Title:
ROTARY ELECTRIC MACHINE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2019/220660
Kind Code:
A1
Abstract:
This rotary electric machine is provided with an armature and a rotor, wherein the rotor has: a rotor core which has a plurality of slots open radially outward and extending in the axial direction thereof; field windings accommodated in the respective slots; a plurality of split wedges which are accommodated in the opening sides of the respective slots so as to be arranged in the axial direction, and which fixedly hold the field windings inside the slots; and holding rings attached to both axial end sections of the rotor core . The plurality of split wedges each include a composite wedge, and the composite wedge is provided with a main body part that holds the field winding and a conductive body which is held by the main body part and through which an overcurrent flows, wherein the main body part is manufactured by using a non-magnetic material having a higher strength than the conductive body, and the conductive body is manufactured by using a metal having a higher conductivity than the main body part.
