要約(英語): Eddy current measurement technology are widely used in instruments such as displacement meters, vibration meters, and non-destructive testing equipment. In this paper, we proposes eddy current speed meter using a rectangular coil and clarifies its speed characteristics using an analytical method. A rectangle has a shape effect not present in a circle and an improvement in characteristics due to the coil system aspect ratio and also improvement in the flux utilization and miniaturization of the sensor can be expected. Therefore, after verifying the validity of the analytical solution through experiments, the speed characteristics are calculated for a case in which the parameters relating to the moving conductor-slab are varied and that in which the coil system aspect ratio is varied. In addition, essential documentation for the optimum design of rectangular coil eddy current speed meter is obtained.
