Abstract
The present invention provides a dynamoelectric machine that enables permanent magnets to be held stably in trough portions that are formed on portions of a yoke portion that are positioned between adjacent claw-shaped magnetic pole portions. In a dynamoelectric machine according to the present invention, first and second magnet holders are disposed so as to span first and second trough portions that are formed on portions of first and second yoke portions that are positioned between circumferentially adjacent first and second claw-shaped magnetic pole portions, and first and second permanent magnets are held by the first and second magnet holders so as to face inner circumferential surfaces near tip ends of the claw-shaped magnetic pole portions so as to have a predetermined clearance.
