Summary:A motor includes a stator that includes a stator core and coils. The stator core is formed of a magnetic material and has a plurality of teeth arranged at intervals in a circumferential direction. The coils are formed of electrically-conductive windings wound around the teeth. Moreover, the motor also includes a rotor having a plurality of magnets arranged in radial opposition to the stator core and at intervals in the circumferential direction. The rotor is configured to rotate upon supply of electric current to the coils. Furthermore, the motor also includes a plurality of pseudo-teeth formed of a magnetic material and each located in a circumferentially intermediate area between a circumferentially-adjacent pair of the teeth. The pseudo-teeth are arranged so as to be concentrated in a part of the stator core in the circumferential direction.
