The Rotor Displacement Angle component calculates the 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 ($\mathrm{use\; support}\=\mathrm{false}$). If the machine's stator also implicitly fixed ($\mathrm{use\; support}\=\mathrm{false}$), 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.
