APPARATUS FOR INJECTING RESIN INTO LAYERED CORE, METHOD FOR INJECTING RESIN, AND ROTATING ELECTRICAL MACHINE USING SAME METHOD FOR INJECTING RESIN

Document Type and Number:

WIPO Patent Application WO/2014/132682

Kind Code:

A1

Abstract:

It is an object of the present invention to easily inject a resin into voids in a layered core constituting a rotating electrical machine. The invention is provided with a resin supply unit (25) and a resin injecting unit (15). The resin supply unit (25) feeds a resin, and the resin injecting unit (15) injects the resin into an axial direction hole (14) in the layered core. The resin injecting unit (15) includes an injecting tube (16) and an elastic ring (19), the elastic ring being mounted on the injection tube (16). The resin is supplied from the resin supply unit (25) by bringing the elastic ring (19) into tight contact with the inner circumference of the axial direction hole (14), and the resin is injected into a void in the layered core through the axial direction hole (14) in the layered core.
