52" Radiator Cooling Fan
( For WDG-4 / WDP-4 Diesel Electric Locomotive DR120006001 replaceable with EMD** Part No.10632019
) |
|
|
Radiator Cooling Fan 52" are used in the existing
4000 HP EMD Locomotives manufactured by
Indian Railways, where water act as a coolant.
The water temperature is controlled by means of
radiator banks and AC motor driven cooling fans.
Radiator Cooling Fan motors used in existing 4000
HP EMD Locomotives manufactured by Indian
Railways, are of inverted squirrel cage, dual speed,
single winding, 3-phase induction machines and
are an integral part of the cooling fan assembly.
The term "inverted" indicates that these differ
from the conventional squirrel cage motor in the
way that the rotor is located outside of the stator.
All the aluminum castings meet the quality
requirements as per ASTME -155 level 1.
All the machines are tested as per IEEE 112A/ IEC
60349 Pt-II, IS:4722-2001 and IS:4029-1967. |
