Abstract: A rotor may include a first rotor core and a second rotor core. The first rotor core includes a first core body and a first teeth protruding from an outer circumferential surface of the first core body. and the second rotor core includes a second core body and a second teeth protruding from an outer circumferential surface of the second core body. Each of the first teeth includes a first extension protruding axially in a first direction, and each of the second teeth includes a second extension protruding axially in a second direction opposite the first direction. The first extension includes a first protrusion provided on a first inner circumferential surface of the first extension, and the second extension includes a second protrusion provided on a second inner circumferential surface of the second extension.

Abstract: The present invention provides an electric pump, the electric pump comprising: a motor unit which includes a shaft, a rotor coupled to the shaft, and a stator disposed outside the rotor; a pump unit which includes a first rotor including a first lobe coupled to the motor unit and having a plurality of gear teeth, and a second rotor disposed outside the first rotor and including a second lobe; and a second cover including a second surface on which the pump unit is disposed, wherein the second surface has a second suction port and a second discharge port disposed thereon, and the second suction port provided on the second surface includes a third protrusion protruding to the inside of the second suction port. The angle formed by a first line connecting the center of the first rotor and the center of the second rotor, and a second line connecting the center of the first rotor and a distal end of the third protrusion is inversely proportional to the number of gear teeth of the first lobe.

Abstract: A rotor includes a first insulator coupled to a first rotor core, and a second insulator coupled to a second rotor core. The first rotor core may include first teeth protruding from a first outer circumferential surface thereof, and the second rotor core may include second teeth protruding from a second outer circumferential surface thereof. The first insulator may include a body configured to surround the first teeth. A first outer guide may be formed at an outside of the body with respect to a radial direction of the first rotor core, and the second insulator may include a body configured to surround the second teeth. A second outer guide may be formed at an outside of the body with respect to a radial direction of the second rotor core. The first teeth and the second teeth may be disposed at different positions with respect to a circumferential direction.
