摘要： Active compensation in the form of a pair of trim coils and passive compensation in the form of a solenoidal-shaped magnetic shunt are disclosed for shaping the magnetic field existing in the liquid metal current collector region of an acyclic generator such as to minimize the field component normal to the stator and rotor collector surfaces and thereby substantially eliminate the generation of circulating currents in the liquid metal medium.

摘要： A laminated rotor for a dynamoelectric machine characterized by requiring and incorporating only two differently configured sets of rotor laminations to afford axial and radial coolant passageways through the rotor. Each lamination in the respective sets is provided with punched apertures that form, respectively, conductor slots arcuately spaced around its periphery, and is further provided with a plurality of axial coolant passageways near its inner diameter. Each lamination in one of the sets of laminations also includes a plurality of arcuately spaced radial ducts, each disposed between a respective pair of conductor slots. The axial coolant passageways in one set of laminations are arranged to overlap a predetermined portion of the inner ends of the radial ducts in the other set of laminations to enable cooling air to be forced through the axial coolant passageways into the radial ducts and then into the air gap of the machine when the sets of laminations are stacked to form a rotor that is then mounted in operating position, relative to an associated stator.

摘要： A magnetic wedge for use in toothed stators holds the stator windings in the slots formed between the teeth of the stator. The magnetic slot wedge comprises a nonmagnetic body, with a width corresponding to the width of the slot. The nonmagnetic body has parallel laminations of magnetic material extending part way through the width of the magnetic body from both sides of the magnetic body and perpendicular to the top surface. A central nonmagnetic region is thereby created with a region on either side of the central portion having an average permeability, along its length, substantially in the range of about 5-10.

摘要： A rotor analyzer for an induction motor or generator checks and quantifies the integrity of a rotor that is not currently installed within its stator. The analyzer includes an electromagnetic coil that exposes the bars of a rotor to a pulsating magnetic field to induce a current through the bars. At the same time, the rotor is slowly rotated to sequentially expose each bar. A magnetic field created by the induced current in the bars induces an analog signal within a search coil. The analog signal is converted to digital and inputted to a microprocessor system. The system interprets the input data and manipulates it to provide a clear, understandable indication of the rotor's condition, such as the relative impendence of each bar. The system also determines how many bars are within a rotor having an unknown number of bars.

摘要： A rotor assembly for a dynamoelectric machine is characterized by incorporating three different sets of rotor laminations each of which is provided with punched apertures that respectively form conductor slots arcuately spaced around the periphery of the laminae, a plurality of axial coolant passageways extending through the assembly near its inner diameter, a plurality of arcuately spaced radial ducts at axial intervals along the rotor, and vent passageways connecting the radial ducts to the axial coolant passageways to enable cooling air to be forced through the coolant passageways and the vent apertures into the radial ducts and thence into the air gap of the machine when the rotor is assembled in operating position. The rotor of the invention is particularly characterized by incorporating radial cooling ducts that extend between each adjacent pair of conductor slots from the periphery of the rotor to points substantially below the bottoms of the conductor slots in the rotor laminae. All of the laminae are stacked in aligned position and compressed to form tight seals therebetween that prevent molten metal from flowing out of the conductor slots into the interstices between the respective laminations of the assembly during a rotor casting operation.

摘要： A laminated rotor for a dynamoelectric machine is formed by stacking a plurality of sets of punched laminae on one another to define axial coolant passageways, radial vents and coolant ducts and axial conductor-receiving slots through the assembled rotor. Each of the sets of laminae include a group of main rotor laminae, a group of vent laminae, a group of duct laminae and a transition lamina positioned between the vent laminae and duct laminae. In addition, a transition lamina is positioned between each set of stacked laminae thereby to arrange one transition lamina on opposite sides of each group of duct laminae, to effectively block molten metal from flowing out of the conductor slots into the coolant ducts of the duct laminae.
