Turbogenerator rotor damping winding fixture device

摘要

The fixing device is used to secure a rotor damping winding in the pole zone of a permanent magnet rotor (14) via wedges (20) integral with the rotor permanent magnets (16). Each of the permanent magnets has a T-shaped cross-section and extends over the full length of the rotor to cover each of the rotor pole zones, the width of each permanent magnet corresponding to 1/6 of the full periphery of the rotor
