Determining the Braking Resistor

1) The resistance value must be between the minimum resistance calculated in step 4 and the maximum

resistance calculated in step 5.

2) The power rating of the resistor must be equal to or greater than the average power rating calculated in step

6.

3) The Braking Resistor must also be able to handle the peak power generated during deceleration. One

option is to choose a resistor whose power rating is equal to the peak power calculated in step 3 instead of
the average power calculated in step 6. The other option is to find the peak power rating for the resistor.
Braking resistor manufacturers have two methods of defining the peak power a resistor can tolerate.



One method is to define peak power as a percentage of average power.



The other method is to define the energy the resistor can absorb, typically in joules. This calcula-
tion is J = (P

b

/2 X T

d

), where J is the energy in joules, P

b

is the peak power during deceleration,

and T

d

is the time to decelerate.
