PROBLEM TO BE SOLVED: To provide a device for a body of revolution capable of accurately sensing a rotor member and accurately controlling according to a temperature of the rotor member. SOLUTION: The device for body of revolution equipped with a stator member 18 and a rotor member 14 coaxially located with the stator member 18 on the outside of the stator member 18 rotated by a motor 21 fixes a magnet forming a magnetic field with a determined strength at an outside perimeter of stator member 18, fixes a circuit 60 containing the first coil 61 inducing a voltage alternating magnetic field with a magnetic field due to a magnet 71, the second coil 62 generating a magnetic field by a voltage due to the first coil 61 at the opposite face of the rotor member 14 and a thermistor 63 intervened between the first coil 61 and the second coil 62, fixes a sensor for sensor 71 alternating a magnetic field by the second coil 62 at an outside perimeter of the stator member 18 and senses a temperature of the rotor member 14 based on electric current generated due to the coil for sensor. |
