Simultaneously, the stator core of current domestic use in washing machine single-phase asynchronous motor is that four outer surfaces are all directly in atmosphere exposed, on the one hand, its rust-proof effect is poor, is in the easy corrosion of wet environment for a long time, on the other hand, its radiating effect is also poor, the heat generated after motor long time running not easily passes away, and the temperature of motor winding can be caused too high, and temperature rise easily exceedes designing requirement.
Utility model content
The purpose of this utility model is the end-cap assembly providing a kind of use in washing machine single-phase asynchronous motor, improves electric machine iron core surface antirust, anti-corrosive effect and electric machine iron core heat conduction and heat radiation ability, and meanwhile, achieving can the mechanical type production of non-destructive dismountingization.
For achieving the above object, the utility model have employed following technical scheme: comprise the front end housing body and rear end cap body that are fixed on stator core both sides, described rear end cap body has rear portion mounting groove for installing stator core side winding coil and the otic placode for fixed stator iron core and front end housing body, described front end housing body has the anterior mounting groove for installing stator core opposite side winding coil, the edge of opening place of described anterior mounting groove is provided with the occlusion part for wrapping up stator core, the relative both sides of described occlusion part are respectively equipped with the transverse slat extended radially outwardly along its bottom margin, described transverse slat contacts setting with otic placode is opposing parallel, described transverse slat is provided with multiple unthreaded hole, described otic placode is provided with multiple screwed hole corresponding with unthreaded hole.
Further, the edge of described anterior mounting groove has the connecting portion extended radially outwardly, and described occlusion part is the shield along connecting portion edge-perpendicular to downward-extension, and the outer shape of the inner chamber that described shield and connecting portion are formed and described stator core matches.
Further, described front end housing body is provided with multiple positioning boss with relative respectively on rear end cap body, and the both sides of described stator core are provided with the location hole that to match with described boss.
Further, described boss is located on otic placode and connecting portion respectively.
As shown from the above technical solution, the utility model improves the antirust, anti-corrosive ability on motor stator core surface effectively, and the ability of heat conduction and heat radiation, reduces the temperature rise of motor; Meanwhile, replace bolt assembly or rivet assembling with trip bolt assembling, both can realize plant machineryization and produce replacement manual production, and improve motor gas-gap uniformity, reduce electromagnetic noise, the non-destructive dismounting of motor can be realized again.
