<p><P>PROBLEM TO BE SOLVED: To provide an axial gap motor effectively utilizing a permanent magnets and magnetic materials equipped with a rotor to increase the output, while reducing the eddy-current loss generated at energization, and improving the operating efficiency. <P>SOLUTION: The rotor is constituted of magnetic poles 31,...,31, magnetic material poles 32,...,32, and a rotor frame 33. The magnetic pole comprises a substantially fan-shaped permanent magnet piece 41 magnetized in the thickness direction or in the direction of a rotating shaft O, and a pair of substantially fan-shaped magnetic material 42 supporting the permanent magnet piece 41 at both sides in the thickness direction. Each of the permanent magnets 41,...,41 in a plurality of magnetic poles is set with the same magnetizing direction. A plurality of magnetic pole through holes 45,...,45 is equipped in the magnetic material pole 32, with the holes passing through the same direction as the rotation shaft O; each magnetic-pole through hole 45 has a sectional shape long in a radial direction with respect to the direction of the rotating shaft O; and the plurality of magnetic-pole through holes 45,45 is disposed at a predetermined interval in the peripheral direction. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
