CLAW-TOOTH ROTOR DYNAMOELECTRIC MACHINE

摘要

A synchronous machine having a Lundell-type rotor is provided with a stationary excitation winding positioned at the axial end of the rotor with a continuous annular magnetic flux collector core surrounding the winding. This collector provides a dual, relatively shorter, continuous flux path between alternate poles of the rotor as it sweeps past the flux collector without including the stator yoke or housing in the flux path.
