Abstract
The invention is a motor/generator that includes a motor/generator housing that encloses a rotor assembly, which rotates a shaft, and a stator assembly that remains stationary, and where the motor/generator is inside a vacuum chamber, which, during normal operation, is evacuated of gas and operates at a lower air pressure than atomospheric air pressure, and a cylindrical vacuum barrier between the rotor assembly and the stator assembly that together with the motor generator housing partitions the motor/generator into an interior rotor volume and an exterior stator volume, enabling the rotor volume and stator volume to operate at different atmospheric pressures.
