Abstract:

To reduce the effect of electric noise generated from a coil without increasing the number of components in an electric pump having a can for preventing flow-in of the fluid in a pump unit into a stator.

An electric pump includes a rotor 12 journaled by a housing 2 at a rotary shaft 15, a stator 13 positioned on an outer side in the radial direction of the rotor 12 and fixed to the housing 2, a pump unit 20 for sucking and discharging the fluid in response to a rotation of the rotor 12, and a can 14 positioned between the rotor 12 and the stator 13 for preventing the fluid in the pump unit 20 from flowing into the stator 13.
