機。A magnetic yoke fixed to a rotating shaft includes a motor rotor section in which an annular magnet magnetized with multiple poles is arranged concentrically with the rotating shaft, and a drive coil that applies rotational torque to the motor rotor section. a motor stator portion disposed on a coil yoke facing the magnet and concentric with the rotating shaft; a rotor for a frequency generator formed by magnetizing into multiple poles at an inner peripheral end of the magnet; A power generating coil that faces the rotor for the frequency generator and generates a frequency signal according to the rotational speed of the motor rotor is mounted on an insulating substrate inserted between the motor rotor and the motor stator. A stator section for a frequency generator formed by printed wiring is provided, in which the stator section 6j for the frequency generator and the generating coil are arranged in a rectangular wave shape at a predetermined pitch in the circumferential direction around the rotation axis. At the same time, a ring-shaped external magnetic flux canceling conductor is arranged inside this generating coil and connected in series with the generating coil, and one end of the generating coil and one end of the external magnetic flux canceling conductor are connected in the radial direction. It is characterized by being configured so that the magnets are drawn out in parallel to each other, and are drawn out so that they intersect at a position that is 1/2 of the radial distance between the outer circumferential circle formed by the generating coil and the outer circumferential circle of the magnet.
