Stator module is nested in outside rotor assembly, and cavity is offered in the middle of end cap, and rotor assembly and stator module are arranged in cavity
Face, is provided with insulating end plate between coil windings and end cap end cap, conventional insulating end plate is put into end cap, insulating end for convenience
The external diameter of plate can be less than end cap internal diameter, because the external diameter of insulating end plate can be less than end cap internal diameter, so insulating end plate is in end cap
It is to loosen, when overturning end cap assembling motor, insulating end plate is very easy to drop or crooked loses insulation function.
The content of the invention：
The purpose of this utility model is to provide a kind of insulation system, and it is pine in end cap to solve insulating end plate in the prior art
Dynamic, when overturning end cap assembling motor, insulating end plate is very easy to drop or the crooked technical problem for losing insulation function.
The purpose of this utility model is achieved by following technical proposals.
A kind of motor insulation structure, including end cap, stator module, rotor assembly and rotating shaft, its end cap are provided with bearing chamber,
Bearing is installed, rotating shaft is arranged on rotor assembly in bearing chamber, stator module include stator core, overhang insulation and coil around
Group, overhang insulation surface of the coil windings on stator core, stator module is nested in outside rotor assembly, two end caps
Middle formation cavity volume is installed together, rotor assembly and stator module are arranged on inside cavity volume, the top of coil windings and end cap
Inner top surface between leave insulating end plate be installed in gap, gap, the insulating end plate edge protrudes above several boss, convex
The external diameter of platform is bigger than the internal diameter of end cap.
Insulating end plate described above is that through hole is offered in the middle of annular ring, annular ring, and insulating end plate is set with by through hole
In bearing chamber periphery.
Boss described above is to be radially arranged.
Boss described above is uniformly correspondingly arranged.
The utility model compared with prior art, has the effect that：
1) the utility model includes end cap, stator module, rotor assembly and rotating shaft, and its end cap is provided with bearing chamber, bearing
Bearing is installed, rotating shaft is arranged on rotor assembly, and stator module includes stator core, overhang insulation and coil windings in room,
Overhang insulation surface of the coil windings on stator core, stator module is nested in outside rotor assembly, two end cap peaces
Be fitted together it is middle form cavity volume, rotor assembly and stator module are arranged on inside cavity volume, the tops of coil windings and end cap
Left between inner top surface and insulating end plate is installed in gap, gap, the insulating end plate edge protrudes above several boss, boss
External diameter it is bigger than the internal diameter of end cap, so boss is tightly pressed against the inwall of end cap, so that insulating end plate is fixedly secured, be difficult
Loosen, insulating end plate is also prevented effectively from when end cap is assembled and is released causes to drop or the phenomenon such as crooked, simple in construction.

Embodiment：
The utility model is described in further detail below by specific embodiment and with reference to accompanying drawing.
Embodiment one：As shown in Figures 1 to 6, the present embodiment is a kind of motor insulation structure, including end cap 1, stator module
2nd, rotor assembly 3 and rotating shaft 4, its end cap 1 are provided with bearing chamber 13, bearing chamber 13 and are provided with bearing 14, and rotating shaft 4 is supported on axle
Hold on 14, rotating shaft 4 is arranged on rotor assembly 3, stator module 2 includes stator core 21, overhang insulation 22 and coil windings 23,
Overhang insulation 22 surface of the coil windings 23 on stator core 21, stator module 2 is nested in the outside of rotor assembly 3, two
Individual end cap 1 is installed together middle formation cavity volume 11, and rotor assembly 3 and stator module 2 are arranged on the inside of cavity volume 11, coil windings
Left between 23 top and the inner top surface of end cap 1 and insulating end plate 5 is installed in gap 12, gap 12, the side of insulating end plate 5
Edge protrudes above several boss 51, and the external diameter of boss 51 is bigger than the internal diameter of end cap 1, so boss 51 is tightly pressed against end cap 1
Inwall, so that insulating end plate 5 is fixedly secured, is difficult to loosen, the pine of insulating end plate 5 is also prevented effectively from when end cap 1 is assembled
It is de- to cause to drop or the phenomenon such as crooked, it is simple in construction.
