Abstract
The invention is to provide an axial gap type rotating apparatus for enabling downsizing and high output by causing the magnetic field to pass across the coils effectively in arranging the magnets and coils to oppose one another in the axial direction of the rotor shaft, in which in arranging pluralities of segment magnets and segment coils radially to oppose one another in the circumferential direction of the rotor shaft, each segment coil is comprised of an air-core coil having a non-winding portion in the center, a segment yoke piece of soft magnetic material is provided in the non-winding portion while being in non-contact with the winding, and the segment yoke pieces are arranged discontinuously in a separate state for each of non-winding portions of a plurality of segment coils.
