Abstract
A coordinate converter useful for field-oriented control of a rotating-field machine includes a divider, a first adder, a multiplier and a second adder by which the magnitude of the vector and the tangent of the half-angle relative to one axis can be determined. An ancillary unit forms an angle-proportional variable from the half-angle tangent. A rotating vector can also be processed.
