Rotator

Rotates space phasor

Information

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

Rotates a space phasor (voltage or current) input u by the angle in negative mathematical direction. This block represents the transformation of one space phasor u from one rotating reference (coordinate) frame into another where the space phasor is y. The output reference frame leads the input reference frame by angle angle.
