Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
A synchronous machine with permanent magnets, current controller and measurement noise of ±0.01 rad 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 of model SM_PermanentMagnet are used.
This motor is used in the Examples.Noise.ActuatorWithNoise actuator example
