Problems solved by technology

[0002] The electric pump includes a stator assembly. Usually, the electric pump will energize the windings in the stator assembly during use. At this time, the windings in the stator assembly will generate electromagnetic waves, which may interfere with other external components. In turn, it may affect the performance of other external components; therefore, how to reduce the interference of the electric pump to the outside is a technical issue that needs to be considered

Abstract

The invention provides an electric pump, which includes a stator assembly, wherein the stator assembly comprises a stator iron core and a winding, the winding comprises a main body segment, a first segment and a second segment, the main body segment is connected with the first segment and the second segment, the stator iron core comprises an iron core tooth part, an iron core yoke part and an iron core neck part, the iron core yoke part is located on the periphery of the winding, a first reference surface is defined, the first reference surface coincides with the axial central axis of the iron core tooth part and the axial central axis of the iron core neck part, the section of the stator assembly is made along the first reference surface, the upper end of the section of the main body segment is flush with the upper end of the section of the iron core yoke part body part, the lower end of the section of the main body segment is flush with the lower end of the section of the iron core yoke part body part, the electric pump further comprises a shielding piece, the shielding piece is made of a conductive metal material, and at least part of the shielding piece is located on the periphery of at least one of the first segment and the second segment. According to the invention, electromagnetic waves radiated to the outside can be reduced, so that interference of the electric pump to the outside can be reduced.

Description

technical field [0001] The present application relates to a fluid pump, in particular to an electric pump. Background technique [0002] The electric pump includes a stator assembly. Usually, the electric pump will energize the windings in the stator assembly during use. At this time, the windings in the stator assembly will generate electromagnetic waves, which may interfere with other external components. In turn, it may affect the performance of other external components; therefore, how to reduce the external interference of the electric pump is a technical issue that needs to be considered. Contents of the invention [0003] The purpose of this application is to provide an electric pump, which is beneficial to reduce the external interference of the electric pump. [0004] In order to achieve the above purpose, one embodiment of the present application adopts the following technical solution: [0005] An electric pump, including a stator assembly, the stator assembly...
