Abstract:
1. An electric actuator in communication with a drive controller for adjusting the rotational position of a control shaft on a drive apparatus, the electric actuator comprising: an actuator housing having a motor chamber and a gear chamber; an electric motor disposed in the motor chamber and comprising a plurality of electric contacts and a motor output shaft passing through to the gear chamber; a cap mounted to the actuator housing to seal the electric motor in the motor chamber, and an electric connector passing through the cap to communicate with the plurality of electric contacts; a worm drive disposed in the gear chamber and driven by the motor output shaft; a spur gear reduction disposed in the gear chamber and driven by the worm drive, wherein the spur gear reduction is engaged to the control shaft to adjust its rotational position; a slip clutch disposed in the gear chamber between the worm drive and the spur gear reduction; and an angular position sensor disposed on the actuator housing, wherein the angular position sensor is capable of engaging a first end of the control shaft and communicating the rotational position of the control shaft to the drive controller.
