A hybrid excitation machine comprising a rotor having first and second rotor cores with a gap between in an axial direction, wherein first magnetic poles excited by a permanent magnet and second magnetic poles not excited by the permanent magnet are alternately arranged in a circumferential direction in each rotor core. The first magnetic poles of the first and second rotor cores have different polarities, and the first magnetic poles of one rotor, core face the second magnetic poles of the other rotor core in the axial direction. A stator generating a magnetic field rotating the motor is placed radially outward of the rotor and an exciting coil exciting the second magnetic poles is placed in the gap, wherein the stator has, in the axial direction, first stator cores on both sides and a second stator core having lower magnetic resistance than the first stator core, in a center. |
