摘要
提出了一种检测无位置传感器开关磁阻电机(SRM)起动前转子初始位置的方法。通过向电机定子相绕组注入瞬时测试脉冲,跟踪相电流判断转子的初始位置及相应的初始导通相,从而实现转子处于任何位置时的无反转起动。通过对一台8/6极的开关磁阻电机的实验,验证了该方法的可行性。
A method which detected the rotor initial position and decided the relevant starting phase was proposed, through tracking testing currents from the injected testing pulse into stator phases of position sensorless SRM to realize the start of SRM without reversing no matter the rotor at any position, and it was proved by theoretical analysis and also demonstrated by experiment of SRM (8/6).
