ABSTRACT:
A brushless motor has rotor cores dividedly formed as plural sections in an axial direction, segment magnets secured to outer circumferential surfaces of the rotor cores, and magnet holders secured to the rotor cores, respectively, for holding the segment magnet. Each of the rotor cores has holder-positioning grooves to which holder arms are fitted, and bridge parts formed corresponding to the holder positioning grooves. Each of the magnet holders has joint grooves fitted in the bridge parts and displaced from the holder arms by a step angle, the bridge parts being fitted in the joint grooves, thereby assembling a rotor.
