The insulating structure is used for a toothed part of a stator assembly and comprises a main body and an insulating board, wherein the main body is used for accommodating the toothed part and a coil of the stator assembly is wound outside the main body; the insulating board is connected to the main body and is formed into a whole with the main body; and a connecting part of the insulating board and the main body can be bent to cover the coil. The invention has the advantages that: the reliable insulating function can be provided for the stator assembly on the premise of not reducing the utilization rate of the groove area so as to maintain the characteristics of the rotating motor, and the complexity of manufacturing the rotating motor can be reduced; moreover, a material preparation project is reduced, and an automatic technology can be introduced to effectively improve the yield.
Description
Technical field
The invention relates to a kind of insulation system and use its electric rotating machine, and particularly about a kind of electric rotating machine that is disposed at the insulation system of stator module and uses it.
Background technology
In general, dispose slot insulators outside the tooth portion of the stator module of motor, with insulation tooth portion and the lead of winding outside slot insulators.In addition, the lead phase mutual interference in two adjacent tooth portions or because of the contact short circuit, insulating paper is disposed between two adjacent tooth portions.
Yet in order to want fixed insulation paper between two adjacent tooth portions, the position of insulating paper needs careful contraposition and adjustment, the project increase that makes the complexity of making improve and get the raw materials ready.In addition, in order to improve the radiating effect of motor, heat-conducting glue is poured in the cell body between adjacent two tooth portions, can conduct to tooth portion by heat-conducting glue with the heat that allows lead produce and shed.Because heat-conducting glue can be expressed in the cell body by modes such as ejaculator or hydraulic presses, therefore, if insulating paper is fixing bad, can cause the insulating paper displacement, and can't positively completely cut off the lead in two adjacent tooth portions.
Though the motor that part is still arranged at present is to adopt the winding number of turns that reduces lead or allow the spacing of the lead in two adjacent tooth portions increase in the mode of twining tooth portion than thin wire, is in contact with one another to avoid lead.Yet the number of turns that lead twines reduces makes the utilization rate of groove area reduce accordingly.Thus, the characteristic of motor (for example being to exert oneself or rotating speed) is affected.In addition, under the same current situation, adopt thinner lead can cause the heat of generation to increase, and then influence the characteristic of motor.
