Answer Posted / jay
A current carrying conductor rotates only when it is placed in an external rotating magnetic field. Therefore there are two parts in any motor i.e. rotor and stator, one for the purpose of field and other for rotation. although there is a rotating field in a 3 ph transformer the flux and the magnetic field is the same (mutual flux). for the force there should be external magnetic field,current and conductor itself. As there is no external field all the pr and secondary winding do is to induce voltages.

How to select the cable and voltage drop in circuit?
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?
