| 摘 要： | 基于永磁同步电机(Permanent Magnet Synchronous Motor,简称PMSM)的数学模型,由数学推导得出PMSM在d,q坐标系下电感参数的理论公式,通过电桥测量电机的静态三相电感和三相电阻参数即可计算得到d,q轴电感和相电阻参数。该方法无需考虑电机永磁转子的当前位置,无需额外测量电路及进行驱动控制,具有理论清晰、测量简单、通用性强等特点。针对PMSM磁链参数,将电机加速到一定转速后通过测量开路电压及转子频率,即可计算获得磁链系数。实验验证了该测量方法的正确性和准确性。

| Abstract: | Based on the mathematical model of permanent magnet synchronous motor(PMSM),theoretical formulae of inductance parameters which are in the d,q coordinate system of PMSM is derived from the mathematical formulae.By measuring static electric three-phase inductance and resistance of PMSM through electrical bridge,inductance and resistance parameters of d,q axis are computed without considering current rotor position.This method has advantages of no extra meaturing circuit for power control,clear theory,easy me... |
