Motor is one of critical piece of electric motor car, and the running of motor is that kinetic energy drives vehicle to travel by the electric energy conversion of battery stores.At present, the driving motor of electric vehicle that market occurs is roughly divided into following several: AC induction motor (frequency control), permagnetic synchronous motor, brush direct current motor, switched reluctance machines (SRD) etc., this several motor all needs control system to run, through investigation, all adopt the scheme (as shown in Figure 1) of split type connection at present, be generally common external controller (13) and connect motor Hall line (12) and motor phase line (15) by high-temperature cable (14), control common electric machine (11) and run.
The mode that this split connects adds line loss and system cost, and bring very large inconvenience to installation, failure rate is higher simultaneously.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of control structure of built-in control system motor, controller is arranged on motor internal, makes motor and control device integration, solves the problem of prior art.
Technical scheme: for achieving the above object, the technical solution used in the present invention is: a kind of control structure of built-in control system motor, comprises guard shield, shell, rotor, stator and main shaft; It is characterized in that, comprise electric machine control system; Described electric machine control system is arranged on outside back end cover for motor; Comprise control board, power driving device and Hall adjusting mechanism successively;
Described control board is aluminum annular-shaped substrate, and control board is provided with some electric capacity near motor side; Described control board inserts support column installing hole by metallic support post and fixes, and electric property connects; Control board is provided with some metal solder joints, and connection control chip; Control board extension is provided with some louvres.
Further, described guard shield is provided with air admission hole, guard shield sidewall is provided with venthole.The present invention is because control system is built in electric machine structure, during operation, the winding of motor and semiconductor switch device can produce certain heat, the ventilating opening of the air-flow go side lid that rotor tells running to produce, thermal current was photographed in control system passport, and scavenger fan is got rid of again, the air admission hole of guard shield is due to suction function, suck motor body of wall by waterproof construction cold air, be that winding and control system are operated in stable temperature rise scope, ensured the safety that motor runs.
Described rear end cap edge is evenly provided with bit-avoiding slot.
Beneficial effect: the control structure of a kind of built-in control system motor provided by the invention, fully take into account the factor of power system of electric automobile cost, failure rate and efficiency, mechanical structure and control system carry out integrated relating to, relatively existing split type motor control assembly, motor cost provided by the invention reduces more than 20%, significantly reduces failure rate.Specifically:
1, the motor of existing external control system, needs to provide cable to connect, eliminates cable assembly after the present invention is integrated, not only reduces cable assembly originally, decreases the loss of cable power supply simultaneously;
2, existing split type connection needs two housings, i.e. electric machine casing and controller housing, and the present invention integrated after eliminate the cost of controller housing;
3, saved installing space and mounting material, decreased line loss, improved system effectiveness, structure is attractive in appearance through gathering simultaneously, simplifies mounting process, and has saved cost of labor.
