Abstract: The variable-field rotary electric machine includes: a rotor that is rotatably integrated with a shaft while an axis of the shaft is used as a rotation axis and includes a movable iron core and a displacement mechanism configured to displace the movable iron core in an axial direction of the rotation shaft. The displacement mechanism includes: a cylinder unit including a cylinder chamber to retain hydraulic fluid according to a rotor speed, a piston member connected to the movable iron core, and a sealer member provided at the piston member. The the piston member and the movable iron core are displaced in the axial direction of the rotation shaft in response to an increase or decrease in an amount of the hydraulic fluid in the cylinder chamber.
Abstract: An electromagnetic motor having a frame, and at least one disc rotatably mounted to the frame. At least one permanent magnet is mounted on the disc, and at least one electromagnet is mounted to the frame in magnetic proximity to the at least one permanent magnet. A battery is electrically coupled to the motor for powering the at least one electromagnet. A switch controls electrical power between the battery and the at least one electromagnet, and a sensing means is provided for controlling the switch to activate the at least one electromagnet with respect to the at least one permanent magnet to cause the at least one disc to rotate. Preferably, a generator is mechanically coupled to the motor and electrically coupled to the battery for generating electrical power to the battery, and a renewable energy source such as a photovoltaic cell is electrically coupled to the motor to supplement any net electrical loss.
Abstract: A vehicular charging generator provided with a one-way clutch having a clutch inner installed to a shaft of a rotor and a clutch outer interposed between the clutch inner and a pulley driven by a power unit for driving a vehicle and transmitting a power only in one rotational direction from the pulley to the shaft, wherein a male screw is formed on the shaft, a female screw is formed on an inner peripheral portion of the clutch inner and the female screw is engaged with the male screw thereby fixing the clutch inner to the shaft.
Abstract: A device for driving an electrical current generator for use in a motorcycle is disclosed. The electrical current generator is housed within a casing separatedly provided from an engine unit housing an engine. A power transmission means connecting between an output shaft of the engine and a rotary shaft of the generator is provided within a confined space outside of the engine unit. The confined space is defined by a crank casing, a rising flange integrally provided to the crank casing and a cover member. The power transmission means includes a first pulley mounted on one end of the output shaft of the engine, a second pulley mounted on one end of the rotary shaft and a V-belt mounted between the first and second pulleys. The rotation speed ratio of the rotary shaft to the output shaft is changeable in response to the rotation speed of the output shaft.
Abstract: A drive apparatus for a vehicle mounted generator is provided wherein such vehicle has a driver shaft and a driver sheave detachably fixed thereto with the drive apparatus comprising an adjustable pivot support supporting the generator on the vehicle, a driven sheave detachably fixed to the rotor of such generator, at least one belt operatively connected between the driver sheave and the driven sheave, and a device yieldingly moving the generator about the pivot support to thereby move the driven sheave away from the driver sheave and place a substantially constant yielding tension on the belt to assure that the driven sheave and generator are driven in an optimum manner.
Abstract: An electric generator arrangement has at least two wind or water wheels rotatably mounted on a common stationary shaft and coupled such that they rotate in opposite directions with a given ratio or a progressively variable ratio. The wheels carry the two cooperating parts of a first generator and may also each carry the rotor of a second or third generator cooperating with a stator on the shaft, the field excitation or current loading of the second and/or third generator being used to control the speed of the wheels.
