摘要： In a side-mount type vehicle alternator, the mounting faces of a larger stay and a smaller stay are arranged such that the fictive line, which runs through the center of a mounting hole on the mounting face of the larger stay and the center of the mounting hole on the mounting face of the smaller stay, is on the outside of an outermost surface of a front frame and a rear frame. Thus, the alternator is lifted up from an engine bracket and it is possible to make a large space. Hot air being exhausted from exhaust windows flows smoothly to the outside of the space.

摘要： A reluctance motor is provided that reduces leaking magnetic flux. To generate magnetic flux between adjacent magnetic poles in a rotor 2, permanent magnets 4 are disposed in approximate centers of split magnetic paths near a borderline area between two magnetic poles in an internal portion of the rotor. Further, each of slots 8 in a stator 1 is wound with a coil of a corresponding phase such that the vector phase and amplitude expressed by the products of the number of coil turns and the amount of passing current, namely, ampere-turns, become almost identical for each of the slots. By reducing leaking magnetic flux according to this arrangement, generated torque can be increased. As the rotor mechanical strength is enhanced, the rotor can be safely driven at a higher speed. A practical motor is obtained that simultaneously achieves improved motor characteristics and reduced torque ripples.
