Each magnet module includes a base formed of a magnetic material, and two rotor magnets having poles different from each other and provided with a gap therebetween in the rotation direction of the rotary shaft on an outer circumferential surface of the base. The abutting rotor magnets of two magnet modules adjacent in the rotation direction have the same pole and are in close contact with each other.
