Valve is controlled valve opening and closing, is only opened and closed two states, it is impossible to accomplish precise control.And current automotive industry is to energy profit
With rate, environmental requirement more and more higher, it is necessary to carry out precise control to valve to meet demand.The brushed DC used at present is electronic
Trough type often has larger operating cogging torque, and sensitivity is low, poor to valve location Accuracy control, and volume is larger,
High cost.
The content of the invention
To solve the above problems, the utility model provides a kind of automobile exhaust gas recirculating system driving direct current generator, greatly
It is big to reduce operating cogging torque, sensitivity is improved, the accuracy of automobile exhaust gas recirculating system valve location control is lifted, and
Small volume, low cost.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of automobile exhaust gas recirculating system driving direct current generator, including casing, be matched with casing annular stator,
Annular rotor, the coaxial rotating shaft being fixed in rotor in stator, are provided between stator and rotor and are fixed on rotor
Ring-type magnetizes magnet steel, four positioning convex being engaged with casing inner ring is evenly distributed along the outer shroud of stator, on stator
Arcuate edge is provided between two adjacent positioning convex, heat dissipation channel is provided between arcuate edge and casing, in stator
Inner ring be evenly distributed between 48 helical teeth, adjacent helical teeth and form skewed slot, the width of rebate of skewed slot is 1mm, helical teeth
Provided with 5 ° of angles between center line and stator radial direction.
The magnet steel that magnetizes uses radial magnetizing.
The utility model is adapted for use with the engine working area of automobile exhaust gas recirculating system, the design of heat dissipation channel
Maximum operation temperature can be met and reach 160 °C, the higher and higher trend of present engine temperature rise is met.It can be operated in most simultaneously
Under big 40g acceleration condition of work.Efficiency improves about more than 10% than traditional brush direct current motor efficiency；Electrical machinery life is
More than 2 times of traditional brush direct current motor life-span, while groove profile and the design magnetized, greatly reduce operating cogging torque, than
The operating cogging torque reduction by more than 20% of traditional brush direct current motor product, improves sensitivity, greatly promotes automobile exhaust gas again
The accuracy of circulatory system valve location control；Reduce instantaneous large-current loss of the motor in start-up course, the longevity of battery
Life can extend more than 1.3 times than the brushed DC motor using same power, and motor volume reduces 20%, cost reduction
20%。
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.

Arcuate edge 2-2 is provided between raised 2-1, heat dissipation channel 5 is provided between arcuate edge 2-2 and casing 1, in stator 2 and rotor 3
Between magnetized magnet steel 6 provided with the ring-type for being fixed on rotor 3, the magnet steel 6 that magnetizes uses radial magnetizing.
Formation skewed slot 2-4 between 48 helical teeth 2-3, adjacent helical teeth 2-3 is evenly distributed in the inner ring of stator 2, tiltedly
Groove 2-4 width of rebate H is 1mm, and 5 ° of angle α is provided between helical teeth 2-3 center line and the radial direction of stator 2.
The utility model is installed on before the cylinder of automobile exhaust gas recirculating system between outlet and automotive air intake pipe,
The rotating shaft 4 of motor is connected with the worm screw of automobile exhaust gas recirculating system, worm drive booster worm gear, will be gone out before cylinder
The portion discharge of mouth, finally injects automotive air intake pipe, maximum operation temperature can reach 160 °C, while can be operated in
Under maximum 40g acceleration condition of work.Efficiency improves about more than 10%；Electrical machinery life improves more than 2 times, groove profile and magnetizes
Design, greatly reduce operating cogging torque, than traditional brush direct current motor product operating cogging torque reduction by 20% with
On, sensitivity is improved, the accuracy of automobile exhaust gas recirculating system valve location control is greatly promoted；Reduction motor was starting
