Problem.
Technical scheme：For achieving the above object, the technical solution used in the present invention is：A kind of built-in control system motor
Rear end cover structure, including shield, shell, rotor, stator and main shaft；Characterized in that, including motor control system
System；
Shield, control system, rear end cap, shell are followed successively by by motor side to opposite side；Inside the shell includes rotor, determines
Son and main shaft；Outermost is drive end bearing bracket；
The motor rear end outer side of lid includes the annular brace platform of a projection, and rear end cap is provided with air inlet, shroud wall
It is provided with venthole；
Include rear end cap lead on the rear end cap, the rear end cap lead, connection motor and control system；
Metal-oxide-semiconductor groove and phase line connecting pole are evenly arranged with the rear end cap；The phase line connecting pole is conductor material.
The rear end cap edge is evenly arranged with bit-avoiding slot.
Beneficial effect：The rear end cover structure of a kind of built-in control system motor that the present invention is provided, fully takes into account electronic
The factor of car dynamical system cost, fault rate and efficiency, carry out in frame for movement with control system it is integrated be related to, phase
For existing split type motor control assembly, the motor cost that the present invention is provided reduces more than 20%, significantly subtracts
Low fault rate.Specifically：
1st, the motor of existing external control system, it is desirable to provide cable connection, eliminates after the present invention is integrated
Cable assembly, not only reduces cable assembly sheet, while decreasing the loss of cable power supply；
2nd, existing split type connection needs two housings, i.e. electric machine casing and controller housing, and the present invention is integrated
The cost of controller housing is eliminated after integrated；
3rd, installing space and mounting material have been saved, line loss has been reduced, system effectiveness has been improved, while structure Jing
Gather attractive in appearance, simplify mounting process, and saved cost of labor.
