The design of an electromagnetic disc brake requires a multidisciplinary approach. Its performance is an outcome of usage of concepts from various fields viz. mechanical, electrical, magnetic and material engineering. This paper describes a new type of electromagnetic disc brake for retarding the motion of a vehicle. In this study, a comprehensive design procedure for electromagnetic disc brake is presented to ensure maximum efficiency along with effective braking. Varied magnetic materials are discussed in terms of minimizing the cost while meeting electromagnetic performance characteristics. An analytical model is developed to optimize braking effort with combination of input current and voltage using sensors and voltage regulator, wear and tear of brakes, maintenance. Calibration between spring expansion(output) and source voltage(input) is derived for prompt operation of the brakes. Also, structural analysis of nodal forces on the cross-structure and brake disc is also carried out to ensure reliability. The analytical results so obtained are within the acceptable range for braking.
