The invention discloses an elevator permanent magnet motor based on frequency converter control and a using method thereof, and relates to the technical field of elevator permanent magnet motors, the elevator permanent magnet motor comprises a motor shell, a rotor and a U-shaped limiting frame, a rotor magnet yoke is installed on the outer side of the rotor, neodymium iron boron permanent magnets are installed on the inner sides of embedded arc grooves, and the U-shaped limiting frame is arranged on the inner side of the rotor magnet yoke. The connecting frame is installed on the outer side of the U-shaped limiting frame. According to the invention, the inner side of the rotor magnet yoke is provided with the loosening protection assembly, the neodymium-iron-boron permanent magnet falls off from the inner side of the embedded arc groove due to the failure of the adhesive in the use process of the permanent magnet motor, and the separation limiting disc blocks the neodymium-iron-boron permanent magnet so as to prevent the neodymium-iron-boron permanent magnet from sliding off from the inner side of the rotor magnet yoke. When the neodymium-iron-boron permanent magnet is in contact with the contact type sensor, the maintenance alarm unit works, the problems of abnormal motor operation, chamber sweeping and the like caused by the fact that the magnetic steel falls off from the neodymium-iron-boron permanent magnet are solved, the safety and reliability of an elevator are improved, and the service life of the elevator is prolonged.
本发明公开了一种基于变频器控制的电梯永磁电机及其使用方法,涉及电梯永磁电机技术领域,包括电机壳体、转子和U型限架,所述转子的外侧安装有转子磁轭,所述镶嵌弧槽的内侧安装有钕铁硼永磁体,所述U型限架设置在转子磁轭的内侧,所述连接架安装在U型限架的外侧。本发明通过在转子磁轭的内侧设置有松脱防护组件,永磁电机使用过程中由于胶粘剂失效钕铁硼永磁体会从镶嵌弧槽内侧脱落,限脱盘对钕铁硼永磁体进行阻挡防止钕铁硼永磁体从转子磁轭内侧滑落,钕铁硼永磁体与接触式传感器接触时检修报警单元工作,防止磁钢脱落钕铁硼永磁体造成电机运转不正常,产生扫膛等问题,提高电梯的安全性和可靠性,延长了电梯的使用寿命。
