Abstract
A dynamoelectric machine that can suppress increases in rotor inertia to extend belt service life and increase field magnetomotive force to increase output. In the dynamoelectric machine, first and second magnetic guidance members are fitted into first and second holding grooves that are disposed so as to extend axially on facing portions of first and second trough portions radially outside inner wall surfaces, and are disposed so as to span over first and second trough portions. First and second permanent magnets that are magnetically oriented in a reverse direction to a magnetic field that originates from a field coil are fitted into and held by interfitting grooves of the first and second magnetic guidance members so as to face inner circumferential surfaces near tip ends of second and first claw-shaped magnetic pole portions so as to have a predetermined clearance.
