| Popis: | In induction machines, the knowledge of more than the fundamental wave values of voltage and current can be used for higher efficiency, reduction of costs and size, and on-line condition monitoring. By evaluating the transient electrical behavior, the machine acts like an embedded sensor itself. While the transient electrical behavior is heavily influenced by the depth of penetration of the flux into the rotor, it is strongly dependable on the shielding effects taking place in the machine. For this contribution the specially attached shielding to the rotor and its influence on the detected behavior is discussed. It is shown, that a huge influence on the transient behavior can be found, while the change of fundamental behavior is negligible. |
