摘要： The electric rotating machine is provided with an intermediate plate having a power circuit connection portion that is connected with an outgoing lead drawn out from a power circuit unit and an armature winding connection portion that is connected with the power circuit connection portion and an outgoing lead drawn out from an armature winding. The power circuit connection portion and the armature winding connection portion are arranged at desired positions and outgoing leads from the armature winding of the stator are drawn out in such a way as to fall within a given space, so that intermediate connection lines for connecting windings can be shortened. Accordingly, not only the breakage of an intermediate connection line caused by a vibration can be prevented, but also the switching elements can separately be arranged so as to reduce thermal interference between the switching elements; therefore, the switching elements can effectively be cooled.

摘要： An iron core of a rotating-electric machine and a manufacturing method for the same permit a uniform curvature to be easily obtained over an entire circumference of the iron core. The iron core has laminated magnetic plate strips, a cylindrical core proximal portion, a plurality of teeth projecting in a substantially radial direction from the core proximal portion, and slots for accommodating a winding that are located between the teeth adjacent to each other. The iron core is fabricated by curving both end portions of a substantially hexahedral laminate so that the core proximal portion obtains a predetermined curvature, forming the entire laminate into a cylindrical shape by wrapping it around a cylindrical core member so that distal ends of the teeth project from the core proximal portion, and joining both end portions of the laminate.
