This electric motor includes: a brushless motor (); and a control device () that is coupled integrally to an end of a motor case () in an axial direction. The control device () includes: a bus bar unit main body () that has a base unit () with a plurality of bus bars wired thereinside and has a connector unit () provided integrally on the base unit () and led out to an outside of a housing (); a motor drive unit () that drives the brushless motor (); and a motor control unit () that controls the motor drive unit (). The motor drive unit () is attached to a first main surface () of the base unit () while the motor control unit () is attached to a second main surface () of the base unit ().

Electric motor and electric pump

A fuel pump wherein the inner cylinder 37 for forming the fuel duct 38, in the outer cylinder 14, is provided between the stator 34 and the rotor 32 of the brushless motor 12, one end portion of the inner cylinder 37 is blockaded by the holder plate 41. The contacting pipe 44 for connecting from the fuel duct 38 to the delivery duct 21 is protrudely provided at the holder plate 41, and the control circuit unit 13 of the brushless motor 12 is held thereon. A resin sealed portion 52 is formed between the outer cylinder 14 and the inner cylinder 37, and the circumference of the control circuit unit 13 in the inner cylinder 37 by a potting method. The fuel 54 is lead from the introductory duct 16 to the fuel duct 38 of the inner cylinder 37, and is delivered from the delivery duct 21 through the insides of the fuel duct 38 and the contacting pipe 44. Since the fuel 54 does not contact on the resin sealed portion 52 and the control circuit unit 13, it is possible to prevent electric corrosion, conduction and a short of the resin sealed portion 52 and the control circuit unit 13 by the fuel 54.
