    HI guys,

    I am currently working on my Three Phase Induction motor topic. I am request to prove the relationship between RPM vs VL. when the VL is increase, the RPM will be increase too. I am using below equations to prove this task. Please correct me if i am wrong.

    S=(ns-n)/ns
    While s=slip, ns=synchronous speed, n=motor speed
    *when n is increase, s will be decrese

    s=kTR/E[square]
    k=constant depends on motor design,T=torgue,R=rotor resistance,E=stator voltage
    *when S decrease, E will increase
