摘要： A rotor for an induction motor includes a first shorting end ring, a second shorting end ring, and a plurality of conductor bars. Each conductor bar has a first end and a second end and is coated with an electrically conductive material. The first end of each conductor bar is in electrical and mechanical contact with the first shorting end ring, and the second end of each conductor bar is in electrical and mechanical contact with the second shorting end ring. The conductive material is disposed between each conductor bar and the respective shorting end rings.

摘要： A method for manufacturing an induction rotor includes placing a lamination stack into a fixture in which the first end of the lamination stack is rotated in an opposite rotational direction from the second end of the lamination stack to skew the conduction bars to an angle α. Vertical members are fixed to an outer perimeter of each of the plurality of laminates of the lamination stack. Hoop members are fixed to each of the plurality of vertical members and an outer edge of each of the plurality of conduction bars. A conduction ring is fixed on each of the ends of the lamination stack. An outer perimeter of the lamination stack is machined to remove the plurality of vertical members and the plurality of hoop members from the lamination stack.

摘要： A method of joining together adjacent overlapping copper workpieces by way of resistance spot welding involves providing a workpiece stack-up that includes a first copper workpiece and a second copper workpiece that lies adjacent to the first copper workpiece. The faying surface of the first copper workpiece includes a projection that ascends beyond a surrounding base surface of the faying surface and makes contact, either directly or indirectly, with an opposed faying surface of the second copper workpiece. Once provided, a compressive force is applied against the first and second copper workpieces and an electric current is passed momentarily through the first and second copper workpieces. The electric current initially flows through the projection to generate and concentrate heat within the projection prior to the projection collapsing. This concentrated heat surge allows a metallurgical joint to be established between the first and second copper workpieces.

摘要： A transmission range selection sensor includes a housing defining a bore extending along a central axis. A piston is slideably disposed within the bore. A magnet carrier is attached to and moveable with the piston. A magnet is supported by and moveable with the magnet carrier. A first magnetic sensor and a second magnetic sensor are supported by the housing and are spaced from each other along the central axis. A position of the magnet carrier along the central axis is determinable from a sensed magnetic flux from the first and second magnetic sensors. The sensor includes at least one magnetic flux concentrator attached to one of the magnet carrier or the housing. The flux concentrator is operable to concentrate the magnetic flux toward at least one of the first magnetic sensor or the second magnetic sensor depending upon a position of the magnet along the central axis.

摘要： A method of resistance spot welding a steel workpiece to an aluminum or aluminum alloy workpiece involves providing a workpiece stack-up that includes a steel workpiece and an aluminum workpiece and preheating the welding electrode that is meant to contact the aluminum or aluminum alloy workpiece. The method further involves pressing the preheated welding electrode and another welding electrode against opposite sides of the workpiece stack-up, with the preheated welding electrode abutting the aluminum or aluminum alloy workpiece, and passing an electrical current between the two welding electrodes at a weld site to initiate and grow a molten weld pool within the aluminum or aluminum alloy workpiece.

摘要： A method of resistance spot welding a workpiece stack-up that that includes an aluminum workpiece and an adjacent overlapping steel workpiece involves assembling the workpiece stack-up so that an intermediate metallurgical additive is positioned between the faying surfaces of the aluminum and steel workpieces. The intermediate metallurgical additive includes at least one of carbon, silicon, nickel, manganese, chromium, cobalt, or copper, and has the capability to counteract the growth and formation of Fe—Al intermetallic compounds within a molten metal weld pool created within the aluminum workpiece during resistance spot welding of the workpiece stack-up. In certain aspects of the disclosed method, the intermediate metallurgical additive may be one or more metallurgical additive deposits that are deposited onto the faying surface of the aluminum workpiece or the faying surface of the steel workpiece by an oscillating wire arc welding process.

摘要： An electrical part testing system for evaluating quality of an insulated electrical part, including a computer-controlled switching apparatus for providing an original voltage to the electrical part automatically according to a pre-established testing scheme calling for provision of voltage to each phase of the part, in turn, while grounding the other phases of the part. A high-frequency filter for receiving receive the original voltage, receiving a load voltage emanating from the electrical part in response to the part receiving the original voltage, and filtering the original voltage from the load voltage to isolate any partial-discharge voltage added to the original voltage by the electrical part while the part is being electrified by the original voltage, yielding a filtered signal. A computing device determines, based on a comparison of a peak amplitude of the partial-discharge inception voltage to a voltage threshold, the quality of the electrical part being tested.

摘要： A continuity tester that has particular application for inspecting the insulation on the stator windings in an electric machine. The continuity tester includes a power supply, a brush having conductive bristles, and an analog-to-digital (A/D) converter. One terminal of the power supply is electrically coupled to the brush and another terminal of the power supply is electrically coupled to the A/D converter and the stator being tested. The conductive brush is selectively positioned against the exposed windings of the stator, and if an electrical circuit is formed as a result of loss of insulation, the potential at the input of the A/D converter drops, which can be detected. In one embodiment, the conductive brush is a manual brush that is moved across the stator windings, and in alternate embodiments the conductive brush is specially configured to be positioned against the conductive windings in an automated process.
