Problems solved by technology

This patent adopts the clutch device of electromagnetic clutch principle, which has the advantages of small size and convenient operation. However, because its clutch device 131 is located between the rotor and the lower part of the bearing housing 130, the whole is located inside the motor. In the washing machine with harsh environment, and the motor is a non-sealed structure, the coupling 133 in the electromagnetic clutch device is easily eroded by water and other impurities, thus easily leading to clutch failure. The electric motor itself generates heat due to the energized stator coil winding, which causes the pull-in voltage required by the electromagnetic clutch device to be too high. Since the pull-in voltage is preset, it is easy to cause clutch failure; in addition, because the coupling described in this patent 133 collides with the bearing shell 130 when it moves upwards, which not only produces obvious noise, but also in the washing condition, because the coupling 133 and the bearing shell 130 are only fixed by mutual friction, not only the fixation is unstable, And the coupling part 133 and the bearing shell 130 that are in contact with each other and rubbing against each other experience a long period of mutual wear and tear, resulting in a short service life.
