DISK SHAPED MOTOR WITH ROTATOR FULLY SEPARATED FROM STATOR

摘要

PURPOSE: A disk shaped motor with rotator fully separated from stator is provided to be capable of rotating a rotator by rotary magnetic field by separating a rotator from a stator. CONSTITUTION: A stator includes a plurality of projective iron cores(11) where a coil(14) is wound and a stator back iron core(13) integrated with the projective iron cores(11) so as to form a magnetic flux circular circuit(30). A rotator includes a disc magnet(22), a rotator back iron core(21), and a shaft(23). The disc magnet(22) consists of 2-8 magnets. The rotator back iron core(21) supports the disc magnet(22) and forms the magnetic flux circular circuit(30). The shaft(23) is extended from a center iron core so as to transfer an electric power.
