Abstract
An electric pump of the present invention includes a stator assembly having an annular transverse section, and a rotor assembly rotatably supported in a center hole of the stator assembly and selectively rotating in a desired direction in cooperation with the stator assembly. At least a portion of an outer peripheral surface of the rotor assembly is formed into a shape of a blade for an axial-flow pump.
