PROBLEM TO BE SOLVED: To provide a compact absolute rotary encoder capable of carrying out a precise measurement. SOLUTION: Tracks 41, 43 are arranged concentrically on a rotor 3. The track 41 is arranged outside as capable of flux coupling with a receiving winding 17 and a transmitting winding group G2. The track 43 is arranged inside as capable of flux coupling with a receiving winding 19 and the transmitting winding group G2. Respective tracks 41, 43 are flux coupling windings 51, 53 each in the form of a continuous ring about a shaft 9. Numbers of blocks 61 making up the flux coupling windings 51, 53 are ten for the track 41 and nine for the track 43. COPYRIGHT: (C)2007,JPO&INPIT
