Problems solved by technology

[0002] In the past, when producing motors, because the motors also required various technical requirements such as heat resistance, heat dissipation, electrical insulation, and impact resistance, they had to use multiple processes such as metal shell protection, internal coil impregnation insulation, etc., and the production process was relatively complicated.
Moreover, this kind of motor has heavy weight, serious noise, and unsatisfactory insulation.

Abstract

The invention discloses an entire packaging structure for a stator component of an external rotor electric machine. The structure comprises an electric machine stator core, package plastic of a thermoplastic or thermosetting insulation material on the electric machine stator core, an electric machine winding wound around the package plastic, a stator insertion piece inserted into the package plastic and connected with the tail end of the electric machine winding, and an electric machine metal shell assembled together with the stator core. The insulation material is packaged in a clearance zone by means of the injection molding process, and a packaging solid body is formed between the package plastic, the electric machine winding and the metal shell. A zone I and a zone II are formed through the injection molding of the insulation material, the zone I is used for accommodating a thermal protection component of the electric machine, and the zone II is used for accommodating a Hall sensor of the electric machine. The structure has the advantages that the strength, precision, high-temperature and high-pressure resistance, and water and damp resistance of the electric machine can be improved, temperature rise and noise of the electric machine are reduced, and normal work of the thermal protector of the electric machine and effective positioning of the Hall sensor of the electric machine are ensured.

Description

technical field [0001] The invention relates to the overall encapsulation of a motor, mainly an overall encapsulation structure of a stator part of an outer rotor motor. Background technique [0002] In the past, when producing motors, because the motors also required various technical requirements such as heat resistance, heat dissipation, electrical insulation, and impact resistance, multiple processes such as metal shell protection and internal coil impregnation insulation had to be used, and the production process was relatively complicated. Moreover, this motor has heavy weight, serious noise, and unsatisfactory insulation. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an overall encapsulation structure of the outer rotor motor stator parts with reasonable structure and good sealing performance. [0004] The purpose of the present invention is achieved through the following technic...
