Auxiliary Unit Fuel Pump

In the control of gas turbine engines used in aircraft auxiliary power units (APU) that must operate at tens-of-thousands of rpm, fuel pump frequency response and reliability are two key design parameters.

Allied Motion engineers, working closely with the turbine manufacturer of this gerotor-type fuel pump, optimized the parameters of the pump motor, an Allied Motion Megaflux frameless brushless torque motor, resulting in an economical solution that exceeded performance and reliability goals.
