Patent Images
1. A method for reducing ionization and plasma formation in a high-voltage flywheel energy storage system comprising:
- providing a flywheel in a flywheel housing;
drawing a partial vacuum in the flywheel housing;
providing a motor/generator, the motor/generator having a rotor connected to the flywheel and a stator including, a motor winding;
preventing plasma formation in the motor winding by isolating the motor winding, from the partial vacuum in the flywheel housing,wherein the motor/generator is retained in a motor/generator housing adjacent the flywheel housing,wherein a fluid passageway extends between the flywheel housing and a portion of the motor/generator housing, andwherein an interior pressure of a second portion of the motor/generator housing is ambient air pressure.
