PROBLEM TO BE SOLVED: To provide a two-shaft composite motor that is small, that is well controllable, and that makes high-precision positioning possible. SOLUTION: A rotary motor 6 consisting of a rotor 6a and a stator 6b, and an circular-arc motor 4 consisting of a stator 4b mounted to the rotor 6a of the rotary motor 6 and a rotor 4a, are provided. The rotor 4a of the circular-arc motor is mounted to one side of the spherical inner ring 2a of a spherical bearing 2 via a shaft 3. An output shaft 1 is mounted to the opposite side of the shaft 3 mounted to the spherical inner ring 2a of the spherical bearing. Two pieces each at one side of rolling guide plungers 5a are arranged on the rotor 6a of the rotary motor. By pressing the plungers 5a to both side surfaces of the rotor 4a of the circular-arc motor with a spring 5c, an output of the rotary motor 6 is transmitted to the output shaft 1 of the circular-arc motor.
