Zusammenfassung: | The invention discloses a moving magnet type linear motor module and an elevator door motor, the module comprises a shell, a stator assembly and a rotor assembly, the stator assembly comprises a silicon steel sheet, a coil and a Hall sensor, and the Hall sensor is located in the middle of the stator assembly; the mover assembly comprises magnetic steel and a movable sliding block, the movable sliding block drives the magnetic steel to reciprocate in the horizontal direction relative to the stator assembly, and in the moving process, the Hall sensor of the stator assembly reads the magnetic field change of the magnetic steel at the corresponding position on the mover assembly to obtain the position and the moving speed of the mover assembly. The moving magnet type linear motor module is adopted to directly drive the car door to be opened and closed, the structure is simple, the transmission efficiency is high, modularization is easy, a motor wire of the motor module does not move along with the car door, a dra |
