Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a motor-driven oil pump device controllable so as to make an actual value match a command value. SOLUTION: The motor-driven oil pump device 1 comprises a fluid force feeding pump 5 for supplying fluid pressure to a fluid circuit 2, a brushless motor 4 for providing a rotating drive force to the fluid force feeding pump 5, and a brushless motor control device 3 for rotation driving the brushless motor 4 according to a control signal from an ECU 20. The brushless motor control device 3 comprises a torque correcting means 308 for providing a correction amount according to the mechanical loss amount generated from the brushless motor 4, a fluid force feeding pump 5, the fluid circuit 2, and the like to a drive signal of the brushless motor 4.
