Correspondingly, the power circuit board is coaxially parallel with control circuit board, and is fixed by connection terminal.
Preferably, the controller is fixedly connected by bolt with brshless DC motor.
Preferably, radiating insulating piece is filled between the cap and power circuit board.
Preferably, the radiating insulating piece is silica gel cloth.
Compared with the prior art, the invention has the following beneficial effects:
The present invention is based on the brushless motor controller of EPS system, including controller and brshless DC motor, the controllers
Inside it is provided with cap, shell and circuit board；Circuit board potting is mounted in the shell of controller by the present invention, can both be dropped in this way
Low subsequent circuit board element production installation processing and fabricating workload, improves production efficiency, and can efficiently use cap and shell
Redundant space in body reduces the height space of whole circuit board and reduces the outer dimension of whole circuit board, finally makes entire
The structure of controller is more compact, and the subsequent disposable qualification rate of production and processing is higher, and production quality is effectively controlled.This hair
It is bright by controller and the integrated design of brshless DC motor, improving product safety and reliability and make to a greater extent
With effect, product quality is improved, traffic safety accident risks is reduced and occurs, whole device response is fast rapidly, light structure, is convenient for
Maintenance, is greatly saved the assembly space of automobile steering system, and power density is big, gives full play to the excellent of brshless DC motor
Gesture.
