The eddy current brake has the advantage of being able to take a high current density compared to the other application because this brake is used for applying brakes to the rolling stock for a shorter amount of time. Also, this braking system has the merit of being able to take a high current density at low speed rather than at high speed, because the heat generated by the low speed operation is less than that of the high speed operation. This paper also presents a method of improving the output torque of the eddy current brake at low speed operation through a change of the winding as well as the basic design.

  • Brakes Andrelated Systems
    BRAKES ALL MODELS Air Brake Modifications Certification Procedures For DOT FMVSS-121 The Federal Department of Transportation's Motor Vehicle Safety Standard 121 required that virtually all trucks equipped with air brakes and manufactured on or after March 1, 1975 must comply with a comprehensive set of design and performance parameters concerning the air brakes and related systems. Of the many requirements of FMVSS 121, two are of primary concern between the truck manufacturer and the body and allied equipment manufacturer. The first concern is the center of gravity location on a truck used for compliance testing and the second involves the tubing and air flow design of the brake system. Cautions - FMVSS-121 Air Brake System Modifications CAUTION: If wheelbase alterations are made to International vehicles with FMVSS-121 brakes: • DO NOT make alterations to air lines with hose, piping or fittings of sizes other than those currently in use on the truck. • DO NOT allow sharp bends or other constrictions in hosing. • DO NOT exceed the minimum or maximum wheelbase available from the factory for that model after lengthening or shortening the wheelbase. For wheelbases longer or shorter than those available from the factory, International will provide verbal opinion (through contacting your local International dealer). International will be available to provide certification testing and documentation of compliance or non-compliance with FMVSS-121 for the specific situation at an additional cost. dy Builder Diagrams (CT-471) 2010 October, CAUTION: Air reservoirs may be relocated providing these guidelines are followed: • DO NOT make alterations to air lines with hose, piping or fittings of sizes other than those currently in use on the truck.

Professor, Department of Mechanical Engineering, Francis Xavier Engineering College, Tirunelveli, Tamil Nadu, India2 ABSTRACT: This project is a new technology in braking system. Electromagnetic braking system is used in light motor and heavy motor vehicle like buses, truck, etc. An Electromagnetic Braking system uses Magnetic force to engage the brake, but the power required for braking is transmitted manually. The electromagnetic braking systems are also called electro-mechanical brake .In Future we can use this braking system to avoid the accidents. An electromagnetic braking system uses a magnetic force to apply brake. The power source used in the electromagnetic break is electric current. The electric power applied to the magnetic coil developes the magnetic field in armature coil and attracts the electromagnet aluminum disc. Applying brake to stop the vehicle. I. INTRODUCTION A brake is a device which inhibits motion. Its opposite component is a clutch. Most commonly brakes use friction to convert kinetic energy into heat, though other methods of energy conversion may be employed. For example regenerative braking converts much of the energy to electrical energy, which may be stored for later use.

  • Design and Development on Electro Magnetic and Automatic Breaking System
    DESIGN AND DEVELOPMENT ON ELECTRO MAGNETIC AND AUTOMATIC BREAKING SYSTEM GUIDED BY :- PROF. MANOJ P . RAJPARA PREPARED BY: GROUP NO:-27 RAJPUT VIPUL 11ME64 PARAJAPATI NIKUL 12ME02 MODI SAGAR 12ME17 DARJI MILAN 12 ME18 CONTENT Introduction Project Principal Literature Review Types of brake Component Component design Construction Future Scope Advantage Disadvantage Application Work Planning Reference INTRODUCTION In this project we have designed and establishment and Electromagnetic disk braking system so as to have a future alternative to traditional breaking systems. Electromagnetic disk braking system slows an objects by creating an eddy current through electromagnetic induction which create resistance. When electromagnetic are used, control of the breaking action is made possible by varying the strength of the magnetic field of the electromagnets creates eddy currents in the discs. These eddy currents generate an opposing magnetic field (Lenz's law), which then resists the rotation of the discs, providing braking force. The net result is to convert the motion of the rotors into heat in the rotors. Electro magnetic and auto breaking system designed to develop a new system that can solve this problem where drivers may not brake manually but the vehicles can stop automatically due to obstacles. This project is about a system that can control braking system for safety. Using ultrasonic as a ranging sensor, its function based on ultrasonic wave. After transmit by transmitter, the wave can reflect when obstacle detected and receive by receiver. The main target for this project is, car cans automatically braking due to obstacles when the sensor senses the obstacles. The braking circuit function is to brake the car automatically after received signal from the sensor.
