Abstract
A stepper motor includes: a rotor including a rotor core and a permanent magnet, the rotor core including a plurality of teeth; and a stator arranged around the rotor while being spaced apart from the rotor and including a plurality of magnetic pole teeth, the magnetic pole teeth including a plurality of teeth and projecting toward the rotor. A winding is wound around every other magnetic pole tooth. A phase of the teeth of the magnetic pole teeth with no winding therearound is shifted from a phase of the teeth of the other magnetic pole teeth.
