386 - 3439 Excavator Throttle Motor E320D2 Accelerator Motor Excavator Part

Specifiion

Description

A throttle controller for an internal combustion engine employs a stepper motor to move the throttle valve and provides a controller to permit the use of the stepper motor. The stepper motor requires no return spring or position sensor and hence offer weight and cost advantages. The throttle position is deduced by means of an up-down counter tracking movement of the stepper motor during throttle control. The controller includes an integration means to accommodate the unknown starting throttle position. A fuel cutoff solenoid is activated in the event of over-speed or power loss. An engine speed signal for the controller is produced by a variable reluctance sensor providing a signal to a slope detector circuit to eliminate the influence of external magnetic fields.

Characteristic

1.the internal high-speed gear is powder metallurgy material, to ensure strength and wear resistance, and has self-lubriing grease performance, quiet performance, low-speed gear is special engineering plastics, ensuring reliable and durable
2.the use of high-reliability and high-quality seals, effectively improve the waterproof and dustproof performance of the motor, the protection ability reaches p54
3.using the original imported positioner, durable and accurate;
4.Eliminating the mechanical element of a throttle cable and substituting it with fast responding electronics, reduces the number of moving parts (and associated wear) and therefore requires minimum adjustment and maintenance.
5.Greater accuracy of data improves the driveability of the vehicle, which in turn provides better response and economy.
