Original Abstract Submitted

an electric motor has a rotor with a plurality of magnets arranged on a surface of the rotor. when viewed along an axial direction of the rotor, the plurality of magnets may have following features: a direction of a magnetic pole of each of the plurality of magnets is rotated by 45 degrees sequentially from one to next along a circumferential direction of the rotor; and a width of each of the magnets of which the magnet pole direction is inclined by 45 degrees relative to a radial direction of the rotor is wider than a width of each of the magnets of which the magnet pole direction coincides with the circumferential direction or the radial direction.
