Problems solved by technology

In the process of the injection plastic entering the mold cavity for curing, due to the structure of the mold, it is impossible to ensure that the temperature of each part of the injection plastic flowing into the mold is the same, that is, during the curing process, the temperature of each area of ​​the injection plastic is different. As a result, the curing area of ​​each area is different. The higher temperature area is faster to cure, and the lower temperature area is slower to cure. As a result, a certain internal stress will be generated inside the injection molding end, causing the risk of fracture. When The vibration generated by the motor during operation will cause aggravated damage inside the injection molding end and affect the overall quality of injection molding

Embodiment Construction

[0029] see in conjunction Figure 1 to Figure 4 As shown, according to the embodiment of the present invention, the motor stator includes a stator core 1 and an injection molded end 2 injection-molded at the end of the stator core 1 , and a skeleton 3 is embedded in the injection molded end 2 .

[0030] Since the embedded skeleton 3 is added in the injection molding end 2, the internal space of the injection molding end 2 can be divided by the embedded skeleton 3, thereby reducing the internal stress between different parts of the injection molding inside the injection molding end 2 and improving the injection molding efficiency. The overall anti-vibration performance of the end ensures the uniform conduction of the winding heat to the outside.

[0031] Preferably, the skeleton 3 is embedded in the injection molding end 2. On the one hand, it can ensure a more uniform division of the inner area of ​​the injection molding end 2, so that the internal stress between different par...

Abstract

The invention provides a motor stator and a motor. The motor stator comprises a stator iron core (1) and an injection molding end part (2) in injection molding at the end part of the stator iron core(1), wherein a frame (3) is embedded at the injection molding end part (2). According to the motor stator of the invention, the internal stress between different parts between injection molding materials inside the injection molding end part can be reduced.

Description

technical field [0001] The invention belongs to the technical field of product packaging, and in particular relates to a motor stator and a motor. Background technique [0002] With the continuous improvement of the quality requirements of the motor, the injection molding of the stator inside the motor has gradually become a trend. The overall structural strength, vibration resistance, electrical insulation and heat dissipation can be improved by injection molding the motor stator. [0003] The injection molding of the stator needs to design the corresponding mold, and pour the corresponding injection molding material into the area that needs to be injected. After injection molding, the slot and end area of ​​the stator will be filled with the injection molding material. [0004] Ordinary injection molding will fill the stator slot, and the end of the stator will be injection molded on one side or on both sides depending on the process. [0005] The injection molding end of...
