<P>PROBLEM TO BE SOLVED: To provide an axial gap type electric motor capable of further increasing torque. <P>SOLUTION: A pole fixing side magnetic pole piece is aligned in a circumferential direction coaxial to an output shaft, and pole fixing side opposite faces forming an N-pole and an S-pole are alternately arranged in the circumferential direction coaxial to the output shaft. A pole transition side magnetic pole piece is aligned in a circumferential direction, and passes opposite to the pole fixing side magnetic pole piece on pole transition side opposite faces 42. Magnetic poles transits on the pole transition side opposite faces 42. An electric angle of a projection image on the pole fixing side opposite faces projected on a third imaginary plane parallel to a first imaginary plane, and an electric angle of a projection image of the pole transition side opposite faces 42 projected on the third imaginary plane are set to a numeric value relationship for establishing a maximum value of an effective magnetic flux on a circumferential line coaxial to the output shaft. <P>COPYRIGHT: (C)2013,JPO&INPIT |
