why rotor starter is unsuitable for squirrel cage Rotor?

Answer:
◼️hii mate◼️
Explanation:
in squrielcage induction motor the rotor bars are short
circuited. there is no provision of including resistances on rotor side but in slip induction motor, the rotor bars are connected to slip rings for providing and an external resistances thats why tha rotor resistance starter can be used in only slip ring induction motor.

Answer:
A synchronous motor may have a squirrel-cage winding embedded in its rotor, used to increase the motor starting torque and so decrease the time to accelerate to synchronous speed. The squirrel cage winding of a synchronous machine will generally be smaller than for an induction machine of similar rating. When the rotor is turning at the same speed as the stator's revolving magnetic field, no current is induced into the squirrel-cage windings and the windings will have no further effect on the operation of the synchronous motor at steady-state.
