modelRotorDisplacementAngle
Rotor lagging angle
Information
Calculates rotor lagging angle by measuring the stator phase voltages, transforming them to the corresponding space phasor in stator-fixed coordinate system, rotating the space phasor to the rotor-fixed coordinate system and calculating the angle of this space phasor.
The sensor's housing can be implicitly fixed (useSupport=false).
If the machine's stator also implicitly fixed (useSupport=false), the angle at the flange
is equal to the angle of the machine's rotor against the stator.
Otherwise, the sensor's support has to be connected to the machine's support.
