Synchronous machine rotor and method of making a synchronous machine rotor

摘要

A rotor (14) is disclosed for a synchronous machine (10) comprising: a rotor core (22); a super-conducting coil winding (34) extending around at least a portion of the rotor core, said coil winding having a side section (40) adjacent a side of the rotor core; at least one tension rod (42) extending through a conduit (46) in said rotor core; at least one tension bolt (43) extending between an end of the tension rod and abutting the side section of the coil winding; and a channel housing (44) attached to the tension bolt and the coil winding.
