Embodiment 1

[0023] Embodiment one: according to Figure 1-2 As shown, a plastic-sealed motor for a washing machine includes a rotating shaft 1, a rotor assembly 2, a plastic-sealed stator assembly 3 and an end cover 4. The plastic-sealed stator assembly 3 includes a stator core 31, a stator winding 32 and an injection molded casing. The rotor assembly 2 is installed on the shaft Above 1, the plastic-sealed stator assembly 3 is nested outside the rotor assembly 2, and the two ends of the plastic-sealed stator assembly 3 are equipped with end covers 4, the end cover 4 includes a front end cover and a rear end cover, and a bearing chamber 41 is installed in the bearing chamber. 5, its bearing 5 is a ball bearing.

[0024] The plastic-sealed stator assembly 3 and the rear end cover are molded and sealed into an integrated plastic-sealed stator by molding with a plastic sealing material mold, which effectively ensures the coaxiality of the rear end cover bearing chamber 5 and the inner diamete...

Embodiment 2

[0027] Embodiment two: according to Figure 5-6 As shown, the difference from the above embodiment is that the bearings 5 ​​in the front end cover and the rear end cover are oil-impregnated bearings, and both the front end cover and the rear end cover are provided with bearing clips 44 for installing the oil-impregnated bearings. Compared with ball bearings, oil-impregnated bearings have the advantages of low cost, vibration absorption, and low noise, thereby reducing the noise generated when the motor is running.

Abstract

The invention relates to the field of motor processing, in particular to a plastic package motor for a washing machine. The plastic package motor comprises a rotating shaft, a rotor assembly, a plastic package stator assembly and end covers, wherein the plastic package stator assembly comprises a stator iron core, a stator winding and an injection molding case, the rotor assembly is arranged on the rotating shaft, the plastic package stator assembly is nested outside the rotor assembly, the two ends of the plastic package stator assembly are provided with the end covers, the end covers are provided with bearing chambers, bearings are arranged in the bearing chambers, the end covers comprise a front end cover and a back end cover, and the plastic package stator assembly and the back end cover are formed into an integral plastic package stator via a plastic package material mold through molding pressing plastic package. The plastic package motor has the advantages that the plastic sealing stator and the end covers are formed into an integral structure through plastic package, and the waterproof performance of the motor is ensured. During the plastic package, the concentricity of the bearings arranged in the end covers of the two ends of the plastic package stator is ensured through the precision of a plastic package mold, so the vibration during the rotor rotation is reduced, and the generation of noise is reduced.

Description

technical field [0001] The invention relates to the field of motor processing, in particular to a plastic-encapsulated motor for a washing machine. Background technique [0002] At present, ordinary motors used in washing machines are not waterproof, corrosion-resistant, and moisture-resistant, and the life of the motor is not long, resulting in a short lifespan of the washing machine. Compared with ordinary motors, plastic-encapsulated motors have the following advantages: ① Beautiful appearance, small size, light weight, and easy assembly, suitable for mass automated production. ②Low noise. Since the rear end cover and the stator assembly are injected and solidified by the plastic sealing compound to form an integral plastic-sealed stator wire stator, the concentricity of the stator is improved and noise is reduced. ③Small vibration. Because the inner circle of the motor stator iron core, the bearing chamber of the end cover, and the seam are integrally formed b...
