ABSTRACT:
The multiphase step motor is capable of reducing vibrations of a rotor and torque ripples in spite of switching current flowing through stator coils. Stator units are divided into 2n (n is an integer one or more) per one phase and coaxially layered, and the stator units of the same phase are plane-symmetrically layered with respect to a plane perpendicular to an axial center of a stator.
