This electro-mechanical converter converts the pase currents and voltages to space phasors in the rotor fixed frame. Here Kirchhoff’s voltage law for d- and q-axis are formulated, included the induced voltage due to the permanent magnets. Additionally, a relationship between zero component voltage and current using the zero-component inductance L0 is established. Last but not least the torque generated by permanent magnets and q-current as well as the reluctance torque are calculated.
