I could find a relation between rotor Cu loss and slip.

Rotor Cu loss = Slip * Rotor input

But there is no relation between no load losses and slip. No-load loss depends on voltage.

It does not depend on core loss componenet .

As slip=(Ns-Nr)/Ns

from the relation above its only depend on synchronous speed Ns , rotor speed Nr and shaft torque of motor

 

The answer is NO

Slip= (Ns-Nr)/Nr

Ns= Synchronous Speed

Nr= Rotor Speed

(Slip depends on Synchronous and Rotor Speed, not on core loss components)
