Summary:PROBLEM TO BE SOLVED: To provide a smooth core armature type three-phase brushless motor, which is excellent in performance and easy of manufacture by improving a short-pitch coefficient. SOLUTION: This smooth core armature type three-phase brushless motor is equipped with a rotor in which a plurality of permanent magnets 2 are arranged at equal intervals on the surface of an iron core 4 so as to constitute mutually different poles, a stator arranged facing the rotor via an air gap, and a plurality of coils 1 of non-lap concentrated winding on a stator core 3. The number of the coils 1 is 6n, and the number of poles is 10n ((n) is a natural number). As a result, a short-pitch coefficient is improved so that a smooth core armature type three-phase brushless motor of high output can be obtained.
