“…Permament magnets based rotors could instead have the saliency in the opposite direction (L d < L q ), due to the low permeability of the permanent magnets. But the saliency is dependent on the rotor design, and modifications to the angular direction of the magnetic flux paths in the rotor could instead give an angular displaced or reverse saliency [7][8][9][10].…”

“…The easier magnetization along the direction of the excitation flux gives higher inductance in the d-direction and lower inductance in the q-direction. But there are also alternative designs with reverse saliency such that the easy direction instead is along the q-direction, acting in a manner opposite to that of classical saliency, with a negative contribution of the reluctance torque for low load angles [7][8][9][10].…”

This paper describes a simplified one-phase equivalent circuit model of three-phase salient pole synchronous machines and synchronous reluctance machines. The model represents the pole saliency as a susceptance, with a magnitude based on the pole saliency and a phase angle based on twice the load angle. The reluctance torque itself is then modeled equivalent to a conductance. The model is made as an extension to Norton equivalents, where the internal inductance is connected as a shunt. This approach shares similarities to the magnetization shunt branch in circuit models of transformers and induction motors. The model is derived using the rotating dq-frame, using Park transform and two-reaction theory. The model is then rewritten to better fit one-phase equivalent circuit models, with the terminal voltage as the angular reference. The resulting two-pole model can then more easily be combined with basic circuit theory, thereby synthesizing dq-theory and phasor circuit models.
