances,rotor resistances and leakage inductances,were deduced.Taking a 9-phase induction motor as an example,the motor parameters were calculated by analytical method,FEA （finite element analysis） method and experimental measurement respectively.The agreement between analytical results and other results verifies the analytical expression of the multiphase motor parameters.
