摘要
位置检测精度对永磁无刷直线直流电动机的运行性能有重要影响。实验中发现由霍尔传感器产生的换相距离并不一致,且受其他因素的干扰。因此提出了一种无刷直线直流电动机动子位置检测的方法,采用霍尔元件和光电开关管相结合的方式,提高了定位和测速精度,增加了硬件冗余,提高了可靠性。实验证明,该方法原理简单,灵活实用。
The position detection precision has very important influence on the permanent magnetic brushless linear DC motorg （PMBLDCM） behavior. From the experiment,it is found the phase - changing distance produced by the Hall sensor can＇t keep consistent which influenced by other factors. A method of rotor position detection for PMBLDCM is presented, Hall sensor and photo - electrical switch are combined to improve precision of position and speed of rotor. It increases the hardware redundancy and improves reliability. It is showed by the experimentation that the method is flexible and useful.
