BRUSHLESS MOTOR AND METHOD OF PRODUCING ROTOR

WIPO Patent Application WO/2024/079930

A1

In the present invention, a first annular convexity 75 supporting an axially distal end of a magnet 63 is provided to a portion of another side surface 74 of a stopper plate 70 facing the magnet 63. A second annular convexity 76 supporting an axially distal end of a rotor body 62 is provided to a portion of the another side surface 74 of the stopper plate 70 facing the rotor body 62. A communicating path 75a creating communication between a radially inward side and a radially outward side of the first annular convexity 75 is provided to the first annular convexity 75. When a rotor 60 is being assembled, air flows gently through the communication path 75a, and adhesive bulging out of a first adhesive-accommodating recess 77 of the radially inward side of the first annular convexity 75 will not burst out into a second adhesive-accommodating recess 78 of the radially outward side of the first annular convexity 75. The foregoing enables improvement in the ease of assembly.
