Answer / vinod
When three phase voltage is applyed across the stator a
flux with syn speed will be rotated inside the stator, as
the rotar is stationatory max, voltage will be induced and
high startin current is drawn.

Answer / jayaram
iniatially the motor don't have any backemf so motor draw
high current at the starting stage. whenever motor is
started it generates backemf so motor takes normal load

Answer / sanjana singh
in starting motor resistance is negligible.so according to formula-
I=v/Ra ( Ra can be neglected)
then I=V ( Starting current is equal to supply voltage)
so to start motor starter is used. it add resistance in series of motor by this starting current limit to safe value & motor start safely...
