OUTER ROTOR TYPE MOTOR AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an outer rotor type motor that reduces a top surface deflection by improving the squareness between a rotor shaft and a rotor yoke.SOLUTION: The outer rotor type motor is so configured that a yoke opening side of a yoke top surface part 10c of a rotor yoke 10 formed in a cup shape is supported by overlapping with a receiving piece 16, a rotor shaft 9 is press fit into a shaft hole 10b from a yoke opening side by pressing a shaft hole outer peripheral edge part on the opposite side of a receiving piece support surface with a press piece 14, and the rotor shaft 9 is integrally assembled to the rotor yoke 10 by applying forging press to the shaft hole outer peripheral edge part with the press piece 14.SELECTED DRAWING: Figure 3
