    摘要: In a position transducer having detection coils 11 and 21, auxiliary coils 12 and 22 driven in phase with the detection coils 11 and 21 are lap-wound on the ends of the latter, respectively, 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.

    摘要: A position transducer includes a bias circuit 46 which drives and controls first and second bias coils 27a and 27b. The bias circuit 46 monitors the value of a voltage produced in a second sensor coil 29b, and drives and controls the first and second bias coils 27a and 27b for the value of the voltage produced in the second sensor coil 29b to always be equal to a desired voltage value.
