- the field circuit unit 24, the power modules 35, and the power interconnection component 36 are attached to the heat sink 37 separate from the rear bracket 8, but Circuitry 24, each power module 35 and power interconnection component 36 may be directly attached.
- a mounting surface perpendicular to the axis of the rotating shaft 12 is formed on the rear bracket 8, and the field circuit unit 24, the power modules 35 and the power interconnection component 36 are common mounting surfaces of the rear bracket 8. Attached to Even in this case, when the power circuit unit 23 is viewed along the axial direction of the rotary shaft 12, the power interconnection component 36 is prevented from overlapping the respective regions of the field circuit unit 24 and the respective power modules 35. It can arrange, and the size of the direction of an axis of rotation electrical machinery 1 can be made small. Further, the function as a heat sink can be added to the rear bracket 8, and the number of parts can be reduced.
