摘　　要：本文对永磁同步电机的电感参数特性进行了研究。先是建立了永磁同步电机的在d、q坐标系下的数学模型,并在此基础上推导出了d轴电感L_(d)和q轴电感L_(q)以及电机转矩的计算公式。随后利用有限元法对一台12极54槽的永磁电机的转矩特性进行了计算。结果表明,电机转矩的有限元计算值与基于d、q轴电感的理论计算值基本一致,验证了永磁电机参数计算的有效性,为后续设计电机控制方法提供了重要参考。This paper studies the inductance parameters of permanent magnet synchronous motor.Firstly,the mathematical model of permanent magnet synchronous motor in D and Q coordinate system is established,and on this basis,the calculation formula of inductance L_d of axis D and inductance L_q of axis Q and motor torque is deduced.Then the torque characteristics of a permanent magnet motor with 12 poles and 54 slots are calculated by finite element method.The results show that the finite element calculation value of motor torque is very consistent with the theoretical calculation value based on d and Q axis inductance,which verifies the validity of parameter calculation of permanent magnet motor,and provides an important reference for the subsequent design of motor control method.
