Torque required to run a roller

  1. Mar 18, 2010 #1
    Hallo.

    I have a problem

    i want to know why my Invertor is burn.

    the Object speed 0.5 m/s in 3 seconds then constant 0.5 m/s
    that mean acceleration = 0.167

    for Object

    use F=ma = 5000*.167= 835 N
    and Torque= F*r = 835 * 0.20 = 167 N.m

    for Motor

    Omega W=n * 2pi/60 = 2990*2*pi/60 = 313

    Torque = P / W = 2600 Watt/313 = 8.31 N.m

    ration of wheel = 50:1 then 8.31*50 = 415 N.m

    My Motor have Torque = 415 but load only 167 N.m. Why my invertor is broken ?

    or i have miss calculate
