Abstract

PURPOSE: In addition to eliminate permanent magnet from rotor, arrange high permeability members for the purpose to increase the length of permanent magnet and the effective gap area of flux return path and to prevent knockdown, and to improve pull-in torque at step driving time by reducing rotor inertia.
