star connection for a 3 phase induction motor gives reduced starting current.but 1.732 times the rated current during run up period if the motor was designed to run on delta. Why can't we design the motors to run on star connection instead. It will remove the starting arrangement required making the construction an operation much simpler.

Answer / suresh jangid
Because of the power generated I delta starters for an induction motors is twice dat v cn achieve in star starters hence v opt for a star delta starters so that v cn tk advantage of both things simultaneously. Reducing the starting current as well attaining maximum power at rated speed oc motors.
