Abstract

The invention discloses a stator assembly and a manufacturing method thereof. The stator assembly comprises a stator core, and a coil winding which is installed at the end part insulation of the stator core and winds the end part insulation. The stator core comprises a yoke part and tooth parts projecting from the inner side of the yoke part. The end part insulation comprises insulation yoke parts and insulation tooth parts which sleeve the tooth parts. The insulation tooth parts sleeve the tooth parts. The insulation yoke parts sleeve the yoke part. The end part insulation also comprises a plurality of positioning ribs which are raised from the outer side of the yoke part and are connected to the insulation yoke parts. The outer sides of the positioning ribs are provided with axial inclined planes. The stator assembly has the advantages of a simple structure and convenience in manufacture, the stator core can be protected by the positioning ribs, the axial inclined planes of the positioning ribs play a good positioning role in the plastic sealing or installation of the stator assembly.

Description

Technical field: [0001] The invention relates to a stator assembly and its manufacturing method. Background technique: [0002] The existing stator assembly includes a stator core, end insulation mounted on the stator core, and coil windings wound on the end insulation, the stator core includes a yoke and teeth protruding from the inside of the yoke, the The end insulation includes an insulating yoke, the insulating tooth is nested on the tooth, and an insulating yoke is nested on the yoke. This kind of stator assembly often has the following disadvantages: due to the inconvenient positioning of the stator core during plastic packaging or installation, there are large individual differences in the performance of the motor. Invention content: [0003] The purpose of the present invention is to provide a stator assembly and a manufacturing method thereof, the stator assembly is easy to locate and has consistent performance. [0004] The purpose of the present invention is ...
