Abstract

The principle operation of eddy current brakes is based on relative motion of a rigid conductive core in a magnetic field. In spite of simple structure, eddy current brakes employ complicated mathematical relations in operation. In the past, many researchers have investigated the problems of eddy current brakes. But most of them only considered distribution of induced currents and the resultant magnetic field intensity and ignore the skin effect whereas skin effect plays a significant role in torque-speed characteristic of eddy current brakes. In this paper we have studied the operation of cylindrical eddy current brake emphasizing skin effect theoretically and empirically.
