A method of iron loss and magnetising flux saturation modelling in stationary frame reference of single and two-phase induction machines

This paper proposes an equivalent circuit for the single and two-phase induction machines including simultaneously, but as independent phenomena, the iron loss and the main flux saturation. This model permits an improvement in operation of vector-controlled single and two-phase induction machines. The vector control structure suitable for the unsymmetrical two-phase induction machine can be either rotor or stator flux oriented control. The model can be implemented for simulations by using either experimentally determined parameters or FEM calculated parameters. The stator field oriented system can be readily implemented on the same DSP board with the rotor field control version, as the same parameters are used. It is expected that the stator flux control should be more suitable for low speed applications, while the rotor flux control system is useful for high-speed applications
