摘要： A magnetic armature wedge is provided for replacing conventional dovetail wedges in high-powered large-size turbine generators. The magnetic armature wedges that are used for supporting the armature bars are made by molding resin, e.g., epoxy with ferromagnetic particles, wires, laminates and the like embedded therewithin. The magnetic particles, wires, laminates and the like increase the magnetic permeability of the wedges causing higher slot flux leakage and high generator subtransient reactants.

摘要： This invention provides a rotating electric machine using an inner section of a slot of a stator as a cooling passage and allowing a high cooling efficiency. Furthermore, it provides a manufacture method for the rotating electric machine which allows streamlining of the manufacture of the cooling passage. A plate is attached to the plate retaining groove formed in proximity to the opening of the slot of the stator. A resin layer is formed by injection of resin into a space formed between the outer face of the plate and the mold set on an inner peripheral face of the stator. The plate is pressed by the injection pressure of the resin to come into close contact with the stopper and to create a seal which prevents leakage of resin into the slot. A leg is provided on the plate and extends into the slot for reducing the cross sectional surface area of the cooling passage

摘要： The stator includes core back iron cores disposed on outer circumferential sides between a plurality of teeth iron cores disposed at regular intervals of a predetermined distance in a predetermined circumferential direction. A stator winding is disposed on inner circumferential sides between the plurality of teeth iron cores. The stator winding is constituted by a plurality of wire bundles each of which is a bundle of a predetermined number of electric wires and which are connected in parallel with one another. The wire bundles are set so that the number of electric wires constituting a wire bundle located on the inner circumferential side between adjacent teeth iron cores is smaller than the number of electric wires constituting a wire bundle located on the outer circumferential side. Hence, the ratio (L/A) of the circumferential length L of each wire bundle to the sectional area A thereof is set at a value in a predetermined allowable range.

摘要： A brushless DC motor minimizes a chance of dislocation of or damage to an insulator used in the brushless DC motor. Slant portions are provided at end portions of the insulator; therefore, even if a nozzle of a machine for installing a winding should hit the insulator while moving between teeth, the insulator moves in a direction for coming in close contact with a slot aperture, i.e., in a direction substantially at right angles to a direction in which the nozzle moves. This arrangement prevents the insulator from moving by being pushed by the nozzle, making it possible to minimize a chance of occurrence of an insulation failure caused by a damaged or dislocated insulator.

摘要： A dynamoelectrical machine (20) has winding bars (13) which are inserted into slots provided for this purpose in the dynamoelectrical machine (20), with the slots each being closed by cover wedges (23), and with corrugated springs (16) being provided between the cover wedges (23) and the winding bars (13) located underneath them, which are prestressed by means of opposing wedges (21), which are arranged between the cover wedges (23) and the winding bars (13) located underneath them. In a machine such as this, fast and simple wedging is made possible in that the opposing wedges (21) are arranged between the cover wedges (23) and the corrugated springs (16), and in that fixed-position adjusting elements (22) are provided, by means of which it is possible to vary the distance between the cover wedges (23) and the opposing wedges (21).
