motor if any difficulty arise the contractor has to attend it with out any extra cost.
5) Motor space heater wiring should be replaced with new heat resistive wire of good quality at every
work of rewinding and heater to be tested at 230 volt A.C .supply.

passing payment.
10) Complete restaggering / recagging of rotor core:-
After Removing the shorting ring of rotor at both end and the rotor bars, unlock the locking device of
rotor core. Remove the lamination leaves from the rotor;cleaning of burnt varnish, oil, grease, dirt from
the lamination leave then varnishing them with core plate varnish of Dr.back & co. make. Backing, drying
the leaves, retargeting the lamination across the periphery by distributing damaged core leaves in such a
way that uniform flux density may be produced as developed in healthy rotor core. Pressing the core
lamination with required pressure so that radial air vent duct may not be deformed. Locking the Core on
shaft of rotor as per original one. Remove the burrs in slot portion by smooth filing. Apply anti corrosive
varnish and final coat of Bactol red by spraying.
The repair rotor core may be tested for full flux loop test and confirm that there should not be any hot spot
