摘要
永磁同步电动机起动时如果知道转子的初始位置,起动将会十分简便。但是,永磁同步电动机的转子初始位置确定或估计一直是个难题。在研究电动机静起动转矩的基础上提出了一种新的起动策略,较好地解决了在转子初始位置未知情况下电动机的起动。此方法不需要依赖电机的任何参数,而且方法简单。理论分析和实验结果均表明此方法是可行的。
It is easy to start the permanent magnet synchronous motor (PMSM) when knowing the initial rotor position. Unfortunately, the initial rotor position estimation at standstill state of the PMSM depends on the motor parameters and is relatively difficult. Based on the analysis of the static starting torque, a novel motor start strategy is proposed in this paper, which can realize motor starting under initial rotor position unknown instance. The scheme is simple and independent of the motor parameters, theoretic analysis and experimental results have proved its validity.
