Abstract: A clutch actuator comprises a motor having a motor shaft. A worm shaft is formed with a threaded section. A worm wheel meshes with the threaded section of the worm shaft. An output rod reciprocates in an axial direction to disengage and engage a clutch. A crank shaft converts rotational motion of the worm wheel to reciprocating motion of the output rod. The motor shaft and the worm shaft are coupled by a spline connection.

Abstract: A number of embodiments of rotating electrical machines and methods for winding them that provides a high space utilization and very effective winding with less likelihood of damage to the insulation of the wire of the winding during the winding process. The arrangement basically does not require the winding needle to be moved back and forth in the slot between the poles but rather employs insulating inserts that are positioned on the axial faces of the poles outside of the gaps for guiding the wire from one end to the other so as to provide the high space utilization.

In one embodiment the insulating insert effectively changes the circumferential length of the coil winding that decreases in an axial direction along their length.

Abstract: An electrical machine having a plurality of pole pieces surrounded by bobbins and upon which individual coil windings are formed. The bobbins are formed by a insulating material in which are embedded electrical connectors that have terminal ends that afford connection to the coil windings and to an external connection for either deriving electrical power in the case the machine operates as a generator or receiving power in the event the device operates as a motor. Thus, cost is reduced and at the same time the device is more compact and more efficiency.

Abstract: A number of embodiments of rotating electrical machines using permanent magnets wherein the cogging torque is substantially reduced as are vibrations caused by magnetic flux variations. This is accomplished by disposing the coil windings in equal circumferential spacing and disposing the associated permanent magnets in non-symmetrical relationship so that the gaps between some of the magnets are different. In addition, the coil windings are such that no two coils of any phase are immediately adjacent each other in a circumferential direction. A method for calculating the optimum spacing is also disclosed.

Abstract: An engine speed control that avoid undesirable transmission conditions such as clutch chattering. This is done by sensing actual conditions, which are likely to result in the undesirable transmission conditions such as clutch chattering and only changing the engine output when these exact conditions are found. The conditions sensed are the determination of excessive acceleration in engine speed or in the speed of a shaft associated with the engine or the degree of rotational variation or rotational acceleration.

Abstract: Several embodiments of permanent magnet type three-phase AC rotary electric machines wherein the phase current flow is formed by parallel circuits formed by a plurality of serial circuits each comprising one or a plurality of stator coils so that electromagnetic voltage or counter electromagnetic voltage generated across opposite ends of the plural serial circuits may be always almost the same. Thus, a circulating current does not flow in the parallel circuits, whereby the efficiency of the rotary electric machine can be improved. Also, since the line current circuit of each of the phases is constituted of a parallel circuit, the current flowing in each of the stator coils is small so that the diameter of the stator coil wire can be small. Thus, the winding of the coils can be improved. Also, the processing of the coil terminals is facilitated and the processed portions of the terminals can be made small, resulting in a compact rotary electric machine.
