Abstract
A high power density synchronous machine is disclosed comprising: a stator having conventional stator coils arranged in an annulus around a vacuum cylindrical cavity; a magnetically saturated cylindrical magnetic solid rotor core; a race-track super-conducting coil winding extending around the rotor core, and a coil supportextending through the core and attaching to opposite long sides of the coil winding.
Claims19
A synchronous machine comprising:
- a stator having stator coilsarranged in an annulus around a vacuum cylindrical cavity;
- a cylindrical magnetic solid rotor core;
- a super-conducting coil winding mounted on the rotor core, and a coil support extending through the core and attaching to opposite long sides of the coil winding.
A synchronous machine having a rotate capacity of at least 100 MVA comprising:
- a stator having stator coils arranged in an annulus forming a vacuum rotor cavity;
- a cylindrical solid rotor core having a pair of planer sections on opposite sides of the core and extending longitudinally along the core, and
- a super-conducting coil winding extending around at least a portion of the rotor core, said coil winding having a pair of side sections adjacent said planer sections of the core.
