  • Patent number: 11509176
    Abstract: A rotating electrical machine is equipped with a rotor and a stator. The rotor includes a magnet unit and a rotor core retaining the magnet unit. The rotor core is made of a stack of annular core plates and an annular end plate mounted on an end of the stack of the core plates. The end plate has a deformable wave shape. The stack of the core plates and the end plate has formed therein through-holes extending through a length thereof. Bar-shaped fastening members, such as rivets, which have flanges on ends thereof are inserted into the through-holes with the flanges pressing the end plate to elastically deform the wave shape of the end plate, thereby tightly gripping the stack of the core plates in the lengthwise direction. This minimizes concentration of stress on the core plates to eliminate a risk of damage or breakage of the rotor.

  • Patent number: 9209668
    Abstract: Provided is a spindle motor having an electrostatic discharge (ESD) path that can stably discharge electric charges introduced from the outside to a rotating shaft through a base plate, in a structure of forming a bearing housing by using a resin and insert-molding the base plate. The spindle motor includes: a rotor to the central portion of which one end of a rotating shaft is coupled; a bearing that rotatably supports the rotating shaft; a bearing housing that accommodates the bearing in the inside of a groove and that is made of a resin; and a base plate whose inner circumferential portion is buried and combined in the inside of the bearing housing, wherein part of the base plate is in contact with the bearing to thus discharge externally introduced static electricity through the rotating shaft, bearing, and the base plate.

  • Patent number: 9209655
    Abstract: A motor's stator unit includes a base and a stator. The base has a shaft tube. The stator has a silicon steel plate unit, an insulation sleeve unit and a coil unit. The silicon steel plate unit has an inner circumferential wall forming a through-hole. The insulation sleeve unit has an engagement hole. The silicon steel plate unit and the insulation sleeve unit are stacked together. An enameled copper wire is wound around the insulation sleeve unit to form the coil unit. The engagement hole has a minimal diameter that is slightly smaller than an outer diameter of the shaft tube. The stator is press fit around the shaft tube via the insulation sleeve unit, to prevent the silicon steel plate unit of the stator from excessively compressing the shaft tube.

  • Patent number: 9136746
    Abstract: A stator includes a hollow cylindrical stator core comprised of a plurality of stator core segments, a stator coil mounted on the stator core, and an outer cylinder that is fitted on the radially outer surfaces of the stator core segments so as to fasten the stator core segments together. The stator core has a recess formed in the radially outer surface of one of the stator core segments. The outer cylinder has a slit that radially penetrates the outer cylinder to connect the radially outer and inner surfaces of the outer cylinder and an engaging portion that adjoins the slit. The engaging portion of the outer cylinder is plastically deformed radially inward into the recess of the stator core so as to abut and thereby engage with side walls of the recess which face the engaging portion.

    Abstract: Certain exemplary aspects of the present disclosure are directed towards an apparatus in which a base deck and a base deck cover interface with one another to provide a permeability path. The base deck includes an outer region, and the base deck cover includes a lip that interfaces with the outer region of the base deck to provide the permeability path. The permeability is further defined by at least three interleaved sidewalls of the base deck and base deck cover that define two segments of the permeability path. The permeability path is filled with a polymer material that creates a seal between the base deck and base deck cover.
