Abstract

PURPOSE: To make it possible to secure arrangement precision of a detection coil easily by constituting a detector with an excitation-coil printed board fixed to a magnetic pole plate and a detection-coil printed board to a rotor.
CONSTITUTION: Detection-coil printed board 4, fixed to one terminal surface of rotor 2 formed of a magnetic substance with ring-shaped groove 3 has printed detection coil 5 having an area in parallel to the fixed diameter. On magnetic pole plate 6, magnetic poles 8 to 11 are arranged confronting to the above-mentioned printed board 4; the 1st excitation coil 12 and the 2nd excitation coil 13 are wound around magnetic poles 8 and 9, and 10 and 11 respectively. Then, output signal POS of oscillator OS is divided to generate a phase difference signal, and an excitation signal is supplied to excitation coils 12 and 13 to generate an alternating- current magnetic field by magnetic poles 8 and 9, thereby turning the above print board 4 by a certain angle. By using a detection signal from detection coil 5, at this time, phase difference signal Pd is outputted from phase comparator PR and pulses corresponding to the rotation position of rotation position detection part A are counted.
