摘要
介绍了采用电流变化率法检测永磁同步电机转子磁场初始位置的原理和实现方法,并给出了转子锁定情况的试验结果。针对此方法的不易操作性,在其基础上给出了两种自动寻优方法以及试验结果,试验结果表明电流变化率法是可行的。
It describes the principle and realization method to detect initial position of rotor magnetic field for permanent magnet synchronous motor with current change rate, and the experimental results in the locked rotor case are given. Because this method is not easy to implement, two automatic optimization methods are given as well as the experimental results, which indicates that current change rate method is feasible.
