Abstract

PURPOSE:To make a motor highly efficient, small-sized and light in weight with the field reinforced, by enhancing field density to the same pole with the field region in object of a drive winding narrowed. CONSTITUTION:A brushless motor 10 is equipped with a ring stator 12, a disc rotor 14 and a cover 15. The ring stator 12 supports the output shaft of the rotor 14 through bearings 16 and 18. Drive windings 22, 23 and 24 of the 1st to 3rd phase are arranged to the ring stator 12. The ring stator 12 is equipped with an internal ring pole 26, an external ring pole 28 and a central ring segment pole 30. Ring spaces 32 and 34 are formed respectively between in- and external ring poles 26 and 28 and the central ring segment pole 30. Drive windings 22, 23 and 24 are arranged inside the ring slots 32 and 34 different in radius of curvature. The rear of the in- and external ring poles 26 and 28 and the central ring segment pole 30 is magnetically connected with a stator yoke 36.
