Abstract
The utility model relates to technical field of motors, especially a kind of end cap of hybrid exciting synchronous motor.A kind of end cap of hybrid exciting synchronous motor, comprise end cap body, described end cap body is provided with through hole, the bearing holder (housing, cover) of stainless steel is provided with in described through hole, between bearing holder (housing, cover) and end cap body, be lined with electro-insulating rubber, described bearing holder (housing, cover) comprises the bearing end cover be arranged on outside end cap body and the internal bearing cover be arranged on inside end cap body.This structure avoids the axial magnetic flux in stator back yoke to be closed by end cap, maintains the effect regulating the average magnetic of air gap close, avoids causing shaft current.
Description
Technical field
The utility model relates to technical field of motors, especially a kind of end cap of hybrid exciting synchronous motor.
Background technology
Hybrid exciting synchronous motor is a kind of novel electric machine structure form proposed the earliest by Russian scholar the eighties in last century.Different from traditional electric excitation synchronous motor and permanent magnetic synchronous motor structure.In hybrid exciting synchronous motor, existing permanent magnet has excitation winding again, two magnetic potential sources exist simultaneously, it is integrated with that electric excitation synchronous motor adjustable magnetic is convenient and the advantage such as adjustable magnetic capacity is little and permanent magnet synchronous electric engine efficiency is high, torque/mass ratio is large, overcome again the defect of permagnetic synchronous motor flux control difficulty simultaneously, have larger application value.Axial magnetic flux in existing hybrid exciting synchronous motor stator back yoke is closed by end cap, can lose the effect regulating the average magnetic of air gap close, cause shaft current simultaneously.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of end cap of hybrid exciting synchronous motor.
The utility model solves the technical scheme that its technical problem adopts: a kind of end cap of hybrid exciting synchronous motor, comprise end cap body, described end cap body is provided with through hole, the bearing holder (housing, cover) of stainless steel is provided with in described through hole, between bearing holder (housing, cover) and end cap body, be lined with electro-insulating rubber, described bearing holder (housing, cover) comprises the bearing end cover be arranged on outside end cap body and the internal bearing cover be arranged on inside end cap body.
In end cap through hole, be provided with the bearing holder (housing, cover) of stainless steel, effectively can prevent the axial leakage field of motor, be also convenient to installation and the replacing of bearing simultaneously; Between bearing holder (housing, cover) and end cap body, be lined with electro-insulating rubber, effectively can prevent the generation of shaft current.
Further, the bolt appearance of described end cap body and connecting axle bearing sleeve all scribbles one deck insulating varnish.Such design, can prevent the generation of shaft current further.
The beneficial effects of the utility model are: this structure avoids the axial magnetic flux in stator back yoke to be closed by end cap, maintain the effect regulating the average magnetic of air gap close, avoid causing shaft current.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. end cap body, 2. bearing holder (housing, cover), 3. electro-insulating rubber, 4. internal bearing cover, 5. bearing end cover.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of end cap of hybrid exciting synchronous motor, comprise end cap body 1, end cap body 1 is provided with through hole, the bearing holder (housing, cover) 3 of stainless steel is provided with in through hole, between bearing holder (housing, cover) 3 and end cap body 1, be lined with electro-insulating rubber 2, bearing holder (housing, cover) 3 comprises the bearing end cover 5 be arranged on outside end cap body 1 and the internal bearing cover 4 be arranged on inside end cap body 1.
Further, the bolt appearance of end cap body 1 and connecting axle bearing sleeve 3 all scribbles one deck insulating varnish.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
