摘要： A rotating electrical machine, which is a direct current motor, includes carbon brushes. Each carbon brush contains graphite grains, metal particles, and solid lubricant, which are sintered in a dispersed state. The graphite grains are each formed of granulated substance of raw graphite particles, and the particle diameters of the graphite grains are within a range of 60 to 280 μm. The surface of the granulated substance is coated with amorphous carbon made of carbides of organic binder. A plurality of holes are formed in each carbon brush. The dimension (maximum dimension) of the holes is less than half the average particle diameter of the raw graphite particles.

摘要： The present invention relates to an insulator to be disposed in an armature core having a plurality of radially-formed salient poles. The insulator comprises a winding aligning portion having an approximately V shape (forming an angle of 60 degrees) and getting narrower from an outer side to an inner side in a radial direction of the armature core approximately at the middle between the salient poles to position a winding disposed at a first layer which is a most inner side in the radial direction of the armature core approximately at a middle between the salient poles. By this structure, it is possible to align the windings on the second layer and beyond, thereby preventing a dig-in and the like of the windings and hence preventing faulty insulation between the windings.

摘要： Although a rotor shaft of a spindle motor for driving an optical disc is constituted by stainless steel not to cause damage or friction when the disc is mounted or removed, it is intended to provide a spindle motor which does not require to use a material with bad workability such as stainless steel. A rotor shaft or a rotor cap mounted on the rotor shaft is made from a resin material or an alloy material with good workability such as brass, and a hard coating is provided on its surface to provide hardness necessary for components made of a material with good workability.

摘要： A core insulator fit on a stacked core is formed in a single unit which has tooth cover pieces and coil bobbin piece. The tooth cover pieces are formed to extend in the radial direction and be spaced apart equi-angularly for covering one axial side surface of the stacked core. The coil bobbin piece extends from the corresponding tooth cover pieces in the axial direction to cover the inner side surfaces of slots of the stacked core. The top ends of the coil bobbin piece protrude from the other axial side surface of the stacked core, when the core insulator is fit on the stacked core.

摘要： A magneto-optic disk-driving spindle motor has a rotary shaft for driving a spindle hub. Bearings support the rotary shaft for free rotation. A stator core is fixed relative to the bearings, and a driving magnet is fixed relative to the spindle hub. The spindle hub is provided with an upper side having a magneto-optic disk loading face for receiving and supporting a magneto-optic disk, and an axial part that is to be fitted into the center hole of the magneto-optic disk. A lower side of the spindle hub has a connection for connecting the axial upper end of the rotary shaft to the lower shaft of the spindle hub so as to fix the spindle hub to the rotary shaft. By having the axial part on the spindle hub as opposed to the end of the rotary shaft, the rotary shaft can have a diameter other than the diameter required for engagement with the center hole of the magneto-optic disk.
