PROBLEM TO BE SOLVED: To provide a concentrated-winding type brushless DC motor capable of attaining less noise and less vibration. SOLUTION: This DC motor is structured so that the area of a slot section is decreased to be within a range such that lowering motor output is substantially restrained, by increasing the layering thickness of a stator board so as to ensure the rigidity of a stator. The stator is structured so that the ratio of the outside diameter of the stator to yoke width and teeth width lies within a predetermined setting range. COPYRIGHT: (C)2003,JPO |
