摘要
永磁同步电机采用永磁体励磁,只要其旋转就会在电机端产生反电势。根据永磁同步电机的该特点及轨道交通对牵引系统带速度重新投入功能的需求,文章提出了两种基于无位置传感器的永磁同步电机带速度重新投入控制算法,详细推导了其理论基础,并给出了实现方法,并且对第二种控制算法进行了试验验证。
On the basis of permanent magnet excitation, EMF will be generated in the terminal of permanent magnet synchronous motor as long as the motor rotates. According to the characteristics of PMSM and the requirements of rail transit on re-starting of traction system, two calculation methods of re-starting with speed of PMSM based on the sensor-less are proposed. The theoretical basis is derived in detail, the realization methods are given and experimental verification is carded out for the second method.
