PROBLEM TO BE SOLVED: To provide a laminated can for ammonia canned motors wherein ingress into a stator space is prevented by the inner surface of a first layer which constitutes the can inner cylinder in contact with ammonia without limiting the resin for use in the can for ammonia resistance of an ammonia canned motor to fluorocarbon resins, by using as a strong binder a resin which is resistant to a heat of up to approximately 150°C, excellent in adhesion, and easy to process. SOLUTION: The first wrapping layer 20 is formed of ammonia-resistant, ultrathin, soft magnetic metal foil which is fit to a bobbin and whose inside surface is bonded thereto. A second wrapping layer 21 of high-tensile woven fabric is formed on the periphery thereof, and heat-resistant, highly adhesive resin is applied thereto. A spiral, high-permeability, small-gage wire 23 is tightly wound therearound. Further, a wrapping layer 22 of high-tensile woven fabric is formed on the surface thereof. Resin is applied to the front face and the back face of these laminated portions, and is integrated to constitute a laminated can 16. COPYRIGHT: (C)2005,JPO&NCIPI
