DEMPER WINDING IS PROVIDE TO TOP OF THE WINDING & ITS
MATERIAL CHARACTERISTICS- IT IS PROVIDE A HIGH RESTIVITY &
HENCE AT STARTING MOST OF FLUX LINKING TO THE DEMPER WDG. &
DUE TO THIS ,IT IS PROVIDE A HIGH RESISTANCE TO THE WINDING
AT STARITNG & LIMIT THE CURRENT AT STARTING , HENCE HIGH
TORQUE WILL BE PODUCE AT STARTING

T= E2/R2+SX2
