摘　　要： 针对有位置传感器的无刷直流电机需要位置传感器提供换相信号的问题,提出了基于磁势确定霍尔传感器安装位置的方法。霍尔传感器通过检测转子磁势确定转子位置,产生传感器信号控制定子绕组换相,使得定、转子磁势相位差在60°~120°之间波动,从而使电机输出最大力矩。通过实验测得使用该方法进行霍尔传感器位置安装的无刷直流电机的输出力矩波形与理论一致,从而验证了此方法正确可行。 This article proposes a method to determine Hall sensors location by the Magnetic Motive Force(MMF)of the motor,for the question of BLDC motor requiring position sensors to provide tri-winding signals.Hall sensors determine the rotor position by sensing the rotor magnetic potential,and generate a signal to control the stator winding current commutation.The phase difference between the rotor and the stator magnetic potential can be established between60 to 120 degrees so that the motor can produce the maximum torque.The output torque waveform of the BLDC motor,whose hall sensors are installed using this method by experiment,is the same with the theoretical one,which proves that this method is correct and effective.
