开关磁阻电机任意初始位置无反转起动的研究

Switched Reluctance Motor Start Without Inversion at Arbitrary Initial Position and Running

针对有位置传感器开关磁阻电机起动时易出现紊乱,而无法正常运行的现象,提出任意初始位置无反转起动运行实现方案。依据相电感增大能够提供电动转矩的特性,通过位置传感器的输出状态判定转子初始位置区间,确定区间内电感增大相和通电相,确保转子朝单一方向起动。通过实验实现了无反转起动运行,并证实了该方案的可行性和稳定性,可在有起动性能要求的开关磁阻电机控制系统中得到应用。

It is prone to disorder and can not properly run when switched reluctance motor starts. To solve this problem, an implementation scheme was proposed in order to achieve an arbitrary initial position start without inversion. According the characteristic of that the increased phase inductance can provide electric torque, it can be ensured the motor a single direction start. The specific approach was first to determine the initial position interval by the rotor position sensor output state , and then confirmed the increased induct- ance phase and which phase to energize. The no reverse start running was experimentally confirmed and had a favorable stability. It can been applied in the case of start-up performance requirements for switched reluctance motor speed control system.
