What will be the impact on motor performance if a LT motor is rewound with changed motor winding data as given below:- Original winding data: total 04 wires = 02 wires of 17 SWG + 02 wires of 16.5 SWG. Changed Winding data: total 03 wires of 15.5 SWG wire size Motor rating: 160KW, 740RPM, 415V, ID FAN application. Normal Running Current = 95% of FL Current.

My question is whether bellow formula is correct to find bus size for 46kA for 0.5 second & what is RT in bellow formula. formula to calculate the size of busbar to withstand the thermal stresses due to currents with duration of 0.2 sec to 5 sec. Sp = RT( I x I x t) / K Where Sp – is the cross sectional area of bus bar in millimeters. I - is the value of AC fault current. t - is the operating time of disconnecting device in seconds. K – is the factor depending on the material of the conductor, insulation and initial and final temperature. Value of ‘k’ for copper is 143.
