摘要:
A rotary electrical machine includes a rotational shaft supported by a housing for rotation about an axis, a rotor coupled with the rotational shaft, and a stator fixed to the housing and oriented to face the rotor. A rotor position changing mechanism moves the rotor in an axial direction of the rotational shaft using a portion of a torque transmitted between the rotational shaft and the rotor as a driving force. The rotor position changing mechanism controls the strength of the magnetic field between the rotor and the stator by moving the rotor toward or away from the stator.

A rotary electric machine includes a stator including a plurality of teeth which are each wound up by a coil and a stator yoke core connecting the respective teeth, and a rotor provided with magnets disposed so as to oppose to the teeth, respectively, with a space therebetween. Each of the teeth has a surface opposing to the magnet of the rotor, and the opposing surface is formed with a protruded portion at substantially central portion thereof in the circumferential direction of the stator.

A rotary electric machine includes a stator including a plurality of teeth, a coil wound around each tooth, and a stator yoke core that connects the respective teeth, the teeth and the stator yoke core integrally fixed by a molding resin. The rotary electric machine also includes a rotor with a plurality of magnets that face the teeth, the magnets and teeth separated from each other by a space therebetween. Each of the teeth comprises a head portion facing opposite the magnets, a coil wind-up portion around which the coil is wound up, and an insert portion that can be inserted into the stator yoke core, the insert portion including a groove formed in a portion of the insert portion that protrudes from the stator yoke core, where the groove is fillable with the molding resin to inhibit the teeth from disengaging from the stator yoke core.

A rotary electric machine comprises a stator including a plurality of teeth which are wound up by coils and a stator yoke core connecting the respective teeth, and a rotor provided with magnets disposed so as to oppose to the teeth, respectively, with a space therebetween. Each of the teeth (tooth) is formed into T shape by laminating a plurality of magnetic steel plates and has a head portion and a leg portion, the head portion being a wider portion of the T-shape which is opposed to the magnet, the leg portion including a coil wind-up portion which has a substantially constant width and an insert portion which is inserted into the stator yoke core, and the coil wind-up portion is formed with a plurality of fitting portions for fitting and fixing the laminated magnetic steel plates together, the fitting portions being arranged so as to align along a center line of the coil wind-up portion.

An inlet/outlet pipe extending downward from a bottom face of a body for a ladle is bent at its tip end into an S-shape in an intermediate portion of the pipe, and its tip end is located at a level higher than that of the bent portion. When a negative pressure in the ladle body is increased, a height of range of a molten metal is increased before and after an occurrence of disturbance in the ladle body, so that the negative pressure in the ladle body is made balance with a weight of the molten metal. Thereby, the molten metal is measured and held at a constant volume in the ladle body.
