Abstract
(EN)
An electric oil pump 1 according to the present invention is provided with: an oil pump unit 2 which comprises a pump rotor 8 and a pump housing 10 that contains the pump rotor 8; a motor unit 3 which comprises a motor rotor 16, a motor stator 17, and a motor housing 18 that contains the motor rotor 16 and the motor stator 17; a control unit 4 which controls the driving of the motor unit 3; and first and second bearings 27, 28 that support rotary shafts 5, 6, which protrude from the motor rotor 16 in the axial direction, at two points in the axial direction. The pump housing 10 and the motor housing 18 are integrally formed; and both of the first and second bearings 27, 28 are needle roller bearings.
