what is the function of a starter in a motor?
explain RLC circuit.
Answer Posted / ashokreddy r
Function of starter is to limit the starting current and
make the motor start in a desired and safe way.
For dc motor we can go for resistance starters(3-point,4-
point)
For 3phase induction motors we can go for
DOL STARTING ,STAR DELTA STARTING,RESISTANCE STARTING,AUTO
T\F STARTING.

I have a small system with two motors that are running on 380 vac, 60 hz. These motors are expensive and I usally get them from Brazil. I am adding another motor to the system, but I want to purchase a 480 vac, 60 hz motor to use. It will be on a VFD that is rated fro 380 thru 480. Is this posible and will I have to use a larger motor and derate it?
