Superior Motion Control, designed and manufactured this custom electromechanical linear servo actuator to be used to control a thermostatic control valve to heat and cool the Jamming Pod on the EA-18 Growler.

The custom mechanical design incorporates a brushless DC motor driving a 3 pass spur gear train and dual start ACME screw.

The self-contained custom electrical serial interface, servo control, motor drive electronics, firmware, and software were developed and tested by Superior.

Software was designed in accordance with DO-178. Valve positioning is accomplished by using the motor hall effect sensors as an incremental position encoder.

Software controls the initialization of the valve position upon power up.
