摘要： Slot wedges, electrically-conductive, used in rotor slots, between rotor teeth, and overlying the rotor coils, are serially arranged in the slots and have arcuate grooves in opposite ends thereof. Inserts, also electrically-conductive, are spring-loaded in the grooves to effect electrical continuity fully therealong, lengthwise of the rotor, from wedge to wedge.

摘要： The present invention provides enhanced electromagnetic radiation transmission by providing an electrically conductive lamination between the silicon iron laminations in transformers, motors, alternators and solenoids. The conductive laminations increase the transmission of electromotive force and enhance cooling. An alternative to providing conductive laminations in a laminated core or stator is to provide a solid sintered metal core including iron, silicon and a conductor. Each transformer also includes a conductive amplifier coil connected in series with the primary coil and circling the primary coil and another conductive coil connected in series with the secondary coil and circling the secondary coil. The coils take advantage of the negative induction current described by Lenz's law to increase efficiency. In a motor, the stator laminations are optionally surrounded by a conductive amplifier coil which produces an amplification effect. The resulting transformer, motor or generator has increased efficiency, decreased input current, decreased loss resulting in a decrease in operating temperature.

摘要： An induction motor includes a stator having at least one pair of stator windings and a rotor with rotor windings which are magnetically coupled to the stator windings via a circumferential air gap. The rotor windings are connected together in a squirrel cage or a wound rotor configuration. The stator windings are connected in series across the source. A capacitor is connected in parallel with one of the stator windings and this combination is connected in series with the other stator winding and is sized to form a quasi-double-resonant circuit, i.e., a quasi-parallel resonant circuit with the one winding and a quasi-series resonant circuit with the other winding. The stator windings are then grouped to form definite polar areas in the stator and a balanced rotating magnetic field is produced by all the windings throughout the entire load range when the motor is connected to a power source. Both a single-phase and a polyphase motor can be configured as a quasi-double-resonant circuit with respect to each input power phase. A further polyphase motor is also described with primary stator windings connected to each power phase input and interleaved secondary stator winding magnetically coupled to the primary stator windings but not directly connected to the power inputs. The secondary stator windings have capacitors coupled in parallel thereto to form parallel floating resonant circuits. In all of these motors, the power factor is in the range of 0.96 to 1.00, but normally closer to unity due to the resonant behavior of the circuitry. The induction motor can be driven above synchronous speed to act as a generator. Also, a method of generating torque is described.

摘要： A method and apparatus for locking the wedges used in a dynamoelectric machine having a radically ventilated rotor keys each wedge to its respective damper bar. By inserting a solid key in a selected keyway proximate to a point midway along the length of the rotor, and inserting split keys elsewhere, accumulated axial migration of the wedges relative to their respective damper bar is limited thereby ensuring adequate ventilation through the radically extending ducts.

摘要： A damper winding for the rotors of large turbine generators to shield the rotor surface and windings from non-synchronous fluxes, or to reduce the negative resistance of the generator. The damper winding consists of longitudinal bars of low resistance material placed on the surface of the rotor over each tooth, including teeth formed on the pole face portions. The bars have longitudinal recesses to fit over the teeth and engage in the slot on each side for mechanical support of the bar, and the bars are in electrical contact with each other throughout their length to form a continuous conducting surface.
