Integrally-formed insulating stator

Abstract

The invention discloses an integrally-formed insulating stator which comprises a coil, an iron core and an integrated insulating sleeve. The iron core and the integrated insulating sleeve are integrally formed, and the iron core comprises an outer ring and a plurality of iron core units. The integrated insulation sleeve comprises an insulation periphery and a plurality of extension parts. The extending part is provided with a hollow cavity, and the shape of the hollow cavity corresponds to that of the outer contour of the iron core unit. An insulating groove is formed between every two adjacent extending parts, and the coils are wound outside the extending parts. The end, connected with each extending part, of the insulating periphery is provided with an outer insulating blocking piece protruding outwards, the upper end and the lower end, away from the insulating periphery, of each extending part are each provided with an inner insulating blocking piece protruding outwards, and the outer insulating blocking pieces and the inner insulating blocking pieces are used for limiting separation of the coil. The integrally-formed insulating stator provided by the invention is obtained by integral injection molding of the iron core and the insulation, can solve the problem that insulation damage or incomplete coverage caused by manual operation is broken down, facilitates machine winding, improves the insulation reliability, is stable in quality, and improves the production efficiency.

Description

technical field [0001] The invention relates to the field of iron cores, in particular to an integrally formed insulated stator. Background technique [0002] The iron core insulation of the permanent magnet synchronous motor in the prior art mainly adopts multiple small pieces such as slot wedges (epoxy glass cloth laminated), slot insulation (ester film polyester fiber non-woven soft composite materials) and so on, which must be manually embedded, and The machine cannot complete the process, resulting in cumbersome and time-consuming processes; and the quality and reliability are not consistent, and there will be quality problems such as motor insulation damage. The current insulation is not suitable for machine wire insertion, which limits the development of stator core automatic wire insertion technology, and is not conducive to improving the production efficiency of the motor and reducing the overall cost. Contents of the invention [0003] In order to solve the prob...
