Dynamic and steady state performance of higher phase order (HPO) squirrel cage induction machine

Abstract

In this paper, the performance behaviour of a symmetrical higher phase order (hpo) squirrel-cage induction machine is carried out. The machine stator winding is connected to a balanced phase supply and the machine performance characteristics observed during normal operation in loaded and unloaded conditions. The hpo squirrel-cage induction machine is investigated using the generalised theory method (dq0) and the finite element method (FEM). The steady state and the dynamic results characterising machine performance are generated. Tests are conducted on a 1.5 kW experimental machine to validate the results obtained from the theoretical studies. The results of the two methods used are compared with the experimental. It is shown that the generalised theory method have a higher performance as compared to finite element analysis (FEA) during the steady state analysis.
