How much energy does a motor convert to heat?
You can calculate the quantity of energy that a motor turns into heat with either one of these equations: Heat energy = ( 1 - efficiency of the motor) x (energy input to the motor) or Heat energy = ( 1 - efficiency of the motor) x (power input to the motor) x (running time)
