Description
Technical field:
The utility model relates to a kind of motor end cover component.
Background technology:
Traditional electric machine structure, wiring board is by being installed on the stator module, but this structure wiring board sealed waterproof effect is poor, motor is inapplicable to be installed on the outer machine, for addressing this problem, usually wiring board is installed in sealant pouring and sealing waterproof on the end cap inside, but wiring board is with the end cap encapsulating, difficulty is larger, and the casting glue consumption is more, and is with high costs.
Summary of the invention:
The purpose of this utility model provides a kind of motor end cover component, and this is simple in structure, and cost is low, and sealed waterproof effect is good.
The purpose of this utility model is achieved by following technical proposals.
A kind of motor end cover component comprises end cap, wiring board and box cover, and the box cover is installed on the end cap inside bottom surface, in the groove that wiring board built-in box cover is offered, fills Embedding Material in the groove, Embedding Material cover part or whole wiring board.
The area of box cover described above is less than the area of end cap.
The outer ledge of box cover described above is higher than the outer ledge of end cap.
Some boss are protruded in the bottom surface of box cover described above, are provided with the boss through hole in the middle of the boss, and wiring board is bearing on the boss, and screw is screwed in the end cap by wiring board and boss through hole.
Box cover bottom surface described above offers box cover through hole, and the IPM module that is installed in the wiring board bottom surface is close on the bottom surface of end cap by box cover through hole.
Protrude bearing pedestal in the middle of the end cap described above, at the bearing pedestal outside, wiring board Hall element is installed.
Box cover described above is injection mo(u)lding.
The utility model compared with prior art, have following effect: 1) the utility model is by increasing by a box cover, the box cover is installed on the end cap inside bottom surface, in the groove that wiring board built-in box cover is offered, fill Embedding Material in the groove, Embedding Material cover part or whole wiring board, simple in structure, save the casting glue consumption, reduce cost, and sealed waterproof effect is good; 2) area of box cover dwindles the embedding space less than the area of end cap, saves the casting glue consumption, reduces cost; 3) outer ledge of box cover is higher than the outer ledge of end cap, is used for substituting end cap outer rim protection encapsulating and overflows; 4) some boss are protruded in the bottom surface of box cover, are provided with the boss through hole in the middle of the boss, and wiring board is bearing on the boss, and screw is screwed in the end cap by wiring board and boss through hole, and reasonable in design is installed simple and easy; 5) box cover bottom surface offers box cover through hole, and the IPM module that is installed in the wiring board bottom surface is close on the bottom surface of end cap by box cover through hole, and the IPM module is by the heat radiation of box cover, good heat dissipation effect.
