  • Rotating shaft and motor rotor having the same
    Patent number: 7888835
    Abstract: A rotating shaft disclosed by the present invention includes a plurality of bumps spacedly formed along an outer circumferential surface thereof. The bumps are each formed with two engagement portions extending outwardly and bilaterally and a deformation space therebetween. The engagement portions undergo resilient deformation toward the deformation space when subjected to a force, thus providing stable engagement with a magnetic body, protecting the magnetic body from cracks and damages during assembling, and enhancing yield. The present invention further discloses a motor rotor having the above-described rotating shaft.
