Abstract

An object of the present invention is to provide a motor (100) advantageous for cost reduction while suppressing performance degradation. A motor (100) includes a stator (2) including an iron core (21) having a plurality of teeth (22) and a plurality of slots (24) extending in a radial direction, and a winding wire (25) wound around each of the slots (24), and a rotor (3) including a magnet (32) including magnetic poles (33) facing the plurality of teeth (22) in the radial direction. The iron core (21) is integrally formed in a circumferential direction, and the magnet (32) is formed of a material having a residual magnetic flux density of 1.4 T or more, and an iron core utilization rate of the iron core (21) is less than 60%.
