摘要： A rigid disk drive spindle motor includes a bobbin carried by the motor hub which has a permanent magnet attached to the inner cylindrical surface and a laminated back iron mounted at the outer cylindrical surface. The laminated back iron may be in the form of concentric cylinders or a spiral wound strip with adjoining cylinders or convolutions secured to and electrically separated from one another by an adhesive material. In another form, the back iron may be formed as a series of washer like rings mounted on the bobbin which is a configuration similar to the laminations used in the motor stator and would permit fabrication using the same manufacturing techniques. The back iron is formed of high resistance silicon steel so that both the back iron material and the laminated structure discourage Eddy current formation. The spiral wound embodiment may also be modified by having the spiral strip periodically, axially interrupted to further reduce undesired induced currents. Use of the bobbin serves to assure the concentricity of the closely adjoining stationary and rotary parts of the spindle motor and to facilitate easier manufacture and assembly. To further confine the magnetic fields, laminated fringe ring assemblies are provided at each axial end of the back iron structure. These assemblies are formed of washer like rings of permeable material that are secured to one another and electrically separated by adhesive material.

摘要： A magnetic fluid seal is provided by mounting an annular, axially polarized magnet mounted on the device base member and an annular ring pole piece with an inner diameter that cooperates with an outer diameter surface of the hub assembly to form a fluid gap that is radially outward and within the axial extent of the spindle bearings. The secondary gap of the seal assembly is within the bearing assembly sealed volume while the principal sealing gap is within the hub assembly to confine any debris or aerosols resulting from high rotational velocity or shock to be contained in proximity to the flux fields that can recapture any magnetic material. The assembly also inherently presents an effective conductive path to provide enhanced grounding of the rotating assembly through the magnetic fluid in the second gap which is not subject to impairment caused by bonding materials. The seal assembly design also provides for self loading of the magnetic fluid without permitting escape of smeared liquid beyond the region of the seal assembly.
