Embodiment Construction
[0015] In order to solve the problems existing in the traditional vector control method, the present invention proposes a vector control method of an induction motor considering iron loss.
[0016] 1) According to the equivalent circuit of induction motor including iron loss as figure 2 As shown, the derived induction motor vector control has the following expression:
[0017] v ds = R s i ds + dψ ds dt - ω e i qs L ls - ω e i qm L m = R s i ds + dψ ...
