Abstract:
An external gear pump includes a pump housing in which a pump chamber is formed, a primary gear having a plurality of external teeth housed in the pump chamber, a secondary gear having a plurality of external teeth that mesh with the plurality of external teeth of the primary gear in the pump chamber, a first electric motor configured to generate a torque for rotationally driving the primary gear, a second electric motor configured to generate a torque for rotationally driving the secondary gear, and a control unit configured to control the first and second electric motors. The control unit controls the first and second electric motors so that the torque generated by the first electric motor is greater than the torque generated by the second electric motor.
