  • Patent number: 8310116
    Abstract: Each of vibration dampers is separated from each circumferentially adjacent one of the vibration dampers upon cutting of each of a plurality of connectors, which is initially integrally formed with the vibration dampers to circumferentially join between corresponding circumferentially adjacent two of the vibration dampers to form a single closed loop body. At least a part of each of first and second circumferential end portions of each vibration damper is engaged with a corresponding one of outer protrusions of a centerpiece in a circumferential direction of a stator. A primary recess is radially inwardly recessed at an outer peripheral portion of the vibration damper and is engaged with a corresponding one of primary protrusions of the stator in the circumferential direction of the stator.
    Type: Grant

  • Patent number: 7745964
    Abstract: In a brushless motor, a stator includes an annular core member. A rotatable shaft is placed radially inward of the core member and extends in an axial direction. A rotor is supported by the rotatable shaft. A centerpiece supports the core member and includes a center portion, which is placed radially inward of the core member. A platy vibration absorbing member connects between the core member and the center portion of the centerpiece and damps circumferential vibrations transmitted from the core member.

  • Patent number: 7659644
    Abstract: A centerpiece rotatably supports a rotatable shaft therein. A stator core is placed radially outward of the centerpiece. A generally cylindrical vibration isolator is made of a resilient material and is radially placed between the centerpiece and the stator core.
