Answer Posted / sunil kumar sinha
^.^ KV motors are generally star connected because
insulation of winding of motor and interturn insulation is
much less because voltage across each turn in star winding
is much less (root three times) than the windings of delta
connections.
If 6.6 KV delta motor is to be manufactured the insulation
level will be much higher between turns as well as winding
as it will experience voltage level of 11 KV STAR MOTOR.
tHE SIZE OF MOTOR WILL BE BIGGER BECAUSE OF HIGH INSULATION
THICKNESS IN THE WINDING AND IT WILL BE COSTLY ALSO.
