A name Plate of SlipRing Motor Present that the Rotor Connect as Delta connection so How the Starter Work in this case, and short circuit contactor?

Slipring motor's ROTOR is always STAR connected . Mistake in NAMEPLATE

At the slip ring type of motor for the phase rotor,using resistance set,for the decrease starting current,switching for the rotor resistance occur by relay protection that smoothly reduce resistance when motor increase maximum RPM, if we don't have protection scheme, we can connect direct to the contactror,and starting current will be high

hy ressistence rooter connection  transfer low ressistence start the starter
