PROBLEM TO BE SOLVED: To provide a motor that makes it possible to increase torque without newly ensuring a magnet installation space and can be reduced in size. SOLUTION: The motor includes at least either of a rotor 11 and a stator 14. The rotor has a magnetic flux generating member that generates magnet magnetic flux equivalent to multiple different numbers of magnetic poles on its surface in a combined manner. The stator is supplied with a current so that multiple magnetic fields corresponding to the multiple numbers of magnetic poles can be combined and rotated. Magnetized magnets 12 are disposed at a portion where magnetic flux is reduced by the combination of magnet magnetic flux so that magnetic flux is concentrated on a portion where magnetic flux is increased by the combination of magnet magnetic flux. The magnetic flux of magnets 12 disposed at least part of the portion where magnetic flux is reduced by the combination of magnet magnetic flux is concentrated on the portion where magnetic flux is increased by the combination of magnet magnetic flux in one or more directions of magnetization.
