Stator insulation framework, stator with stator insulation framework and motor

Abstract

The invention provides a stator insulation framework, a stator with the stator insulation framework and a motor. The stator comprises stator iron cores and windings; the insulation framework comprises upper frameworks and lower frameworks; a first winding groove and a first wire passing groove are formed in each upper framework, and a second winding groove and a second wire passing groove are formed in each lower framework; the first winding grooves and the second winding grooves are used for winding the windings, and the first wire passing grooves and the second wire passing grooves are used for passing through bridging wires of the windings; support frames are formed on the lower frameworks and are used for supporting the bridging wires of the windings; the upper frameworks, the lower frameworks and the stator iron cores are connected through limiting pieces and limiting grooves; when the stator insulation framework is applied to the stator, a plurality of stator iron cores are respectively connected with a plurality of upper frameworks and a plurality of lower frameworks, and the windings are wound in the first winding grooves and the second winding grooves; and the bridging wires of the windings penetrate through the first wire passing grooves and the second wire passing grooves to extend. The invention is simple in structure, easy to operate and high in production efficiency, and the tightness of the bridging wires of the windings is accurately controlled through the support frames of the lower frameworks.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a stator insulating skeleton and a stator and electric motor with the same. Background technique [0002] The motor body is generally composed of stator, rotor, end cover and other components. The stator includes stator core, insulating frame and winding. The insulating bobbins currently used in electric motors have many drawbacks. For example, when the stator is round, the windings in the wire slot are easy to be loose and exposed or stretched to break due to the limitation of the wire routing. [0003] In the patent application number 201520348503.8, a motor insulation frame and a motor with it are proposed, which can improve the above problems to a certain extent; but there are major limitations, and the tightness of the bridge wire can only be adjusted through the depth of the wire slot For a stator with a thin skeleton and a relatively compact stator core structure...
