The dynamic brake grid cooling fan assemblies consist of a fan powered by a direct current series motor.
Fan and motor assembly consist of five major components:Armature Assembly
Frame and Field Coil Assembly
End Frame and Brush Rigging Assembly
End Frame and Stator Assembly
Fan Rotor Assembly
The grid fans motor is Class H insulated. It is designed for ceiling mounting in the grid hatch assembly and has the fan rotor assembly bolted to the fan mounting hub.
