PROBLEM TO BE SOLVED: To provide a downsized induction detection type rotary encoder.SOLUTION: The induction detection type rotary encoder has a counter face of a first rotor of a stator and a counter face of the stator of the first rotor that have a first angle detection track and a second angle detection track coaxially formed with an equivalent diameter with respect to a rotary shaft. Further, the rotary encoder has a counter face of a second rotor of the stator and a counter face of the stator of the second rotor that have a third angle detection track and a fourth angle detection track coaxially formed with the equivalent diameter with respect to the rotary shaft. The first to fourth angle detection tracks respectively generate a N1 to N4-time periodic change by one rotation of the first and second rotors, where N1 is different from N2, and N3 is different from N4. |
