Rotor for a rotary electrical machine having a superconductive field winding

摘要

A rotor for a rotary electrical machine having a superconductive field winding, wherein thermal resistance means is arranged at contact parts between a damper, which is so disposed as to cover the superconductive field winding, and a damper support which supports the damper from the inner side thereof. A plurality of protuberances are formed on either said damper support or said damper for restricting heat flow between said damper and said damper support. It is possible to cause a cooling medium to flow through interstices which are defined at the contact parts between the damper and the damper support.
