A Comparative Study between Symmetrical Two-Phase Induction Motor Model Using dq0 Transformation and Model Using Spiral Vector Theory Operating under Unbalanced Voltage

This paper is a comparative study between the classic modeling using dqO transformation (or d-q axis model) and the spiral vector theory applied to study symmetrical two-phase induction machine (STPIM) operating under unbalanced voltage. To compare both types of modeling, simulations were performed to solve differential equations. The comparative graphics are also shown in the paper.
