Abstract
Abstract The present device is power system for providing an uninterruptible power supply to an external load comprising a flywheel generator, a first motor, a standby generator, and a transfer controller. The flywheel generator is adapted to supply energy to the external load. The first motor is drivingly connected to the flywheel generator. The first motor is adapted to be connected to a source of power external to the power system. The standby generator is electrically connected to the first motor. A standby motor is drivingly connected to the standby generator. The transfer controller is adapted to switchably interconnect the first motor to the source of power and to interconnect the standby generator to the first motor. The flywheel generator comprises a flywheel having a vertical axis, a shaft connected to the flywheel, and a synchronous A.C. generator arranged about the shaft. The standby motor is a diesel engine having an electric starter. A voltage regulator is electrically connected about the output of the flywheel generator.
