Patent ID: 6956311

Claim:
A magnetic motor comprises a rotor having permanent magnets and rotatably disposed about an axis of rotation, a magnetic sensor disposed at a periphery of the rotor, a plurality of electro-magnetic coils, and control means which controls electric current to the electro-magnetic coils based on detection of magnetism from the permanent magnets by means of the magnetic sensor, the rotor being equidistantly divided in a circumferential direction into a plurality of regions, each region comprising a portion wherein a plurality of permanent magnets are disposed and a portion wherein no permanent magnets are disposed, each permanent magnet being disposed inclined against a radial line extending outwardly from the rotating axis, the rotor is a solid circular member made of non-magnetic body, said circular member has recesses or holes formed therein for accommodating therein said plurality of permanent magnets inclined against radial lines, said plurality of permanent magnets are accommodated in said recesses or holes, and the portion of the rotor where the plurality of magnets is disposed opens radially outward.
