摘要： An automotive dynamoelectric machine that achieves disposing of permanent magnets and thickening of field coil wire by disposing trough portions on yoke portions and disposing magnet holders that hold the permanent magnets so as to span the trough portions to ensure outlet space for field coil lead wires. In the dynamoelectric machine, trough portions are formed on respective portions of yoke portions between circumferentially adjacent claw-shaped magnetic pole portions, a magnet holder is disposed so as to span over a trough portion, and a permanent magnet is held by the magnet holder. A lead wire is led out of a rotor from a field coil so as to pass through a space that is bounded by the trough portion and the magnet holder.

摘要： In a rotary electric machine laminated core, a rotating shaft portion is disposed closer to an outer circumferential surface than an inner circumferential surface of a back yoke portion. A notch portion is disposed on at least one of first and second end portions of the back yoke portion so as to form a gap between a vicinity of the rotating shaft portion of a projecting portion and a recess portion when core segments are arranged in an annular shape or a circular arc shape. The first end portion and the second end portion of the back yoke portion are configured such that a predetermined gap that connects from the outer circumferential side to the inner circumferential side is formed between adjacent projecting portions and recess portions when the core segments are expanded rectilinearly such that magnetic pole tooth portions are parallel to each other.

摘要： A transformer includes a leg iron core including a plurality of magnetic sheets stacked in one direction (Z axis direction), and a coil wound around the leg iron core. A slit is formed in at least a magnetic sheet which faces an inner peripheral surface of the coil in a stacking direction of the plurality of magnetic sheets, of the plurality of magnetic sheets. Since eddy current is divided by the slit, eddy current density can be reduced. By reducing the eddy current density, loss density in an iron core can be reduced. By reducing the loss density in the iron core, loss in the transformer can be reduced.
