The present invention provides A motor comprising: a shaft; a rotor including a hole in which the shaft is disposed; and a stator outside the rotor, wherein the rotor comprises a rotor core and a magnet, wherein the rotor core comprises: a main body; a pocket which is formed in the main body and in which the magnet is disposed; first barriers extending from both sides of the pocket; and second barriers formed between an inner circumferential surface of the main body and an outer circumferential surface of the main body, wherein a center (C) of the second barrier has a certain arrangement angle (&#x3b8;) in a circumferential direction from a first line (L) passing through a center (CC) of the main body and a center of a width (W) of the magnet.

Electric pump and motor

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.
