Abstract: A device for converting or transducing wind power into other power, such as electric power. A wheel is rotatably journalled on a shaft (8) in the upper region of a tower (1). The wheel has a number of blades (9) between the shaft (8) and an outer annulus (10) which is located a distance from the shaft (8). The tower (1) is rotatable for positioning the wheel substantially at right angles to the prevailing direction of the wind. A transmission device (26) extends between the annulus (10) of the wheel and the foot of the tower for transducing the transmitted wind power into other power.

Abstract: A wheel having an accelerating electricity charging device includes a wheel, an accelerating gear set, a shaft sleeve, a generator, and a shaft. The wheel comprises an inner gear. The accelerating gear set comprises a pair of driving gears, a driven gear and a fixing plate. The driving gears mesh with the driven gear and are secured on the fixing plate. The shaft sleeve is inserted through the driven gear. The generator comprises a magnet and a coil. The magnet of the generator is secured to one end of the shaft sleeve with the shaft inserting through the shaft sleeve and the magnet inserted through the coil. The shaft is provided with engaging surfaces engaged with the hole of the fixing plate.

Abstract: A claw-pole permanent-magnet stepping motor includes a pair of cases containing two or more inductors in symmetrical arrangement with multiple claw poles. The case unit has an oval shape having thin flat side walls or thin stepped side walls and connecting thick arcuate surfaces operating to resist external flux leakage from the motor and eliminating magnetic circuit obstructions. The cases, side walls, and inductors allow the motor to have a width to length ratio from about one to one to about one to two thus allowing a reduction in size and a low profile design while retaining available output torque.

Abstract: In a connection portion of a stator winding, conductor wires extending outward from a slot pair separated by a predetermined number of slots are joined such that end portions of conductor wires extending outward from addresses of the slot pair separated by three or more addresses are joined together (a distant-address joint portion), and end portions of conductor wires in the slot pair separated by two or less addresses are joined together (a near-address joint portion). The distant-address joint portion is offset in a circumferential direction relative to the near-address joint portion.

Abstract: An engine includes an engine body and a generator. The engine body has a stator bracket mounted to the cylinder block. The generator incorporates a rotor flywheel and an armature assembly consisting of armature legs. Various metal plates with high magnetic permeability make up the armature legs and are securely fastened in a radial manner to the similar plate made of aluminum. The stacked armature legs surround the crankshaft and are mounted to the stator bracket. The preferred heat conduction path travels from the armature legs through the aluminum plate on onto the stator bracket in order to improve the heat dissipation of the generator.

Abstract: In a machine housing of the prior art, the bearing plate must be secured to the tubular element by means of one additional assembly step. In a machine housing of the invention, the bearing plate is secured in the tubular element by pressure, and simultaneously an axial play of a shaft in the machine housing can be adjusted.

Abstract: A rotational sensor of a motor includes a sensor magnet and a sensing element. The sensor magnet is secured to a driving-side rotator of a clutch, which is connected to a rotatable shaft of the motor, to rotate integrally therewith. The sensing element measures a rotational speed of the sensor magnet. Furthermore, the sensing element is secured to a motor case in such a manner that the sensing element opposes the sensor magnet.

Abstract: A vehicle AC generator includes a rotor, a stator having a stator core and a stator winding, a pair of front and rear frames and electric components including a rectifier unit and other electrical parts disposed rear of the rear frame. The stator winding is connected to the rectifier unit by one of means of welding, soldering and clamping, and the rear frame has a stay having a fixing surface disposed rear of the electric components. Therefore, it is not necessary to provide a space for screwing a screw bolt to connect the stator winding and the rectifier unit. Because cooling air is discharged from a discharge window along the stay, heated air will not return to any of air intake window.
