What is the formula for calculating no-load current?
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.
