A rotor type brushless motor comprises a drive magnet having an indexing pole part that extends on one axial side thereof. This indexing pole part is formed at least in the range from the circumferential center of one north pole to the circumferential center of one adjacent south pole, and over no greater than the range from one circumferential end of the one north pole to the other circumferential end of the one south pole. A magnetic flux detector is arranged at a position axially facing the indexing pole part.
