Abstract:
The invention relates to a flywheel including a rotation shaft comprising two magnetic bearing motors. The flywheel is characterised in that the constituent elements thereof are made from non-ferrous materials, the shaft (A) comprising two magnetic bearing motors (1, 1bis), one extending from the other, said two bearing motors (1, 1bis) being offset angularly in relation to one another. The flywheel is also characterised in that an active or passive stop (13) is disposed between the two bearing motors (1, 1bis), said stop (13) acting on the rotor (3, 3bis) and stator (4, 4bis) parts of each bearing motor (1, 1bis), a housing (10) being provided in the shaft (A) between the first and second bearing motors (1, 1bis) for receiving the stop (13).
