摘要： A generator comprises a pair of coaxially aligned rotors including an inner rotor disposed within an outer rotor that combine to form a magnetic field and armature pair. First and second prime movers rotate the rotors in opposite relative directions such that electricity is produced from relative rotation of the magnetic field and armature. First and second flywheels are connected to or integral with the rotors to rotate therewith. Each flywheel has a magnetic circumference. One or more magnetic supports are arranged relative to the circumference to cause at least one vertically acting magnetic force to be exerted on the circumference to support the flywheel's weight. A pair of magnetic stabilisers are arranged on respective opposed lateral sides of each flywheel. The stabilisers cause opposed horizontally acting magnetic forces to be exerted on the flywheel's circumference to impede lateral movement of the flywheel to stabilise the flywheel.
