PROBLEM TO BE SOLVED: To provide a brushless motor in which the cost can be reduced by reducing assembling man-hour. SOLUTION: Stator 29 of a brushless motor 1 comprises a flux plate 9 provided on a base member 3, a circuit board 13 provided on a flux plate 9, only one coil 23 provided on the circuit board 13, a Hall element provided on the circuit board 13 in order to detect magnetism of magnets 34-37 of the rotor 19, a drive IC 27 provided on the circuit board 13 in order to control a current supplied to the coil 23, and a weight 39 provided on the rotor 19 out of balance. The rotor 19 is provided with magnets 34-37 of quadrupole and rotates about a shaft 15 supported on the base member 3. COPYRIGHT: (C)2007,JPO&INPIT
