[0005] Wherein, the synchronous motor winding is a sealed and waterproof structure.

[0006] Wherein, the synchronous motor winding is in a ring shape, and the corresponding synchronous motor permanent magnet also forms a ring shape.

[0007] Wherein, the roller is provided with a suspension permanent magnet, and a magnetic suspension electromagnet is provided in the shell at the corresponding position, and the roller can be suspended by control.

[0008] There are two groups of suspended permanent magnets, located on both sides of the drum; and two groups of corresponding magnetic suspension electromagnets are provided.

[0009] Wherein, the suspension permanent magnets are combined into a ring shape, and the corresponding magnetic suspension electromagnets are also combined into a ring shape.

[0010] Wherein, the magnetic levitation electromagnet is a sealed and waterproof structure.

[0011] Wherein, guide and limit permanent magnets are arranged on both sides of the roller, and limit electromagnets are arranged in the corresponding position shell.

[0012] There are two groups of guide and limit permanent magnets, located on both sides of the drum; there are also two groups of corresponding limit electromagnets.

[0013] Among them, the guiding and limiting permanent magnets are combined into a ring shape, and the corresponding limiting electromagnets are also combined into a ring shape.

[0014] Wherein, the limit electromagnet is a sealed and waterproof structure.

[0015] Wherein, the drum can rotate in forward and reverse directions.

[0016] The magnetic suspension drum washing machine of the present invention uses a permanent magnet installed on the outer wall of the drum as the rotor of the motor and a synchronous coil winding installed on the inner wall of the shell as the stator of the motor. The forward and reverse rotation of the drum can be controlled. At the same time, magnetic suspension systems are installed at both ends of the drum to ensure that the drum remains in a suspended state during operation. Limiting systems are installed on both sides of the drum to control the guidance of the drum to ensure that the drum does not collide with the inner wall of the shell during rotation.
