As vehicle speed increases, a more powerful brake system is required to ensure vehicle safety and its reliability. A contactless eddy current brake (ECB) has been developed to take the superior advantages of fast anti-lock braking ot hte conventional hydraulic brake systems. However, the eCB has a disadvantage that the braking torque decreases in a low speed region. To increase the braking torque, a time-varying mangetic field is used and its analysis is performed. This analysis is new in the sense that the conventional analysis of an eddy current brake was made considering hte magnetic flux density to be time-invariant. Experiemtnal results for a scaled model are presented to have a more reliable result. Lastly, optimization of the ECB for a real model is performed to investigate the feasibility of the ECB for a real vehicle system.
