PROBLEM TO BE SOLVED: To provide a brushless motor which is thinned and miniaturized and in which magnetic balance is prevented from being lost and the lowering of collected magnetic force is prevented by providing a cut part in a part of the base plate side core plate of an umbrella part in adjacent salient poles of a stator core and disposing a position detector in an air gap formed between the cut part and the base plate. SOLUTION: A stator core formed by laminating a plurality of core plates has a cut part 1c in a part of the core plate 1b on the base plate 5 side of an umbrella part in adjacent salient poles 1a, and a position detector 3 is disposed in an air gap formed between the cut part 1c and the base plate 5. For that reason, the position detector 3 is received inside a slot in the shape of being received in an air gap formed of the cut part 1c and mounted on the base plate 5. Therefore, the motor can be thinned and miniaturized. Further, since a separate cut part 1c is formed in the position where magnetic balance is not lost, the magnetic balance is prevented from being lost. |
