    • A method of controlling an electrical machine that includes selecting an edge of a rotor-position signal as a reference edge and commutating a phase winding of the electrical machine at times relative to the reference edge. The rotor-position signal has at least four edges per mechanical cycle, each of the edges being associated with a respective zero-crossing in back EMF or minimum in inductance of the phase winding. The angular position of at least one of the edges relative to its respective zero-crossing or minimum is different to that of the other edges. The reference edge is then selected from the edges such that the angular position of the reference edge relative to its respective zero-crossing or minimum is the same with each power on of the electrical machine. Additionally, a controller and control system that implement the method.
    • 一种控制电机的方法,包括选择转子位置信号的边缘作为参考边缘,并且相对于参考边缘在时间上整流电机的相绕组。 转子位置信号每个机械循环具有至少四个边缘,每个边缘与反向电动势中的相应过零点或相绕组的电感中的最小值相关联。 边缘中的至少一个相对于其相应过零点或最小值的角位置不同于其它边缘的角位置。 然后从边缘中选择参考边缘,使得参考边缘相对于其相应的过零或最小值的角位置与电机的每个上电相同。 另外,实现该方法的控制器和控制系统。

    • A method of controlling a brushless motor that includes rectifying an alternating voltage to provide a rectified voltage, and exciting a winding of the motor with the rectified voltage. The winding is excited in advance of predetermined rotor positions by an advance period and is excited for a conduction period over each electrical half-cycle of the motor. The length the advance period and/or the conduction period is defined by a waveform that varies periodically with time. The method then includes adjusting the phase of the waveform relative to the alternating voltage in response to a change in one of motor speed and RMS value of the alternating voltage. Additionally, a control system that implements the method, and a motor system that incorporates the control system.
    • 一种控制无刷电动机的方法,包括整流交流电压以提供整流电压,以及激励具有整流电压的电动机的绕组。 绕组在预定的转子位置之前提前激励,并且在电动机的每个电半周期上被激励以导通周期。 前进周期和/或导通周期的长度由随时间周期性变化的波形限定。 该方法然后包括响应于电动机速度和交流电压的RMS值中的一个的变化来相对于交流电压调整波形的相位。 另外,实现该方法的控制系统以及并入控制系统的电机系统。
