The Radial Dynamic Braking Resistors complete with Blower Motor set are required to control the speed of the train on a continuous down gradient as well as on level section. 
It consists of a five nos. Non-Fan Tap Radial Grid Resistor and one no. of Fan Tap Radial Grid Resistor mounted on the locomotive. These 6 or 4 Grid Resistor depending upon the requirement those are forced cooled by a D.C. Blower Motor mounted below the radial grid assembly, such that the fresh air is flown through the element assembly. 
Elements of this Assembly : 
. Non-Fan Tap Radial Grid Resistor 
. Fan Tap Radial Grid Resistor 
. D.C. series Blower Motor 
. Blower Fan 
Forced cool convection method is used for cooling of resistor Grid by a D.C. series Blower Motor. Aluminium Alloy die cast axial flow fan is used for cooling of resistor grid driven by D.C. series blower motor. There are various designs of 4 & 6 grid arrangements are designed as per the power requirements.
