Title
(EN) AN ENERGY STORAGE AND CONVERSION APPARATUS
(FR) APPAREIL DE TRANSFORMATION ET DE STOCKAGE D'ENERGIE
Abstract
(EN)
An energy storage and conversion apparatus (1) comprising a containment (5) defining a vacuum chamber (7), a substantially vertical shaft within the vacuum chamber (7), a stator (11) on the shaft (9), and a 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).

Un appareil de transformation et de stockage d'énergie (1) comprend une enceinte de confinement (5) formant une chambre à vide (7), un arbre pratiquement vertical se trouvant à l'intérieur de la chambre à vide (7), un stator (11) placé sur l'arbre (9), et un rotor cylindrique (13) qui, en utilisation, est entraîné par le stator (11) afin de stocker l'énergie représentant l'énergie cinétique du rotor (13) et fonctionne avec le stator (11) comme un générateur pour libérer l'énergie. Le rotor (13) est supporté par l'arbre (9) par l'intermédiaire d'un couvercle (29), positionné à l'extrémité supérieure du rotor cylindrique (13), qui vient en contact avec l'arbre (9). Le rotor (13) est suspendu à un palier à aiguille (31) qui est fixé au couvercle (29). Le palier à aiguille (31) se positionne dans une cuvette (37) montée dans un amortisseur (39) à l'extrémité de l'arbre (9). Un palier magnétique (43) est ménagé à l'extrémité inférieure du rotor (13) pour faciliter le positionnement de ce dernier par rapport au stator (11).
