    摘要: In a design method for a belt transmission system, tensile forces between pulleys are calculated from a total layout of the belt transmission system, such as a spring constant of a belt, a distance between the pulleys, an initial tensile force, a driving force for the respective pulleys to be calculated from a load of the respective pulleys, and so on. A coefficient of static friction is calculated from the tensile forces at the pulling and un-pulling sides and a contact angle. Then the coefficient of the static friction is compared with a maximum coefficient of the static friction, and it is determined that no slip occurs when the coefficient of the static friction is smaller than the maximum coefficient of the static friction.

    摘要: A vehicular alternator has a stator winding, in which a middle point of one phase winding is connected to a winding finish end of another phase winding in a cyclic manner among the three-phase windings. A Δ-connection portion is formed by a portion between the middle points and the winding finish ends of the respective phase windings and a Y-connection portion is formed by a portion other than the Δ-connection portion. The output characteristic of the vehicular alternator is variable depending on a position of the middle point.

    摘要: A rotary electric machine has two sub-windings shifted by 30 degrees from each other. Each sub-winding is connected to an individual bridge which has MOS transistors on the ground sides. It is possible to supply a charging current even at a low rotational speed by switching the MOS transistors at a high-frequency. The basic components of magnetic force are canceled because of the shifted sub-windings. The switching components of the magnetic forces generated by the switching operation are canceled by switching two groups of the MOS transistors in opposite states. As a result, it is possible to decrease the magnetic noise significantly.

    摘要: The present invention provides a compact, efficient and noiseless alternator for an automotive vehicle which employs a double-layer coil arrangement in a slot for eliminating coil end interference as well as improving the space factor. An automotive alternator comprises a Lundel-type core rotor with 16 poles, and a stator with toothed portions of 96 poles spaced by slots. U-shaped conductor segments are installed in the slots. One portion of the conductor is accommodated in an outer layer portion of a predetermined slot, while the other portion is accommodated in an inner layer portion of a slot phase shifted by an electric angle of 180°. In this manner, all of the slots are separated into the inner and outer layers to accommodate a plurality of conductor segments. These conductor segments are connected only at one side of the stator to form a total of twelve wavy winding coils. These twelve wavy winding coils are divided into three groups each consisting of a serial connection of four wavy windings to constitute one phase of a three-phase stator coil.

    摘要: Leading current or lagging current of an alternator is supplied by a simple structure including short-circuit switch elements. The short-circuit switch elements are connected across output terminals of the alternator three-phase armature windings, and are turned on and off at fixed timings to supply a suitable amount of the leading current to armature windings regardless of the rotational speed. Thus, the leading current can be supplied without phase-leading-capacitors so that the apparatus can be made compact, lightweight and powerful. Even if any of the short-circuit switch elements can not turn off, the battery discharge can be prevented.
