Abstract
A permanent magnet dynamoelectric machine of surface magnet type is configured to have a flanged U-shaped magnet presser made of a conductive metal, and to fix the magnet presser to a rotor core using a fixing member so as to fix a part of an outer periphery of a permanent magnet in a radial direction with a flange of the magnet presser. This ensures the permanent magnet dynamoelectric machine of surface magnet type to be adaptable to large-torque, high-speed and large-capacity.
