PROBLEM TO BE SOLVED: To detect the position of a rotor with improved accuracy by using a Hall element.SOLUTION: A magnet 1 included in a rotor part 2 has a projection 1a projecting from a stator core 3 of a stator part 5 in an axial direction of a shaft 10. A Hall element 7 is installed at a resin member 4 of the stator part 5 facing the projection 1a in a radial direction of the shaft 10 and detects a rotational position of the magnet 1.SELECTED DRAWING: Figure 1 |
