PROBLEM TO BE SOLVED: To provide a motor the axial thickness of which can be reduced, by mounting a position detection element of a rotor and a rotated position detector on the motor.SOLUTION: A motor 1 has rotary section and a stationary section 3. The rotary section has a shaft 21, a rotor holder 22 fixed to the shaft 21, and a rotor magnet 23 fixed to the rotor holder 22. The stationary section 3 has a mounting plate 31, an armature 32 held directly or indirectly by the mounting plate 31 on the radial outside thereof, a bearing member 33 held on the radial inside of the mounting plate 31, and a circuit board arranged on the underside of the armature 32. The circuit board includes a rotational position detecting element, which is arranged on the underside of the axial end of the rotor magnet 23. An output part 213 of the shaft 21 projects from the upper side of the rotor holder 22, and the shaft 21 has a housing section 214 for housing a rotated position detector at the axial lower end. |
