Abstract
An electrical motor/generator is provided with at least one of a superconducting rotor, a stator including dovetailed winding dividers, and a stator cooling arrangement with at least one cooling tube per winding slot positioned such that each armature winding is thermally coupled to at least one cooling tube.
Claims11
A rotor for an electrical motor/generator, comprising:
- at least one cryogenic temperature coil wound around a coil form, the coil form being fixed to a pole tip of the rotor in such a manner as to accommodate thermal contraction of the at least one cryogenic-temperature coil relative to the pole tip wherein the coil form is fixed to the pole tip of the rotor by at least one bracket slidably attached to the pole tip.
