Provided is a motor system adapted for modern society, which does not use a rare-earth magnet, improves a torque weight ratio by approximately one digit in comparison with the conventional motor, and has transfer efficiency of 90% between electric energy and rotational energy. A stator (1) has a dual-ring tooth-groove iron core, which has magnetic pole surface on both side surfaces and receives coils of basically two-phase structure divided to be multiplexed, with divided coils being interconnected. A rotor (2) is formed to be capable of rotating while holding eight sets of attraction poles having magnetic pole surfaces on both ends, with each set of attraction poles forming four air-gap-facing surfaces by positioning the dual-ring tooth-groove iron core between the attraction poles so that both side surfaces of the dual-ring tooth-groove iron core face the attraction poles via an air gap (6). Magnetic energy accompanying coil switching can be reduced to one part per dozens through the dual effect of reduction owing to coil division and dispersion owing to interconnection. The torque weight ratio can be improved approximately by one digit through synergistic effect of torque increase owing to integration of magnetomotive forces by interconnection, torque increase owing to composite structure of the attraction poles, and weight reduction of the iron core.
