PROBLEM TO BE SOLVED: To miniaturize an entire part by directly connecting a resolver for detecting the rotary position of a servo motor in a weak magnetic field using an air-core coil to the servo motor in one piece. SOLUTION: In a resolver 10, a plurality of air-core coils are arranged at a stator 11 in one end of a rotary shaft 3 of a servo motor 1, a rotor 12 is provided while it faces the air-core coil of the stator 11, and the rotary position of the servo motor 1 is detected with a weak magnetic field. At this time, the stator 11 is fixed to a bracket part 5 of the servo motor 1 by a set screw 14 via an adapter 13, and the shaft part of the rotor 12 is fixed to a rotary shaft 15 of the resolver 10 by a set screw 16 so that they can be rotated in one piece, thus miniaturizing an entire part without being affected by usage environment. |
