A coordinate converter distinguished by low cost of hardware and useful for the field-oriented control of a rotating-field machine contains two multipliers, an adder and a subtraction element in a logic circuit. Optionally, two proportional elements can be added thereto. With this coordinate converter, the two Cartesian coordinates can be determined. If the magnitude is constant, the coordinate converter can be used as a sine-cosine generator. In addition, a supplemental circuit for generating a rotating vector is described. |
