Title
Unbalanced operation of five-phase induction machines using steady state symmetrical components ℄ Part II - Study of typical cases.
Abstract
In the first part of the paper, a complete model to describe the unbalanced operation of five-phase induction machine is presented. To show the application and validity of this model, in this second part, it is applied to study two typical cases: voltage unbalance and loss of one stator phase. The data used here refer to a five-phase prototype machine of 5.5 kW. Special attention is given to those effects not yet fully addressed in other works, such as additional harmonic induction components in the airgap and high-frequency currents in the rotor windings. These effects can increase the winding and magnetic losses and also change the saturation of the iron parts, thus changing the machine parameters and torque capability. The determination of the additional rotating fields created in the airgap under unbalance helps understand the way pulsating torques and rotor induced currents are produced. The cases studied show that the approach followed can help not only to better understand how the machine works under unbalance, but also provides a powerful tool to design and analyze multiphase machines.
