Plastic-packaged stator assembly, plastic-packaged motor with the same, and fluid driving device

Abstract

The invention discloses a plastic-packaged stator assembly, a plastic-packaged motor with the same and a fluid driving device. The plastic-packaged stator assembly is composed of a stator assembly, aplastic packaging element, and an external connection part. The stator assembly consists of a stator iron core, a stator winding and a stator connection part; the stator winding winds around the stator iron core; and the stator connection part is connected with the stator winding electrically. The plastic packaging element is arranged at the stator assembly in a plastic packaging manner; an open part is arranged at the plastic packaging element; and the stator connection part is arranged at the open part. The external connection part is connected with the stator connection part. According to the plastic-packaged stator assembly, wire leading is carried out after plastic packaging completion, so that a placing order of the leading-out wire in the prior art is reduced and dislocation of theleading-out wire is avoided; the assembling process becomes simple; the plastic packaging efficiency is improved; and the plastic packaging yield is increased.

Description

technical field [0001] The invention relates to the technical field of fluid drive devices, and more specifically, to a plastic-encapsulated stator assembly, a plastic-enclosed motor and a fluid drive device. Background technique [0002] Traditional motors generally use iron shells or cast aluminum end covers. Due to the diverse installation structures of fan motors, it is necessary to use plastic packaging technology instead of iron shell technology to realize the diversification of motor structures. The plastic-encapsulated motor is made of thermosetting material, and the overall noise of the motor is low. [0003] In the related technology, the lead wires of the plastic-encapsulated motor come out directly during injection molding. During the injection molding process, it is necessary to increase the process of arranging the lead wires, which will reduce the efficiency of injection molding. It needs to be above 120 degrees, and the insulation layer of the corresponding ...

AI Technical Summary

Problems solved by technology

[0003] In the related technology, the lead wires of the plastic-encapsulated motor come out directly during injection molding. During the injection molding process, it is necessary to increase the process of arranging the lead wires, which will reduce the efficiency of injection molding. It needs to be above 120 degrees, and the insulation layer of the corresponding lead-out wire should also be made of a material with higher temperature resistance, so the material cost is directly increased

In addition, the installation structure of plastic-encapsulated motors is relatively simple, it is difficult to match a variety of structures, and the way of wire passing and winding affects wire breakage, resulting in a low pass rate in the injection molding process.
