摘要： A stator includes a stator-core having slots and teeth, and a back-yoke having convex and concave portions. The convex portions are partially inserted into the slots, and the concave portions receive the teeth. The teeth include tip portions whose circumferential widths become larger along a radial direction from the inside to the outside of the stator. The back-yoke includes convex portions whose circumferential widths become larger along the radial direction from the outside to the inside of the stator. The tip portions and the convex portions have substantially the same shape. The length of a joint portion between the tip portion and the convex portion, the circumferential width of the tooth corresponding to a tip surface of the convex portion, the width of a root portion of the tooth, and the circumferential width of the convex portion corresponding to a bottom face of the concave portion are substantially the same.

摘要： A synchronous machine comprises a stator and a rotor that faces the stator and rotates on a shaft thereof in a circumferential direction. The rotor has magnetic salient poles that generate reluctance torque and magnet-originating magnetic poles that generate magnet torque by using permanent magnets embedded in the rotor. The machine comprises means for shifting a magnetically substantial central position of magnetic flux emanating from the permanent magnets in the circumferential direction, by an electrical angle π/2 plus a predetermined angle Δθ, from a reference position taken as a central position between paired magnetic salient poles composing each magnetic pole of the machine among the magnetic salient poles. Hence a maximum amplitude of a sum between a harmonic component of the magnet torque and the reluctance torque is changed from that obtained at the reference position without the shift.

摘要： In a reluctance rotary electric machine, a movable part is arranged opposing part of an alignment of a plurality of stator poles to be movable in a predetermined direction. In the movable part, at least one pair of salient poles is configured to magnetically couple to the excited at least one first pair of the plurality of poles so as to form a first magnetic flux in loop thereamong. A segment magnetic-path portion is arranged to be magnetically separated from the at least one pair of salient poles. The segment magnetic-path portion works to magnetically couple therethrough between the at least one second pair of the plurality of stator poles so as to form a second magnetic flux in loop thereamong. The first magnetic flux and second magnetic flux create a reluctance force to move the movable part in the predetermined direction.

摘要： A vehicle alternator is disclosed including a metallic frame supporting a stator having an armature winding and a rotor having a field winding. A rectifying unit is fixedly mounted on the frame for rectifying an alternating current voltage induced in the armature winding upon rotation of the rotor and comprises a stack of a positive-electrode radiating fin, carrying thereon a positive-electrode rectifier element, and a negative-electrode radiating fin, carrying thereon a negative-electrode rectifier element, between which a heat conducting sheet having insulation property is intervened. The frame carries thereon an insulating cover for covering the rectifying unit. The cover includes an encompassing section that collectively encompasses the positive-electrode rectifier element and an associated neighborhood to prevent the cooling wind drawn to an inside of the cover due to rotation of the cooling fan from directly impinging upon the positive-electrode rectifier element.
