Homework Help: Electromagnetic Brake system

  1. Jun 16, 2011 #1
    1. The problem statement, all variables and given/known data

    Design and Perform calculation for an Electromagnetic Brake system of a truck having 3 Axils assuming that each axil carries equal load. The truck is carrying a load of 30000 Kg and the weight of truck is 6000 Kg and moving with 100km/h speed before the brake is applied.
    calculate.
    1) Braking Torque
    2) Magnetic Filed required to reduce the vehicle speed upto 20 km/h
    3) current required
    4) suitable material
    5) design the brake

    2. Relevant equations

    how to calculate current required

    3. The attempt at a solution

    I have calculated Braking torque and magnetic field. which is shared on following links.
    The torque I got , is too much, i think.. please tell me if I am wrong
