ABSTRACT:
In a DC brushless motor, a position detecting magnet (1b, 31b) is arranged in correspondence with a driving magnet (1a, 31a) which is for causing torque, and the position detecting magnet (1b, 31b) includes a non-magnetized part in each pole to make a predetermined distribution of flux which can be detected by only one magnetic detecting element (7); and signals detected by the magnetic detecting element are developed into three (or two)-phase full-wave driving signals through a necessary signal processing circuit (14) etc.
