PROBLEM TO BE SOLVED: To provide an induced current position transducer for reducing spatial phase errors associated with layout constraints. SOLUTION: Each of windings 510A, 510B, and 510C of the transducer comprises a set of loops arranged in hypothetical basic polarity zones PZ that alternate along the measuring axis and a set of loops arranged in hypothetical offset polarity zones OPZ that are offset from the basic polarity zones along the measuring axis. Hypothetical offset zones are defined at positions where basic and offset polarity zones that have opposite polarities overlap. Due to layout constraints, each winding may have an offset zone including an unbalancing coupling area that differs from the coupling area in the majority of offset zones. The windings are configured such that the amount of unbalanced coupling area included in the offset zones of each winding is approximately the same for each of the windings, making their respective phase errors approximately the same.
