This opposing torque is used to brake the automobiles. The development of this invention began when the french company telma, associated with raoul sarazin, developed and marketed several generations of electric brakes based on the functioning principles described above reverdin, 1974. Still other braking methods even transform kinetic energy into different forms, for example by transferring the energy to a rotating flywheel. Traditional electric motors have a tradeoff between high torque and low rotor inertia. A horizontal magnetic force is exerted on the portion of the eddy current that is within the magnetic. Eddy current brake works according to faradays law of electromagnetic induction.

A set of simple experiments is proposed to measure eddy current losses and to relate them to various relevant parameters. Since there is no contact with a brake shoe or drum, there is no mechanical wear. Eddycurrentbrakes seminar report pdf free download as pdf file.

The setup operates like an eddy current brake, a device commonly used in heavy vehicles to dissipate kinetic energy by generating eddy currents. In mountain areas where continuous braking force is needed, for a long time, the eddy current braking is very much useful for working without overheating. However, an eddy current brake cannot provide a holding torque and so may be used in combination with mechanical brakes, for example, on overhead cranes. Mainly this system is purely based on faradays laws of electromagnetic induction and lenzs law. Figure 2 shows the schematic diagram of a simple eddy current brake with only one magnet around it. Eddy current brakes use magnetic fields to convert kinetic energy into electric current in the brake disc, fin, or rail, which is converted into heat.

It uses a two electromagnets which runs by the supply of power from the circuit. Eddy current brakes seminar report pdf seminar topics. According to this law, whenever a conductor cuts magnetic. Eddy current brakes seminar report, ppt, pdf for electrical. This project aims to create a electromagnetic braking system model capable of applying brakes without any friction loss and without losing the energy supplied. However, unlike friction brakes, in which the drag force that stops the moving object is provided by friction between two surfaces pressed together, the drag force in an eddy current brake is an electromagnetic. Eddy current brakes seminar report pdf seminars topics. Pdf final report on electromagnetci braking system. Eddy current brakes use the drag force created by eddy currents as a brake to slow or stop moving objects. Students can download abstract full report in pdf, ppt, doc etc. These seminars also include research papers on many topics and ieee seminars on advanced topics. An eddy current brake, also known as an induction brake, electric brake or electric retarder, is a device used to slow or stop a moving object by dissipating its kinetic energy as heat.
