Abstract: A power system for providing an uninterruptible power supply to an external load has a first motor adapted to be connected to a source of power, a flywheel/generator adapted to supply power to the external load, a standby generator switchably electrically connected to the flywheel/generator, and a second motor drivingly connected to the generator/motor and to the internal combustion engine. The second motor is electrically connected to the power supplied by the flywheel/generator. The first motor is drivingly connected to the flywheel/generator. The flywheel/generator is electrically isolated from the source of power. The standby generator has an internal combustion engine that is driving connected to a generator/motor. The generator/motor is adapted to supply power to the flywheel/generator or the external load upon a change in power supplied by the flywheel/generator or the source of power. The second motor is an AC squirrel cage induction motor.

Abstract: Uninterruptible Power Supply system comprising motor generator means for conditioning electric power; backup generator means including an internal combustion engine having electrically driven starter, providing backup electric power; electrical switch means, said switch means being electrically connected to power mains and to the backup generator means' electrical output and the motor generator means' electrical input for selectively switching power from the electric means and the backup generator to the motor generator means; starter switch means electrically connected to the motor generator means' output and electrically connected to the input of the starter system of the backup generator means, for switchably connecting the motor generator means' electrical output to the starter system means' input.

Abstract: Permanent magnets are mounted within an electrical machine in a pitched saw-tooth pattern around the rotor shaft. This focused flux configuration provides for improved magnet mounting strength without resort to bonding or taping; provides improved rotor and stator cooling by access to the axial generator air flow; and provides for a simpler and more easily manufactured design. A laminated version of this basic structure provides for reduced surface losses and self-heating.
