Description

Stator Rewinding: Charges towards dismantling the motor, threading out the rotor from the stator core pack, stripping out the old winding, rewinding the stator of the above motor using of dual coated class “H” polyamide imide enameled copper wire with class “F” style of insulation and using flexible fibre glass cable, inserting the windings, leading out the end connection, preheating, varnishing with Dr.Beck’s Isonel 31J mixed with thineer 31J, baking in oven, applying finishing varnish to the overhang portions and conducting no load trial run at rated voltage on grounded bed stimulating the site condition and measuring both electrical and mechanical parameters

Stator Core Restacking: Charges towards mounting the stator body in hydraulic press, removing the core pack from stator body with special jigs and fixtures after heating the stator yoke with special heating arrangements, segregating the damaged stator core from core pack, removing the old burnt core plate varnishes by chemical treatment, cleaning, removing the surface kinks, varnishing the stampings in re-varnishing cum conveyor oven to cure the core plate varnish, staggering the core with special jigs and fixtures, locking and repositioning the core pack to the stator body by hydraulic press and finally conducting the flux loop test to ascertain the restacked cover healthiness, cleaning and polishing the slots ready to feeding

Rotor Shaft Replacement Charges towards mounting the rotor in the lathe, removing the core locks, shifting the rotor to hydraulic press, positioning the shaft in hydraulic press using special jigs and fixtures, warming the core pack, removing the old shaft from the core pack, machining EN8 shaft, providing new key way to the core portion, kept the rotor core pack inside the hot chamber, after reaching the core pack to 150OC shift to hydraulic press, inserting new shaft in hydraulic press to ensure proper shrunk-fit, machining the shaft and making the key ways wherever required, including assembling and testing the motor
