摘要： The rotary electric machine main body includes: a stator; a rotor that includes a rotating shaft and that is rotatable relative to the stator; and a supporting body that supports the stator and the rotor. The controlling apparatus includes a power circuit portion that is disposed around the rotating shaft, and that converts electric power that is received from the rotary electric machine main body or electric power that is supplied to the rotary electric machine main body between alternating current and direct current. The power circuit portion includes: a power module; and an electric power interconnecting part that includes a conductor that is connected to a terminal of the power module. The electric power interconnecting part is disposed so as to avoid overlapping with a region of the power module when the power circuit portion is viewed in an axial direction of the rotating shaft.

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.
