<P>PROBLEM TO BE SOLVED: To provide a brushless motor that allows positioning of rotor magnets and balance correction of a rotor while preventing a rise in component cost. <P>SOLUTION: A brushless motor has: a rotor case 11 that has an upper wall 11a and a side wall 11b; a shaft 12 that is fixed to the upper wall 11a; and a rotor 10 that has magnets 13 fixed to an inner circumferential surface of the side wall 11b. A balance weight member 14 is arranged between an inner surface of the upper wall 11a and upper surfaces of the magnets 13. Axial positions of the magnets 13 are restricted by the balance weight member 14. <P>COPYRIGHT: (C)2013,JPO&INPIT |
