PROBLEM TO BE SOLVED: To provide a single phase brushless motor, in order to reduce the size of a motor body by fitting a coil bobbin with a printed circuit board integrating a sensor and a power feed control circuit. SOLUTION: A printed circuit board 10 mounting a sensor 11 to sense the magnetic pole of a rotator magnet 5 and a power feed control circuit 12 to switch the feeding direction of an armature coil 4 depending on the magnetic pole position of the rotor magnet 5 is fitted to a coil bobbin 3, and the sensor 11 mounted to the printed circuit board 10 is structure to detect the magnetic pole of the rotor magnet 5 from an aperture 9 formed in a bracket 6a. |
