Abstract
The behavior of a single-sided linear induction machine (LIM) with short-circuited turns in the primary winding was analyzed using a modified one-dimensional model which considers the end-effects and real winding distribution. Input currents and the motor speed were used as process variables. Due to the end-effects, the negative sequence component of the currents is load-dependent and does not provide a suitable representation of the diagnostic index. The amplitude of the vector ΔĪp = Īp-Īp0 can be used as a diagnostic index since it is correlated with the fault percentage and independently from the load.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
