The utility model provides a motor. A rotating part of the motor is provided with a shaft, a rotor holder, a magnet holder made of resin, and a plurality of magnets. The magnetic holder is provided with a base part and a plurality of arm parts, and the plurality of arm parts are extended from the base part toward a radial outer part of the rotor holder. The plurality of magnets are respectively disposed among the plurality of arm parts, therefore the positioning of the magnets in the peripheral direction can be realized. Because the base part is disposed on the position, which is overlapped with the positions of the magnets in the radial direction, therefore the axial lengths of the magnets are not limited. The axial lengths of the magnets can be prolonged, and the strong magnetic force can be achieved, in addition, the peripheral widths of the arm parts are shorter than the radial lengths of the arm parts. The peripheral lengths of the magnets can be prolonged, therefore the stronger magnetic force can be achieved. |
