1 Repair to 100 HP 3 phase induction motor of pumping unit no.01 installed at LIS Kotgarhi H/L. The job involves dismantling the motor by unfastening the foundation nuts and bolts and also decoupling from the pump and disconnecting the electrical connections from the main supply. Shifting of the motor to workshop by mechanical transport. Then complete dismantling of the motor involves extraction of rotor from stator followed by cleaning of stator and rotor using compressed air, organic solvent, CCL4 etc. to remove the dust particles /silt etc. Extraction of burnt winding from the stator, cleaning of stator with petrol. P/F of new winding wire of suitable gauge & size in the stator, varnishing the stator winding with superior quality of varnish. Drying the stator winding with hot air circulation process. Assembling of the motor. Shifting the motor back to LIS. Refitting the motor at its installed position and coupling with pump, making of electrical connections, alignment with pump, testing of motor on full load. Complete job includes the cost of material, labour charges, hiring charges of tools & tackles, transportation charges. 01 Complete Job 2 Repair to 90 HP 3 phase induction motor of pumping unit no.01 installed at LIS Aizal Malal .
