Technical scheme：For achieving the above object, the technical solution used in the present invention is：A kind of built-in control system motor support structure, including shield, shell, rotor, stator and main shaft；Characterized in that, including electric machine control system；
Shield, control system, rear end cap, shell are followed successively by by motor side to opposite side；Inside the shell includes rotor, stator 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 on the annular brace platform fairlead is provided with；
The annular brace platform is insulant, and surface is evenly distributed with passage, and the passage connects motor body inner chamber and protective cover.The annular brace platform outside is provided with fixed groove, and the groove is adapted with the projection of shield inwall.
Further, air inlet is provided with the shield, shroud wall is provided with venthole.The present invention is because control system is built in electric machine structure, during operation, the winding and semiconductor switch device of motor can produce certain heat, rotor tells the vent of the air-flow go side lid of operating generation, and thermal current was photographed in control system passport, and scavenger fan is excluded, the air inlet of shield is due to suction function, motor body of wall is sucked by waterproof construction cold air, is that winding and control system are operated in stable temperature rise scope, ensured the safety of motor operation.
The rear end cap edge is evenly arranged with bit-avoiding slot.
Beneficial effect：A kind of built-in control system motor support structure that the present invention is provided; fully take into account the factor of power system of electric automobile cost, fault rate and efficiency; by the annular supporting structure, can be run in a metastable environment with Protection control system, and play a part of fixed support.
