Induction motor will be stable when load Torque (${\mathit{T}}_1$ ) increases then speed will reduce i.e. motor will deaccelerate till motor Torque is equal to load torque. If load Torque (${\mathit{T}}_1$ ) decreases then speed will increase i.e. motor will accelerate till motor Torque is equal to load Torque. So ‘ω’ is state region.
