Resumo
Resumo
This paper proposes a technique to determine the stator resistance of induction machines. The stator resistance is obtained by solving a least squares minimization problem, for which the solution also provides the value of the leakage inductance. The technique exploits the machine behavior with respect to homopolar quantities. It is conceived to be used on-line with the drive strategy without disturbing the angular shaft speed. Experimental results are used to demonstrate the feasibility of the proposed technique.
