SINCE BOTH FIELD AND ARMATURE ARE CONNECTED IN SERIES THE
TORQUE EQUATION IS T=KI2. (TORQUE PROPORTIONAL TO SQUARE OF
CURRENT).
ALSO NOTE THAT FROM THE CHARACTERISTIC IT IS THAT AS SPEED
INCREASES THE TORQUE DECREASES AND VICE VERSA.
THEREFORE THE TORQUE IS HIGH ONLY AT LOW SPEED.

Dear All we are having a problem in G120 BOP showing alarm A0503, F0052, F0060 we can not remove fault alarm ,Please any body help us. kowsar
We have drive feeding an output contactor for a 5000 hp motor @ 5kV application. The motor FLA is 629amps x 1.25% service factor = 786.25 amps The cable that we current have in place between the drive and the output contactor is 350kcmil- MV-105 (parallel cables). Per the NEC table 310.60 (C) (69). This show the cable ampacity is at 615 amps per cable for a rating of 1230 amps. We have derated the cable for the cable tray and the multiple cables application and our calculations show that after the correction factor factor we are at 922amps. 1230 amps x .75% correction factor factor = 922.5 amps. The customer is driving us to then use another safety factor of .25% off of the already derated cable. Can you please provide a longhand calculation for your solution on this application?
