Abstract

Eddy currents are generated when a moving conductor is exposed to a stationary magnetic field, or vice-versa. These currents create their own magnetic field, causing a repulsive force between the magnetic material and the conductor. Using this concept, a magnetic brake system can be established by the permanent magnets and a conductive material. In this paper, the eddy current effects on a magnetic brake system which consists of 2 pairs of magnets and a conductor are investigated by using a electromagnetic software, and the results of simulations are compared with experiments. It can be concluded how the arrangement of magnets effects on the dynamic characteristics of the eddy current brake system.
