PROBLEM TO BE SOLVED: To provide a brushless motor in which a thrust force is acted on a rotor, easy to manufacture, with a simple structure.SOLUTION: The brushless motor includes: a stator 200 having a stator core 102 and a stator coil 104; a rotor magnet 114 rotatable around a center axis against the stator 200; and a Hall sensor 107 facing an end surface on a lower side of the rotor magnet 114 in the direction of the center axis. At a surface on a side facing the stator core 200 of the rotor magnet 114, a circumferential groove 115 is formed at a position deviated to a lower side.SELECTED DRAWING: Figure 1 |
