Answer Posted / saeid
The answer is different for different kinds of motors.
However, for all of them there is a similatr reason that
is, there is transient condition during statr up that cause
thier winding impedance become different than runing time.
So because transient impedance is much less than staedy
stat impedance, the starting current is much higher than
runing current.
Even it happen for DC motor.
As I said in the begining, there are some other reasons
that make starting current different for DC(12 to 20times),
induction(6 to 10times) and synchronuose (12 to 20times),
motors.
