ABSTRACT:
A method of recovering resources in a resin-molded electrical rotating device (1,2) in which electromagnetic members (1a,1b,2a) are molded with resin molding (1c,2c) with fine voids so as to be integrally made into a solid body, and a resin for molding of the rotating device (1,2). The method has the steps of disintegrating the resin molding (1c,2c) by chemically decomposing and/or eluting so as to remove the resin molding (1c,2c) from the electromagnetic members (1a,1b,2a) and separating and recovering at least metal components in the electromagnetic members (1a,1b,2a) as the resources.
