Induction motor generator flux density
WebThe flux estimator is a full-order, wide speed range stator and rotor flux observer ( Fig. 9.9 ). It contains two models—the open-loop current model, which is supposed to produce an accurate value, especially for low-speed operation, and the adaptive voltage model for wide speed range operation.

Δ Φ Δ t = Δ ( B A cos θ) Δ t = B Δ A Δ t = B v ℓ, 20.34. where we have used the fact that the angle θ between the area vector and the magnetic field is 0°. Once we know the emf, we can find the current by using Ohm’s law.
