ABSTRACT:
A shield band, made from grain-oriented silicon metal, is wrapped about a case of a motor to reduce electromagnetic emissions. The case is protected by a strip of tape adhered to an outer surface of the case. The shield band is made by pressing a strip of metal against a strip of tape with an adhesive agent between them. The resulting strip is cut to length and curled around a roller to form a band which conforms to the outer perimeter of the small D.C. motor. A plate bridges the facing ends of the shield band.
