PROBLEM TO BE SOLVED: To provide a DC brushless motor having notch parts or air gaps part in the stator core in which pulsation of cogging torque can be reduced. SOLUTION: The DC brushless motor is provided with notch parts 2a or air gaps parts in the vicinity of the outer circumferential side of a part of tees 3a in the stator core 1a formed by laminating a plurality of steel plates. The steel plates are laminated while being displaced by a specified angle in the circumferential direction such that the length of the notch part 2a or air gap is substantially constant in the laminating direction for each tees 3a. |
