This paper presents a simple method to determine equivalent circuit parameters of double-cage Induction Motors (IM). A new formula to calculate the equivalent circuit parameters of double-cage IM is proposed. The formula is very simple so as to be able to calculate by a calculator but can determine the parameters of outer- and inner-cages bars accurately. In addition it is possible to take magnetic...
This paper presents a practical method to estimate the abnormal field voltage occurrence condition (AFVOC) at asynchronization for synchronous generator (SG) with a brushless excitation having a diode rectifier circuit in the rotational part of the SG. A simulation model to calculate the field transient current at asynchronization to the power bus system is shown. The AFVOC is estimated by simulating...
