EVALUATION OF SUPERMENDUR CUT CORES FOR AN ELECTROMAGNETIC TRANSDUCER
Abstract
The feasibility of improving variable reluctance sonar transducer magnetic core materials by substituting a Supermendur (49% Co - 49% Fe - 2% V) tape wound core for the presently used grainoriented silicon-iron cores was investigated. A 43% improvement in residual induction over the silicon-iron cores was realized by developing a technique to cut Supermendur core materials without degradation. This new core material promises to improve the efficiency of the transducer by providing either a more compact design or an increase in its output. The method consists of electrolytic cutting of a rigid encapsulation of the Supermendur core followed by careful lapping of the degraded surface. (Author)
