Motor and washing machine with same

Abstract

The invention relates to a motor and a washing machine with the same. The motor includes two or more stator sets and at least one rotor set. The rotor is provided with steel magnets respectively corresponding to two or more stator sets. The washing machine includes a casing; and a water cylinder, a roller and the above motor that are disposed in the casing. The water cylinder is a fixed part, andthe roller is a rotating part. The rotor of the motor and the roller are connected through a rotating shaft. The stators of the motor are fixed on the water cylinder. The rotating shaft is provided with at least two bearings, and a portion, which cooperates with the rotating shaft, of the rotor of the motor is located between the two bearings. The technical scheme of the invention can not only improve the driving torque of the motor, thereby increasing the capacity of washing clothes in the washing machine, but also reduce the noise and prolong the service life of the washing machine.

Description

technical field [0001] The invention relates to the field of motor equipment, in particular to a motor and a washing machine with the motor. Background technique [0002] Such as Figure 23 As shown, the existing drum washing machine generally mainly includes: a water drum 2 for containing washing water; a drum 3 for accommodating clothes and rotatably placed inside the water drum 2; a motor 4 for providing power to rotate the drum 3; a housing 1 , for accommodating components such as the water cylinder 2 and the motor 4. [0003] For the washing machine of direct drive type, the rotating shaft 6 connected with the drum 3 is connected with the water cylinder 2 through two bearings 8 and 9, and the two bearings 8 and 9 are all placed in a bearing seat 5 fixed at the rear of the water cylinder 2 . The motor 4 includes a rotor 41 and a stator 42 . The stator 42 is fixedly connected with the water cylinder 2, and the rotor 41 is connected with the end of the rotating shaft 6 t...

AI Technical Summary

Problems solved by technology

[0004] In the connection mode of this motor, the rotor 41 is connected to the end of the rotating shaft 6, and the motor connection part on the rotating shaft 6 is often in a cantilever state. 41 The air gap is not uniform, which will affect the operation of the motor; and will generate a large electromagnetic pull and generate noise

[0005] When a lot of clothes to be washed are put into the drum 3, the load on the motor 4 will be increased, and the motor 4 may not be able to provide sufficient power to drive the drum 3 to rotate; and if the motor 4 is in a high-load running state for a long time, it will cause serious heating of the winding. , affecting the long-term reliability of the motor
