A flywheel kinetic energy recovery apparatus 14 for the recovery, storage and release of energy in vehicles, comprises a first flywheel 6 and a second flywheel 4. Each of the first and second flywheels 6, 4 includes a rotor 7, 4 disposed about a set of coils 12, 5, the rotors being supported to rotate about said coils. The rotor 7 of the first flywheel 6 is attached to a flywheel element 6a, and the second rotor 4 is supported on a magnetic bearing, the magnetic bearing being provided by a magnetic field generated about the coils 12, 5 when an electrical current is passed through the coils. By supporting the flywheel 4 in this manner, friction losses are minimized. |
