The second section is electrically connected to the first lead, and rigidly connected to a linear displacement device enclosed entirely within the vacuum container. The linear displacement device linearly displaces the second section relative to the first section, so that the first section contacts the second section thereby electrically connecting the first and second sections, or by creating a gap between the first section and second section thereby electrically disconnecting the first section from the second section.

A superconducting brushless communtatorless DC electrical motor and generator includes a machine housing, a first stationary member, a first rotating member, a second stationary member, a second rotating member, a shaft, a power transfer device and a cooling assembly. The superconducting brushless communtatorless DC electrical motor and generator produces a magnetic field where at least one coil side produces main driving torque and the remaining coil sides produce torque that cancels torque produced by the remaining coil sides in a direction opposite the main driving torque. This prevents the remainder of the coil sides to produce torque in the direction opposite the main driving torque and producing continue rotation.
