Contactless Eddy Braking System


Abstract: Majority of braking systems work on the principle of dissipation of kinetic energy to heat energy. This method has its own drawbacks and must be replaced with amore reliable braking system that is quick in response, doesnít heat up and is maintenance free. In this project the design an eddy current braking system and optimization for various operational parameters has been done.These parameters have been previously iterated in cited projects and papers and also in the simulation models and are to be cross-checked with the experimental setup.In the operation of any machinery the most primary safety system is the braking system. The most basic designs of the braking system involve the conversion of kinetic energy to heat energy by friction. This is accomplished by friction between two rubbing surfaces. These brakes pose several problems i.e. significant wear, fading, complex and slow actuation, lack of fail-safe features, increased fuel consumption due to power assistance, and requirement for anti-lock controls. To solve these problems, a contactless magnetic brake has been developed. This concept includes a metals disk which will conduct eddy currents generated by magnets. This brake is wear-free, less-sensitive to temperature than friction brakes, has fast and simple actuation, and hasa reduced sensitivity to wheel lock. This is achieved by the generation of braking torque by a magnetic field across a moving conductor which creates a perpendicular magnetic field by induced eddy currents. Contactless brakes can be applied to any machinery like automobiles, locomotives, roller coasters, hydraulic and turbo machinery, machine tools, elevators, etc. The wide range applicability of these brakes strongly imply the effectiveness and ease of operation. The braking force can be adjusted to control higher torque loads by varying the coil turns or by increasing the voltage.Modelling of designed experimental setup is done in Autodesk Inventor and simulation analysis is done in COMSOLMultiphysics software. By Schieberís equation, it can be said that withincrease in air gap and disc thickness, the torque generated by the electromagnets is decreased. This relation can be verified by noting the stoppage time after varying the air gap. As per the model the stoppage time must reduce with increase in air gap
