PROBLEM TO BE SOLVED: To provide a DC brushless motor which makes it possible to improve the output voltage of a pole position detector by improving the magnet, to stabilize the rotation of the motor and to realize a low-cost by extending the selection of the detectors. SOLUTION: A magnet 7 is mainly magnetized in the direction for forming an air gap to a stator S and magnetized in an end face direction different from the magnetizing direction thereby to form a detecting magnetic field at the surface opposed to a pole position detector 9. Thus, the detector 9 sends the stable output voltage to a motor drive IC side without depending upon the leakage magnetic flux of the main magnetization. |
