CROSS-COUPLED COMPOSITE MOTOR, CROSS-COUPLED COMPOSITE POWER GENERATOR, AND CROSS-COUPLED COMPOSITE LINEAR MOTOR

WIPO Patent Application WO/2017/122814

A1

Provided is a reversibly transforming motor system, adapted for modern society, that does not utilize a rare earth magnet, yields a torque/weight ratio improved by about one order of magnitude over conventional motors, and has an electrical energy and rotational energy efficiency of about 90%. A stator (1) is housed in a dual-ring toothed iron core having pole surfaces on both sides thereof, such that coils are cross-coupled in a divisionally multiplexed manner based on a two-phase configuration. A rotor (2) is configured so as to be capable of rotating while holding eight sets of suction poles having pole surfaces on both ends thereof, the poles being disposed around the dual-ring toothed iron core, across a gap (6), so as to sandwich the area between the iron cores of the dual-ring toothed iron core therebetween and form four surfaces facing each other across the gap. The magnetic energy accompanying coil switching can be reduced to a few tenths through the two-fold effects of the reduction yielded by coil division and the distribution yielded by cross-coupling. The torque/weight ratio can be improved by roughly one order of magnitude through the synergistic effects of the increase in torque yielded by the integration of magnetomotive force that results from cross-coupling, the increase in torque yielded by the composite structure of the suction poles, and the reduced weight of the iron core.
