Abstract

PURPOSE:To reduce the parts to be used, and to obtain a brushless motor at a low cost by a method wherein the number of poles of permanent magnets, the number of grooves to accommodate windings and being provided in a stator core, and the number of stator windings are set at the specified numbers, and the winding pitch for one winding is constituted as the same with the pitch for one pole of the permanent magnets. CONSTITUTION:The number of P of poles of the permanent magnets 13 provided in the stator is made as 4, the number S of the grooves provided in the stator core 14 as 12, the number N of the stator windings as 8, and the ratio P/S between the number P of poles of the permanent magnets and the number S of the grooves provided in the stator core is made to be a positive integer of 2 or more, and moreover the number N of the windings and the number P of poles of the mangets are made to have the relation N=2P, and one pitch of the windings is constituted as to be euql with one pole pitch of the magnets. Accordingly the brushless motor being suitable for the specific use of fun driving, etc., and constituted at the low cost reducing the parts to be used can be obtained.
