ABSTRACT:
A system and method for precisely controlling lubricant supply flow to one or more rotating machines in an aircraft includes a motor, a pump, and a motor control unit. The motor is coupled to receive motor speed commands and, in response to the commands, rotates at the commanded motor speed and supplies a drive force to the pump. The pump, upon receipt of the drive force, draws lubricant from a lubricant source and supplies it to a rotating machine. The motor control unit determines a scheduled lubricant supply pressure based at least in part on lubricant temperature, rotating machine rotational speed, and one or more aircraft operating conditions, and to supplies the motor speed commands to the motor that cause the pump to supply lubricant at the scheduled lubricant supply pressure.
