Claims

[Claims for Utility Model Registration] (1) A stator in which stator poles are arranged at equal intervals on the inner peripheral surface of the stator yoke, and a torque coil and a sensor coil for position detection are wound around the stator poles, and a rotor yoke. A rotor having permanent magnets arranged at equal intervals on the surface thereof, and a motor frame having terminals for externally connecting the torque coil and sensor coil on one side thereof and accommodating the stator and rotor, the motor frame having a feedback signal. Double shaft motor. (2) A double-shaft motor with a feedback signal according to claim 1, characterized in that the lengths of the rotor shafts led out in both axial directions are approximately equal. (3) A double-shaft motor with a feedback signal according to claim 1, wherein the terminal is arranged so that the cable is led out in a tangential direction of the rotor. (4) A double-shaft motor with a feedback signal according to claim 1, wherein the rotor is formed in a salient pole shape. (5) The double-shaft motor with a feedback signal according to claim 4, wherein position detection is performed based on a change in reluctance.
