Zusammenfassung:PROBLEM TO BE SOLVED: To provide an angle analysis device capable of obtaining correct positional information without initializing at zero before every start of a machine. SOLUTION: The angle analysis device includes: a first resolver 20 which has a first rotor 22 and in which a plurality of the magnetic poles 24 of the first rotor 22 are circularly arranged with an equal interval on the first rotor 22; and a second resolver 30 which has a second rotor 32 coaxial with the first rotor 22 and in which a plurality of magnetic poles 34 of the second rotor 32 are circularly arranged with an equal interval on the second rotor 32 and the number of the magnetic poles 34 of the second rotor 32 is different from the number of the magnetic poles 24 of the first rotor 22.
