Abstract:
To provide a motor that has a stator subjected to a relatively simple processing and achieves sufficient reluctance torque, and to provide a motor unit having the motor.
A motor includes: a stator (50) that has an annular back yoke (52), and teeth (53) which project radially inward from the back yoke (52); and a rotor (70) that is arranged on an inner side of the stator (50) and has a plurality of permanent magnets (72) embedded thereinside. Each of the teeth (53) has a gap (80) formed therein so as to reduce inductance in a direction of a d-axis. The gaps (80) extend in directions in which the respective teeth (53) project.
