Vernitron Corporation

Neil N Saldinger

A brushless DC motor is provided comprised of a steel ring rotor on which rare-earth magnets are fastened and a segmented stator having a comb-like core for each segment that extends at each end beyond its support structure so phase windings in slots in those extended ends can be provided to the same extent as for all other slots in the comb-like segment, thereby producing substantially the same torque on the rotor over the extended ends as over the central portion of the stator segment. Due to their high coercivity, the rare-earth magnets can operate into air circuits between stator segments without demagnetization, returning to their high flux levels upon re-entering a stator segment.
