ABSTRACT:
A multi-phase stepper motor having an annular permanent magnetic rotor and a plurality of matingly engageable stator phase assemblies around the rotor. Each of the phase assemblies comprises a pair of annular pole pieces including interleaved salient stator poles. The stator pole pieces in each pair are mated together in an opposed relationship to form an annular space between them to receive an energizing winding, and the winding for each pair is of a different phase. Depending upon the number of phase assemblies, the machine can operate in more than two phases. The diameter of the rotor is between about 55 percent and about 75 percent of the motor diameter, and approximately 40 percent more torque is produced than with equivalent sized conventional motors.
