A motor includes a stator having windings and a rotor. The rotor includes a rotor core and a first magnet magnetic pole, a second magnet magnetic pole, and a protrusion provided next to each other in the circumferential direction. The second magnet magnetic pole has an opposite polarity to the first magnet magnetic pole. The protrusion projects in the radial direction in the rotor core. The windings include a first winding and a second winding. The first winding and the second winding are excited at the same timing, and are serially connected. The protrusion faces the second winding at the rotor rotation position at which the first magnet magnetic pole or the second magnet magnetic pole faces the first winding.
