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 requi...
