<p>A flywheel system having permanent magnets (20) disposed on a flywheel (10) rotating about a shaft (12) is provided with a stator (28) having an outer diameter which is oriented concentrically and shaped conically within a similarly shaped inner diameter of the flywheel (10) (and the magnets (20)). The stator (28) is slidably and rotatably mounted to a shaft (30) thereby allowing a gap (G1) between the stator (28) and the rotor/flywheel (10) to be adjustable. When energy is being provided to (spin-up) or extracted from (spin-down) the flywheel (10), the stator is automatically forced to the left due to torque on the stator (28), thereby causing the gap (G1) to be small to provide strong electromagnetic interaction between the stator (28) and the flywheel (10). Conversely, when the flywheel (10) is freewheeling, the stator (28) is forced to the right by a spring (40) causing the gap (G1) to increase to a distance large enough to minimize electro-magnetic drag on the flywheel (10).</p> |
