Abstract:
A magnetic circuit for a rotating apparatus having a parallel structure or a skew structure of magnet pole pieces of magnets or armatures with respect to a shaft, comprising:a rotating shaft; a plurality of supporters fixedly mounted in a perpendicular direction to the circumference of the rotating shaft; a rotor having a plurality of magnets rotated by attraction force and repulsion force of a magnetic field, each magnet having a magnet pole piece being arranged in parallel with respect to the shaft and located on an end of one of the plurality of supporters; and a plurality of armatures (stators) each having a coil and opposing pole faces, each coil being mounted at an interval outside the rotors and receiving induced magnetic flux of the rotors, and said coil pole faces being arranged in skew with the rotating shaft.
