Abstract
A rotor for a synchronous machine is disclosed comprising: a rotor core; a super-conducting coil winding extending around at least a portion of the rotor core, said coil winding having a coil end section adjacent an end of said rotor core, and a coil support bracing said end section and being thermally isolated from said rotor core.
Claims27
In a synchronous machine, a rotor comprising:
- a rotor core;
- a super-conducting coil winding extending around at least a portion of the rotor core, said coil winding having a coil end section adjacent an end of said rotor core, and
- a coil support bracing said end section and being thermally isolated from said rotor core.
A method for supporting a super-conducting coil winding on a rotor core of a synchronous machine comprising the steps of:
- a. bracing an end section of the coil winding with an end coil support;
- b. assembling the coil winding, end coil support and rotor core;
- c. attaching a rotor end shaft to said rotor core;
- d. thermally isolating the coil support from the rotor core and shaft.
