International Journal of Advanced Research in Electronics, Communication & Instrumentation Engineering and Development Volume: 3 Issue: 2 Apr,2017,ISSN_NO: 2347 -7210 FRICTIONLESS BRAKING SYSTEM USING EDDY CURRENT Sandeep.V 1 , Avinash A.B 2 , Rupan Raj. J 3 Professor, Dr.Manikandan, M.E., Ph.d., Electronics and Instrumentation Engineering, Panimalar Engineering college, India 1 . Asst.Professor, Mrs.S.Lakshmi, M.E., Dept.of Electronics and Instrumentation Engineering, Panimalar Engineering College, India 2. . ABSTRACT Majority of braking system work on the principle of dissipation of kinetic energy to heat energy.This method has its own drawbacks and must be replaced with more reliable braking system that is quick in response,doesn’t heat and also maintanenece free.In t his project,a frictionless braking system is proposed using eddy current phenomenon.This phenomenon is governed by faraday’s law of electromagnetic induction and Lenz law.Eddy cureent is created by the relative motion between a magnet and a metal(or alloy) conductor.The current induces magnetic fieldsin the conductor which opposes the actual magnetic field of the magnet and results in the decceleration of motion (Lenz law).The constant magnetic field is the simplest and easiest design to implement.The mechanism implements this phenomenon in developing a braking system.This braking system is frictionless,hence it’s advantageous over conventional friction brakes in terms of performance and maintanence.The proposed system is implemented in rear wheel of vehicles. Keywords Aluminum Disc;Neodymium Magnet; Speed sensor. . 1, INTRODUCTION The goal of this project is to use the physics of eddy current.We have created an eddy current brake which uses the same eddy current effect as an eddy current motor but is simpler to build.We hope to learn the effect of stor spacing,magnet size and shape,number of magnets,magnet radius,and phase angle have on braking force.Thus information will be used by another team to create an eddy current motor. An eddy current brake like a conventional friction brake is device used to slow or stop a moving device by dissipating it’s kinetic energy as heat.However,unlike Drum and Disc brakes,in which the drag force are used to stop the moving object provided between two surfaces pressed together by friction,the circular electric current brake called eddy current brake whose drag force is an electromagnetic force between a magnet and a nearby conductive object in relative motion,because of the eddy currents induced in the conductor through electromagnetic induction.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
