Abstract
In a position transducer having detection coils 11 and 21, auxiliary coils 12 and 22 are driven in phase with the detection coils 11 and 21 and are lap-wound on the ends of the detection coils to substantially increase the winding density at the ends of the detection coils 11 and 21, thereby reducing the magnetic field non-linearity at the coil ends.
