Abstract: Plural auxiliary devices such as a water pump and a generator coupled to a serpentine belt-drive system are driven by an internal combustion engine mounted on an automobile vehicle. The generator is divided into a first generator having a pulley in which a one-way clutch is installed and a second generator having a usual solid pulley. Fluctuations in the belt tension caused by changes in instantaneous rotational speed of the internal combustion engine are suppressed or reduced by the one-way clutch installed in the pulley of the first generator. An inertia torque of a rotor of the first generator may be made higher than that of the second generator because effects of the inertia torque on the belt tension fluctuations are alleviated by the one-way clutch.

Abstract: This invention relates to a rotational speed control system including a plurality of motor drivers for driving motors, and the object thereof is to drive a plurality of motors at the same rotational speed without depending on the number of motor drivers and without depending on the characteristics of each motor driver. A remote controller 31 and a motor driver 202 are connected to a motor driver 201. The motor drivers 201 and 202 control motors M11 and M12 at a prescribed rotational speed, respectively. A rotational speed instructing signal 91 indicative of the rotational speed is supplied from the remote controller 31 to the motor driver 201, and further supplied from the motor driver 201 to the motor driver 202. Because the rotational speed instructing signal 91 indicates a rotational speed which is transmitted in a digital value between the motor drivers 201 and 202, both of the motors M11 and M12 are driven at the rotational speed indicated by the rotational speed instructing signal 91.

Abstract: An electric energy storage and distribution system for a fluid-driven propeller, the propeller being connected to drive an AC generator, includes a planetary gear system by means of which rotation of the propeller is transferred to the AC generator motor, via a ring gear and a sun gear attached to a DC generator/motor, the DC generator/motor being connected to a battery. When the speed of the propeller is insufficient to drive the AC generator at a desired frequency and voltage, the DC motor is driven by the battery to either assist rotation of the propeller or the propeller can be braked such that the DC motor alone drives the AC generator. When an excess propeller speed is obtained, the propeller drives both the AC generator and the DC generator, the DC generator charging the battery. Conversely, when excess power is available through the power grid, the AC generator can be used as a motor to drive the DC generator via the ring gear, planetary gear, and sun gear to charge the battery.

Abstract: An uninterruptible rotating power supply incorporates a sensor of motion and distortion of a stator during interruptions of normal power supply acting on the stator within a synchronous motor, which normally rotates an alternator supplying power to the electric load. When a distortion (unacceptable normal power supply) is sensed, transient power is supplied by a flywheel and hydraulic motor driven by hydraulic fluid stored under pressure in a reservoir. Long term emergency power is supplied by a diesel engine driving the generator or hydraulic pump. The dual supply of transient power allows redundancy for large amperage critical applications or downsizing of flywheel to minimum levels in less critical applications or where a portion of the load is not critical.
