摘要
介绍了永磁材料的发展、现状及永磁同步电动机的转子结构,并就永磁同步电动机在电梯中应用时遇到的短时过我问题和去磁问题进行了探讨,提出了相应的解决方法。
This paper introduces the development and present condition of permanent-magnet materials as well as the construction of permanent-magnet synchronous electric motors. It inquires into the problem of short-time overload and magnet degeneracy in the application of permanent-magnet synchronous electric motors to elevators and puts forward relevant solution.
