Application of Electromagnetic Braking Torque and Different Braking Modes Programmed with ATmega328p Microcontroller in Electromagnetic Braking System

Electromagnetic braking system uses magnetic force in order to stop the vehicle. In the present design, a disc with requisite number of solenoids has been arranged for achieving the purpose. While trying to stop the vehicle, the pilot needs to turn on the brake switch to supply electric power. Thereby a magnetic field will be developed on the ambience of the solenoids which will prohibit the rotation of the disc and eventually the vehicle will come to a halt. The wheel torque is evaluated from various experimental data and in this paper a comparison is made between the braking torque and wheel torque. Realistic calculation in this paper reveals that value of braking torque using electromagnetic brake can be made greater than the torque of the wheel, which is actually needed to stop any vehicle. Different braking modes have been achieved with Arduino, ATmega328p microcontroller based programming using ultrasonic sensors. This paper aims to find a faster, efficient and safe way of braking with almost no maintenance cost and least possibility of brake failure.
