PROBLEM TO BE SOLVED: To provide a brushless motor with a sensor, which facilitates maintenance by facilitating the mounting/demounting of a Hall element sensor required to control revolutions of the brushless motor with the sensor. SOLUTION: A stator 10 is arranged in such a manner as to face a rotor 1; the Hall element sensor 13 is arranged in such a manner as to face a sensor magnet 5; north and south poles of the sensor magnet 5 are detected by the sensor 13; and the timing of a direct-current pulse voltage applied to the stator 10 is controlled according to a detection signal of the sensor 13, so that rotation of the rotor 1 can be controlled. In Fig. 1, both a bearing 3 and the sensor 13 are mounted on a bearing holder 14; a hose cover 12 is removed from a motor sheath 11 by hand (the hose cover 12 and the sheath 11 are coupled together by a screw); and the bearing holder 14 and the sensor 13 can be removed only by removing a holder retainer 15 through use of a tool. |
