Title:
AN ENERGY STORAGE AND CONVERSION APPARATUS
Document Type and Number:
WIPO Patent Application WO1996005646
Kind Code:
A3
Abstract:
An energy storage and conversion apparatus 1 comprisinga containment 5 defining a vacuum chamber 7,a substantially vertical shaft within the vacuum chamber 7,a stator 11 on the shaft 9, anda cylindrical rotor 13 which, in use, is driven by the stator 11 to store energy as kinetic energy of the rotor 13 and acts with the stator 11 as a generator to release energy, wherein the rotor 13 is supported by the shaft 9 via an end cap 29, positioned at the upper end of the cylindrical rotor 13, which engages the shaft 9. The rotor 13 is suspended from a pin bearing 31 which is attached to an end cap 29. The pin bearing 31 sits in a bearing cup 37 mounted in a damper 39 at the end of the shaft 9. A magnet bearing 43 is provided at the lower end of the rotor 13 to assist in positioning the rotor 13 relative to the stator 11.
