PURPOSE:To enable to utilize the induced voltage generated by the rotation of a rotor magnet as a rotating position detection signal by lap winding a drive coil and a rotating position detecting coil on a multipolar stator. CONSTITUTION:Detecting coils 1, 2, 3 are wound on a stator core 6 similar to drive coils 1-1-1-8, 2-1-2-8, 3-1-3-8. A rotor magnet 4 is secured to a rotor yoke 8, and rorates at a rotational shaft 8 as a center. Induced voltages are generated at 1-phase detecting coil 1, a 2-phase detecting coil 2, and a 3-phase detecting coil 3 by the rotation of the magnet 4. The output signals respectively excite the corresponding drive stator coils. |
