Abstract
A superconducting motor including a rotor, a heat sink, and a bearing. The rotor includes a superconducting winding formed from a superconducting material. The heat sink is positioned within the superconducting motor to absorb heat produced by the superconducting motor. The bearing includes an inner race, an outer race, and a rolling element. The bearing rotatably supports the rotor and is thermally connected to each of the rotor and the heat sink to transfer heat from the rotor to the heat sink. The rolling element is formed from a material having, at 25 K, a thermal conductivity of 20 W/mK or more and an ultimate tensile strength of 650 MPa or more. The rolling element may be formed from a copper alloy.
