Abstract
An electric actuator for use with a drive apparatus is disclosed herein. The electric actuator has a rotary design incorporating a position sensor disposed to engage the end of a control shaft. An electric motor drives a reduction gear train to position the control shaft, the reduction gear train having a worm drive that motivates a spur gear reduction. A slip clutch is disposed between the worm drive and spur gear reduction to protect the components of the reduction gear train, and to also place a limit on the torque applied to the control shaft. The housing of the electric actuator features a motor chamber to accommodate the electric motor and is sealed by a cap having an electric connector. The actuator gears may be integrated in a common sump with the drive apparatus.
