State of art automatic winding unit is in house. Slot insulation for fitting of insulation paper in stators. Coil sets are drawn on coil winding machine. Thereafter coil is inserted in stator on coil insertion machine. Coil forming is done on forming machine so as to accommodate another coil set. Thereafter lacing is done on the automatic lacing machine. Stringent tests are done as every rotor is passed through Resistance check, high voltage test up to 1.75 KW on Automatic Sequential Analyzer with Surge Comparison Tests like pulse current and pulse energy.
