Abstract

PURPOSE:To provide well-balanced rotors by forming the magnetic path part of a rotor with resin including a permeable material and the magnetic part with resin including a magnetic material. CONSTITUTION:When applied to an outer rotor type brushless motor, a rotor assembly 8 is constructed of a cup-shape rotor yoke 10 in the bottom surface center of which a boss 9 having a shaft fitting hole 10a to press-fit a motor shaft 6 is formed, and cylindrical or semicylindrical magnets 11 fixed to the inner surface of this rotor yoke 10 by press-fitting or adhesion. The rotor yoke 10 is formed of synthetic resin including a permeable material such as soft ferrite powder, pure iron powder, etc., into a rotating body shape, and the magnet 11 is formed synthetic resin including a magnetic material such as hard ferrite powder, etc., into a rotating body shape.
