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.
