Abstract: To provide a brushless motor capable of performing miniaturization and reduction in weight and enhancing reliability by eliminating a crossover.SOLUTION: Adjacent paired teeth TH are set as a set, and coils of the same phase (Cu and Cu, Cv and Cv, Cw and Cw) are wound around the paired teeth TH as a set. As a result, the number of coil ends in the paired teeth TH as a set can be reduced to two, and these can be pulled out to one side in the axial direction of a stator core 21. Therefore, a drive circuit (delta connection or star connection) of the brushless motor 10 can be formed by connecting the coil ends on one side in the axial direction of the stator core 21. Therefore, it is possible to eliminate the "crossover" that connects the coils of the same phase arranged at an interval of 90 degrees on the other side in the axial direction of the stator core as in the past. Therefore, it is possible to perform miniaturization and reduction in weight and also enhance the reliability of the brushless motor 10.SELECTED DRAWING: Figure 2
