Consideration of Basic Characteristics Study on Eddy Current Brakes with Double Rotor Type

Abstract

　The authors have been studying non-contact brakes using eddy current brake as the next generation for aircraft. This paper deals with basic characteristics of double rotor type eddy current brakes by measurement of experimental machine and analysis. As a result, the measured braking torque value of the experimental machine was smaller than the value derived from analysis. And the analytical values do not take thermal characteristics into account, so there is a difference with the measured values from an experimental machine that generates heat. By considering the effect of energy stored in the coil, it was found that the energy stored in coil smaller than the heat generation one.
