Abstract
PURPOSE: To eliminate occurrence of eddy current loss at the retainer ring for a field coil end portion by high frequency magnetic flux incident to main magnetic flux by constructing in double layers high tensile strength metal at the inside of the ring and highly conductive metal at the outside of the ring.
CONSTITUTION: The retainer ring 6 for retaining field coil end portion against centrifugal force is constructed in double layers by high tensile strength alloy steel 6b at the inside and highly conductive metal 6a at the outside. Even if main magnetic flux thus operates the ring 6, high frequency magnetic flux incident to the main magnetic flux is cancelled in the outside ring 6a. Accrodingly, it reduces the eddy current loss occurred at the retainer ring 6 to enable to restrict the temperature increase of the ring 6. In addition, the inside ring 6b maintains the mechanical strength of the ring 6.
