A motor is used in a compressor. The motor includes a stator including a stator core having a yoke part that extends in a circumferential direction about an axis and a plurality of teeth that extend from the yoke part toward the axis and are arranged in the circumferential direction, and a winding wound around the plurality of teeth of the stator core in wave winding, and a rotor whose number of poles is P and which is disposed on an inner side of the stator in a radial direction about the axis. When a number of the plurality of teeth is represented by S, S/P≥6 is satisfied. The yoke part has a refrigerant passage through which refrigerant passes in a direction of the axis.
