Abstract:
A stepper motor includes: a rotor (2) including a rotor core (21,22) and a permanent magnet (23), the rotor core (21,22) including a plurality of teeth (21A,22A); and a stator (3) arranged around the rotor (2) while being spaced apart from the rotor (2) and including a plurality of magnetic pole teeth (31), the magnetic pole teeth (31) including a plurality of sub-teeth (33) and projecting toward the rotor (2). A winding (40) is wound around every other magnetic pole tooth (31).
