According to the compactly-designed motor pump, the motor shell and the gear pump shell are tightly combined; the gear pump is placed in the motor and arranged in the radial direction, the high radius of the motor is facilitated, the torque capacity of the motor is improved, and the pump with higher power density is allowed to be placed in the electromagnet; a special oil inlet and a special oil outlet are formed in the right side of the shell; the motor rotor and the gear pump share one shaft; radial fans are installed at the two ends of the rotor, and the overall heat dissipation capacity of the motor pump is improved. According to the invention, the permanent magnet synchronous motor and the gear pump are tightly combined, so that the objectives of optimization of compactness, power density ratio, energy efficiency and stability are achieved.
