Claims

[Scope of utility model registration request]

A rotor has permanent magnets on its inner circumferential surface with N and S poles magnetized alternately at equal intervals in the circumferential direction, and the outer circumferential surface formed by the tips of the plurality of magnetic poles is smaller than the inner circumferential surface of the permanent magnet. a stator section consisting of stator cores disposed opposite to each other with a gap in between; a base that rotatably supports the rotating shaft of the rotor at its inner circumferential section and has the stator section mounted at its outer section; In the above-mentioned brushless motor equipped with a magnetic detector that detects the rotational position of the permanent magnet and is provided on the wiring board facing the permanent magnet, a holder that positions and holds the magnetic detector is integrated into a base that fixes the wiring board. A brushless motor comprising:
