Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

A synchronous induction machine with permanent magnets accelerates a quadratic speed dependent load from standstill. The rms values of d- and q-current in rotor fixed coordinate system are converted to three-phase currents, and fed to the machine. The result shows that the torque is influenced by the q-current, whereas the stator voltage is influenced by the d-current.

Default machine parameters are used.
