摘要： PROBLEM TO BE SOLVED: To prevent a magnetic resistance between a stator and a rotor from changing depending on the position of the rotor.
SOLUTION: The rotary electric machine is configured so that the thickness direction of a plurality of magnetic plates 121a-121o constituting the stator 120 follows the rotating direction of the rotor 110, and the regions of the plurality of magnetic plates 121a-121s which oppose at least permanent magnets 115a-115j are disposed with a substantially equal spacing in the rotating direction of the rotor 110. Accordingly, even if the rotor 110 rotates to cause a change in the positional relation between the permanent magnets 115a-115j constituting the magnetic poles 115, 116 and the magnetic plates 121a-121o constituting the core 121 of the stator 120, fluxes to be imposed on the respective magnetic plates 121a-121o from the permanent magnets 115a-115j become substantially the same. Thus, the magnetic resistance between the magnetic plates 115, 116 and the core 121 of the stator 120 is substantially the same (as a whole), irrespective of the position of the rotor 110.

摘要： PROBLEM TO BE SOLVED: To provide a permanent magnet type rotating electric machine capable of obtaining a high torque in a low speed range, performing efficient operation even during a high speed, and reducing slide and drag loss at the time of idle rotation.
SOLUTION: The permanent magnets for forming a field flux are buried in a rotor, and a cavity portion is provided toward the axial center side from the permanent magnet. Movable magnetic substances are provided in the cavity to control the field flux crossing an armature winding by mechanically adjusting the position of the magnetic material. When the rotor is at a low speed, each of the magnetic substances is positioned at a portion with low magnetic resistance in the cavity, and the field flux of the rotor surface increases to obtain high torque. When the rotor is at a high speed, the magnetic substance moves to a portion with high magnetic resistance, and the field flux of the rotor surface is decreased to decrease a counter electromotive voltage generated at the armature winding. At the time of idle rotation, the magnetic substance is positioned at the portion with high magnetic resistance in the cavity, and the flux density of the stator is decreased together with the field flux, thus reducing the slide and drag loss.

摘要： PROBLEM TO BE SOLVED: To provide a radial iron core which is used for a gapped iron-core reactor and whose manufacturing is simplified.
SOLUTION: A required number of fan-shaped iron cores is prepared by folding-back belt-like magnetic steel sheets in bellows-like shapes by changing fold-back intervals and folding up the folded-back steel sheets. Then this radial iron core is obtained by combining the fan-shaped folded-up iron cores. At the time of folding back the steel sheets, it is desirable to set the fold-back positions of the sheets so that the external forms of the folded-up sheets may become fan shapes when the sheets are folded back in a state where the surfaces of the folded-back portions of the sheets are brought into contact with each other.

摘要： PROBLEM TO BE SOLVED: To more suppress a rise in temperature of a rotor of a rotating electric machine than in a conventional method.
SOLUTION: A cooling medium 31 is flown from holes 15a-15d formed on a rotating shaft 15 to an inner circumferential surface of a rotor holding member 16 having "an outer circumferential surface abutting to the whole inner surface of (a core) of a rotor 12" and "the inner circumferential surface having an abutting region abutting to the outer circumferential surface of a rotating shaft 15 and a non-abutting region with a gap from the outer circumferential surface of the rotating shaft 15". Accordingly, the rotor holding member 16 exchanges heat with (the core) of the rotor 12 while being cooled by the cooling medium 31. Since the outer circumferential surface of the rotor holding member 16 abuts to the whole inner circumferential surface of (the core) of the rotor 12, heat exchange with the rotor 12 is executed in a wider range than in a conventional method.

摘要： PROBLEM TO BE SOLVED: To manufacture a product having improved permeability in the film thickness direction while maintaining existing various characteristics of a sheet as they are, because, in a high permeability sheet formed of a composite material obtained by dispersing a soft magnetic metal foil material into an insulator matrix such as rubber or plastic, there is a problem that in a conventional sheet, the orientation of magnetic powder is random or parallel to a sheet plane, and permeability in the perpendicular direction is low, and, although magnetic powder may be increased to improve permeability in the in-plane direction, the amount of a binder serving as an insulator is decreased accordingly so that the sheet itself exfoliates. SOLUTION: Before or after a process for pressurizing and rolling a composite magnetic member composed of soft magnetic metal foil members and a non-magnetic member interposed between the soft magnetic metal foil members, a magnetic field is applied in the film thickness direction, and a high temperature not lower than a predetermined temperature is set before or after the pressurizing and rolling process to maintain the free movement of soft magnetic metal powder.
