International Journal of Engineering Research and, 2017

An Electromagnetic Braking system utilizes Magnetic drive to connect with the brake, however the power required for braking is transmitted physically. The disc is associated with a shaft and the electromagnet is mounted on the edge .When power is connected to the curl(coil) a magnetic field is produced over the armature as a result of the present streaming over the loop and makes armature get pulled in towards the coil. Thus it builds up a torque and in the end the vehicle stops. In this venture the upside of utilizing the electromagnetic stopping mechanism in car is considered. These brakes can be consolidated in substantial vehicles as an assistant brake. The electromagnetic brakes can be utilized as a part of business vehicles by controlling the current provided to deliver the attractive flux. Making a few enhancements in the brakes it can be utilized as a part of automobiles in future.

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.

The design of an electromagnetic disc brake requires a multidisciplinary approach. Its performance is an outcome of usage of concepts from various fields' viz. mechanical, electrical, magnetic and material engineering. This paper describes a new type of electromagnetic disc brake for retarding the motion of a vehicle. In this study, a comprehensive design procedure for electromagnetic disc brake is presented to ensure maximum efficiency along with effective braking. Varied magnetic materials are discussed in terms of minimizing the cost while meeting electromagnetic performance characteristics. An analytical model is developed to optimize braking effort with combination of input current and voltage using sensors and voltage regulator, wear and tear of brakes, maintenance. Calibration between spring expansion (output) and source voltage (input) is derived for prompt operation of the brakes. Also, structural analysis of nodal forces on the cross-structure and brake disc is also carried out to ensure reliability. The analytical results so obtained are within the acceptable range for braking.

The behaviour of electromagnetic braking using eddy current was studied. Started with preliminary study investigating 3 different materials of aluminium, copper and zinc to choose the best material as brake disc. It also looks on effects of increasing current induced into electromagnet. Aluminium performs better copper and zinc, and then the study continues using two different series of aluminium which are Al6061 and Al7075. A few parameters been varied such as air-gap, brake disc thickness, number of electromagnet turns and voltage supplied to DC motor. For the purpose of recording speed (rpm) and time (s), an optical tachometer connected to PULSE analyzer been used. Graphs presented to show the behaviour and reaction of parameters involved, including the calculation of braking torque that been generated using previous study equation. From this study, it can be concluded that Al6061 have greater performance than Al7075 as the brake disc material. It also founded that the thicker the disc, small air-gap, large number of electromagnet turns and increasing the current induced will increase the performance of this electromagnetic braking. All parameters that been studied show significant effects to be considered in developing electromagnetic braking to replace the conventional braking system.

Two different series of Aluminium which are Al6061 and Al7075 has been studied as the brake disc material for this electromagnetic braking system using eddy current. Both series been studied experimentally by varying a few parameters such as current induced to the electromagnet, air-gap, brake disc thickness, number of turns and voltage supplied for the DC motor. PULSE analyzer been used to capture the speed (rpm) and time (s). This paper also addressed the calculation for the braking torque that been generated during the process by using previous study equation. From this research, it can be concluded that thicker disc performs better with electromagnetic braking and smaller air-gap produced high braking torque in order to stop the disc rotation. Besides that Al6061 have greater performance than Al7075 for electromagnetic braking purposes as the brake disc material.

Many costs are unlikely to be rejected in transportation engineering, such as delivery and accuracy over ambiguity. The electromagnetic braking system reduces or stops the rotation speed of the rotating disc or wheels using magnetic force. The benefits and limitations of caliper pressure and heat dissipation come with the concept of electromagnetic braking. Magnetic force is used to transport components of the brake device in the braking system. When a magnetic field is started within a revolving disc, the device introduces the signal that the opposite side produces a eddy current or rotation of the disc brake. Braking discs, solenoid, circuit board, and battery power are all components of the electromagnetic brake disc. The braking device is an ancient example of maximizing braking efficiency while minimizing losses. The contrast between electromagnetic braking machines with traditional exhaust brake devices is the focus of this paper. The Electromagnetic machine is now focusing on minimizing tool loss in order to increase tool safety. The main objective of the study is to examine the benefits of both arrangements while also highlighting their uncertainty.
