Converter between electrical threephase and mechanical domian
Extends from Modelica.Mechanics.Rotational.Interfaces.PartialElementaryOneFlangeAndSupport2 (Partial model for a component with one rotational 1-dim. shaft flange and a support used for textual modeling, i.e., for elementary models).
Information
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.
