Abstract: The dual drive electric regenerator (DDER), an electric power regenerative device in which a heavy driven-backend flywheel combination being coupled directly to the drive shafts of a specially designed electric generator with dual drives. The driven flywheel with magnetic Pole pieces attached to its circumference area being rotated by the magnetic forces imparted from a driver flywheel with magnetic Pole pieces attached to its circumference surface and rotated by an electric driver motor with its speed being controlled electronically. The DDER expends less input power than the output power generated by the flywheel combination and converted to electrical power by the said generator. The initial power to start the motor being derived from an internal battery. A part of the output power generated being used as the input power through recharging the battery continually and the rotational process being sustained by completing a power regenerative cycle.

Abstract: Spacecraft electric regenerator, a power regenerative device that generates electrical power to spacecrafts. The device generates its own power by rotating a rotor disc with magnetic Pole pieces attached to its inner bore around an armature coil assembly fixed to a stationary shaft. The rotor disc being rotated to a predetermined velocity by a starter mechanism and the rotation thereafter being maintained under a zero gravity and in vacuum conditions due to the accumulated kinetic energy. To overcome any inherent and imposed retarding forces, the rotation being assisted by transferring the rotational power of an electric driver motor as magnetic power from a driver disc with magnetic Pole pieces attached to its outer circumference surface. The rotation being controlled and maintained by a power control and conversion process in order to sustain the power regenerative cycle.
