Description:
This electrical actuator was designed by VDO for the purpose of operating a diesel engine fuel-injection pump lever in conjunction with a VDO electronic con- troller. A pulse-width modulated (PWM) signal is used to control the permanent magnet DC motor.
Construction:
Watertight cast aluminum housing with PTFE membrane for pressure equaliza- tion. Three-stage transmission transfers force from the DC motor to the output shaft via an electromagnetic clutch. A conductive plastic potentiometer provides feedback. Connecting cable with connector.
