Motor Control Electronics

Parker Aerospace designs and manufactures a variety of reliable and efficient motor control electronics (MCE) for flight control actuation. 

MCEs provide closed-loop velocity control of the motors used in aerospace applications such as aircraft pitch trim and flap systems. 

The MCE utilizes existing computing and communication resources to provide local motor control for control surface actuation. 

High-integrity data buses and the selection of higher-voltage operation significantly reduces the amount of aircraft wiring. 

Parker motor control electronics can utilize the most demanding input power requirements such as DO160G Section 16 CAT A (WF) allowing operation down to as low as 320Hz for some applications supported by RAM air turbine (RAT) power.

Parker's pedigree in motor control electronics is well established, supplying all of the pitch trim actuation control on Bombardier's C Series, the Embraer Legacy 450/500 pitch trim and flap system, as well as the COMAC C919 pitch trim. 

The Parker MCE designs have met or exceeded all applicable certification requirements levied by the world’s certification agencies. 

Parker motor control electronics or motor controllers for electro-mechanical actuation (EMA) as well as electric backup hydraulic actuation (EBHA) and electrohydrostatic actuation (EHA) have all been developed for a variety of commercial and military aerospace applications, including safety-critical primary flight-control surfaces. 

The designs are housed in enclosures for installation outside the pressure vessel in relatively harsh environments.
