Combined stator with insulating skeleton

Abstract

The invention discloses a combined stator with an insulating skeleton. The combined stator comprises an expansion sleeve, an iron core unit, the insulating skeleton, a coil wound on the insulating skeleton, and an iron core connecting part which is connected with the iron core unit. The combined stator is characterized in that the iron core unit is shaped like T, and two sides of the T-shaped ironcore unit are provided with mortise grooves; both sides of the iron core connecting part are bulged to be provided with tenons; the exterior of the insulating skeleton is provided with an annular groove; the coil is wound in the annular groove of the insulating skeleton, and the mortise grooves below the T-shaped iron core unit and the tenons of the iron core connecting part are connected; a plurality of T-shaped iron core units and the iron core connecting part form an annular stator through the cooperation of the mortise grooves and the tenons; the inner hole of the annular stator is in interference connection with the expansion sleeve. Compared to the prior art, the stator has an integral insulating skeleton, adapts to standard winding machine operation, is suitable for mass production, and has a good insulating effect. There is no risk that an enameled wire will cause a damage during winding.

Description

technical field [0001] The invention relates to a permanent magnet synchronous motor and a generator with an outer rotor structure, especially the field of low-speed and multi-pole motors. Background technique [0002] In order to improve material utilization and reduce production costs, the split stator core has been used in the field of motors. Usually, the split stator core is in the shape of an "I". When winding, the two separate coil bobbins are first Insert the waist of the "I"-shaped iron core, and form an insulating skeleton with an annular groove after combination, and then wind it together with the iron core to form a separate stator unit assembly, for example: the technology disclosed in Chinese patent CN201710517833.9, the solution exists The issue is: [0003] 1. Since the "I"-shaped iron core insulation frame is composed of two halves, manual work is required, and the efficiency is low; [0004] 2. The coil skeleton and the iron core are wound together, and t...

Problems solved by technology

[0003] 1. Since the "I"-shaped iron core insulation frame is composed of two halves, manual work is required, and the efficiency is low;

[0004] 2. The coil skeleton and the iron core are wound together, and the winding machine needs to be customized, which is inconvenient to produce;

[0005] 3. Winding together with the iron core, it is easy to cause the enameled wire to collide with the iron core during winding and cause damage risk
