Air inlet is provided with the shield, shroud wall is provided with venthole；Shroud edge is evenly arranged with bit-avoiding slot, and the bit-avoiding slot internal diameter is adapted with the locating dowel external diameter on shell；
Shield inwall scribbles insulating protective layer, and shield inwall is evenly arranged with strip projected parts.
The shell is insulant.
Vent is provided with the shell.
Beneficial effect：The shield structure of a kind of built-in control system motor that the present invention is provided, fully take into account the factor of power system of electric automobile cost, fault rate and efficiency, carry out integrated being related in frame for movement with control system, for relatively existing split type motor control assembly, the motor cost that the present invention is provided reduces more than 20%, significantly reduces fault rate.Specifically：
1st, the motor of existing external control system, it is desirable to provide cable connection, after the present invention is integrated cable assembly is eliminated, and cable assembly sheet is not only reduced, 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 cost of controller housing is eliminated after the present invention is integrated；
3rd, installing space and mounting material have been saved, line loss has been reduced, system effectiveness has been improved, while structure Jing is gathered attractive in appearance, has simplified mounting process, and saved cost of labor.
