An electric actuator for use with a variable drive apparatus is disclosed herein. The electric actuator has a rotary design incorporating a magnetic field sensor chip disposed on a circuit board to sense the rotational orientation of the magnetic field of a cylindrical diametric magnet positioned on the end of a control shaft of a hydrostatic drive unit. The circuit board includes a microprocessor, electric motor power control and CAN Bus communication capability. The gear housing of the electric actuator features an integral end cap to accommodate mounting of the electric motor to enable a compact design. A vibration damping apparatus may be utilized to improve integrity of signals generated by the magnetic field sensor chip.
