A motor for an electric vehicle includes a frame, a stator disposed in the frame, a rotor disposed to be rotatable with respect to the stator; and an engaging portion that restricts the stator from moving with respect to the frame in a circumferential direction, the engaging portion including at least one rib protruding from one of the surfaces of the frame and the stator, and at least one rib accommodation portion formed at other of the surfaces of the frame and the stator, wherein the at least one rib and the at least one accommodation portion are engaged to allow heat to be transferred therebetween. Under this configuration, a cooling performance may be improved and durability may be enhanced.
