A rotating electric machine to which the present invention is applied includes: a plurality of coils provided in a stator for respective phases; a plurality of bus bars having elasticity, which are provided for the respective phases and connected to the plurality of coils; and a holder including a plurality of insertion portions each having a groove shape formed to deform each of the plurality of bus bars.

Rotating electric machine

In order to achieve the above object, according to one aspect of the present invention, there is provided a magnetoelectric generator including: a flywheel rotating around an axis of rotation; a plurality of magnets disposed on an inner peripheral surface of the flywheel and rotating together with the flywheel; a stator core disposed radially inside the magnets, the stator core being constituted by stacking a plurality of thin steel sheets and having: an annulus portion; and a plurality of teeth projecting radially outward from the annulus portion; and a generating coil configured by winding conducting wire onto the teeth, wherein: a coolant aperture through which a coolant passes is formed on the annulus portion so as to penetrate through the thin steel sheets in a direction of lamination.

Magnetoelectric generator

A stator core includes: a laminated body in which a plurality of intermediate plates that have dowels are laminated so as to be integrated by dowel crimping between layers; and a pair of end plates that are disposed so as to be positioned on opposite sides of two end surfaces of the laminated body, and a receiving aperture that extends parallel to an axis of rotation is formed on the laminated body, a bent portion is disposed on the end plates, and the end plates are joined to the laminated body by engaging the bent portion in the receiving aperture.

A conductive member includes a strip conductive portionand an arm portionintegral with the strip conductive portionand extending from a side end portionof the strip conductive portionto be almost parallel in a longitudinal direction, the arm portion being bent in a direction of plate thickness for the strip conductive portion
