Electromagnetic Braking system

Journal of Magnetism and Magnetic Materials, 2006

A non-contact method, using magnetic drag force principle, was proposed to design the braking systems to improve the shortcomings of the conventional braking systems. The extensive literature detailing all aspects of the magnetic braking is briefly reviewed, however little of this refers specifically to upright magnetic braking system, which is useful for industries. One of the major issues to design upright magnetic system is to find out the magnetic flux. The changing magnetic flux induces eddy currents in the conductor. These currents dissipate energy in the conductor and generate drag force to slow down the motion. Therefore, a finite element model is developed to analyze the phenomena of magnetic flux density when air gap and materials of track are varied. The verification shows the predicted magnetic flux is within acceptable range with the measured value. The results will facilitate the design of magnetic braking systems.

An electromagnetic braking system uses magnetic force to engage the brake, but the power required for braking is transmitted manually. The disc is connected to a shaft and the electromagnet is mounted on the frame .When electricity is applied to the coil a magnetic field is developed across the armature because of the current flowing across the coil and causes armature to get attracted towards the coil. As a result it develops a torque and eventually the vehicle comes to rest. The behavior of two different materials to be used as brake disc which are aluminum & copper was studied. The experiment also aimed to see the effects of increasing the current induced into electromagnet which produce drag force that will slow down the motion. A few graph been presented to show the best material to be used as the brake disc for electromagnetic braking system using eddy current project. The variation in braking time & braking torque with respect to variation in air gap & current was studied & graphs were plotted to show the results.

This paper describes a replacement approach of braking system using magnet. Conventional brakes use friction to apply brake on vehicle. This methodology of braking system is frictionless kind. Electromagnetic braking system provides economical, reliable, and stable braking force. Less use of friction reduces the temperature of the braking system, so there is less wear of braking elements and long life of whole braking system. These brakes offer smart benefits to boost the braking performance of business vehicle. This paper proposes a sway strategy of brake, that is concentrated on the comfort assessment of vehicles. The road conditions are known by the identification parameter, that is obtained once the slip-ratio reaches a particular purpose. The strategy is ready to pick the most swiftness, in line with road conditions still because the comfy feeling of the drivers. The moving speed of the braking pedal is employed to evaluate the driver's non-emergency brake intention. The braking force is distributed on the front shaft and therefore the rear shaft ideally, with the shaft load and therefore the gravity position is taken into thought.

There are various types of conventional braking system such as Drum brake, Disc brake, Hydraulic brake etc. These braking systems produce higher amount of friction which produce heat wear and tear of braking parts. The frictionless magnetic braking system is proposed using eddy current phenomenon. This phenomenon is governed by faraday law of electromagnetic induction and lenz law. Eddy current is created by relative motion between the magnet and metal conductor. The current induce magnetic field in conductor which oppose the actual magnetic field of magnet and result in deceleration of motion.

Most of the braking systems utilize friction forces to transform the kinetic energy of a moving body into heat that is dissipated by the braking pads. The overuse of friction-type braking systems causes the temperature of the braking pads to rise, reducing the effectiveness of the system. An Electromagnetic Braking system uses Magnetic force to engage the brake, but the power required for braking is transmitted manually. The disc is connected to a shaft and the electromagnet is mounted on the frame .When electricity is applied to the coil a magnetic field is developed across the armature. The eddy-current is created by the relative motion between a magnet and a metal (or alloy) conductor. The current induces the reverse magnetic field and results in the deceleration of motion. The proposed mechanism implements this phenomenon in developing a braking system. The potential applications of the braking system can be a decelerating system to increase the safety of an elevator or any guided rail transportation system As a result it develops a torque and eventually the vehicle comes to rest. In this project the advantage of using the electromagnetic braking system in automobile is studied. These brakes can be incorporated in heavy vehicles as an auxiliary brake. The electromagnetic brakes can be used in commercial vehicles by controlling the current supplied to produce the magnetic flux. Making some improvements in the brakes it can be used in automobiles in future. . It also reduces the maintenance of braking system. An advantage of this system is that it can be used on any vehicle with minor modifications to the transmission and electrical systems.

An Electromagnetic Braking framework utilizes magnetic power to connect with the brake. However the plate is associated with a pole and the electromagnet is mounted on the edge .When power is connected to the curl an attractive field is created over the armature in light of the present streaming over the loop and makes armature get pulled in towards the curl. Subsequently it builds up a torque and in the end the vehicle stops. In this task the upside of utilizing the electromagnetic slowing mechanism in car is contemplated.

An Electromagnetic Braking system uses magnetism to interact the brake, but the facility required for braking is transmitted manually. The disc is connected to a shaft and the electromagnet is mounted on the frame. When electricity is applied to the coil a magnetic field is developed across the armature due to the present flowing across the coil and causes armature to urge attracted towards the coil. As a result, it develops a torque and eventually the vehicle involves rest. These brakes are often incorporated in heavy vehicles as an auxiliary brake. The electromagnetic brakes are often utilized in commercial vehicles by controlling the present supplied to supply the magnetic flux. The working rule of this technique is that when the magnetic flux passes through and perpendicular to the rotating wheel the eddy Current flows opposite to the rotating wheel/rotor direction. This eddy current trying to prevent the rotating wheel or rotor. This results in the rotating wheel or rotor comes to rest/ neutral these are totally friction less. Due to this, they are more durable have longer life spangles maintenance is there. These brakes are a superb replacement on the convectional brakes thanks to their many advantages. The reason for implementing this brake in automobiles is to scale back wear in brakes because it friction less. Therefore, there will also be no heat loss. The electromagnetic brakes are much effective than conventional brakes the time taken for application of brakes is also smaller.

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 etc. This paper is an attempt to solve these problems, where a contactless magnetic brake has been developed by using a metals disc which will conduct eddy currents generated by magnets and the same is analyzed by using COMSOL software.
