In the case of slow-revving, now IMRC is closed, it is possible to the air entering into electromotor is less, and the oil consumption caused is also
Relatively low.Electromotor be in high-revolving in the case of, now IMRC can Open valve, it is possible to the air entering into electromotor increases
Add, thus increase the power output of electromotor.So, we just avoid idling mode by the control of inlet manifold air inflow
Under unnecessary fuel oil waste, thus reach the purpose of energy-saving and emission-reduction.
The angular position sensor part of current inlet manifold runner controller product mostly is purely mechanic contact slide variable resistance
Formula structure, structure is complex, and parts are more, and precision and performance requirement to parts are higher, and in use unit
Part can produce frictional dissipation, reduces stability and the service life of product, thus affects the output accuracy of signal.And some non-connect
The sensing controler of touch in use rotating function to motor can not reach effectively to control and precision transmission
Accurately, when being easily caused signal output, there is error in product response time from opening to closure state, it is impossible to exactly
The information of automobile and the duty of product are effectively monitored.It addition, existing inlet manifold runner controller is no matter
It is contact type structure or protection time motor that contactless structure is used the most does not dallies, is controlling inlet manifold stream
When road valve reaches opening and closure state, when can not rotating such as driven by motor load, motor temperature can be easily caused
Quickly raise and the burden of drive disk assembly increases, it may appear that the phenomenon that motor is stuck and drive disk assembly is stuck, affect making of motor
With the life-span, the fracture of drive disk assembly and burning of motor time serious, can be caused.

Response time from opening to closure state, thus realize the information of automobile MCU is fed back and product working status
Monitoring.In terms of the driving of system, motor is driven by the control circuit using H bridge to be core, then by motor driven gear
Rotating thus moment of torsion, rotational angle and corresponding changes of magnetic field required for output of group, control circuit has control motor
The function of rotating, thus realize rotating clockwise and rotating counterclockwise of output shaft, then control to make by output shaft
The unlatching of inlet manifold runner valve and Guan Bi；Additionally on motor output shaft, it is configured with magnetic coupler can motor be protected
Protect, also gear train is made important protection；When gear train is restricted from rotating, motor also can as usual rotate, prevent electricity
The appearance that machine card pauses, is effectively protected motor, it is possible to the burden alleviating gear train prevents broken teeth phenomenon from occurring, and can be electricity
