Abstract: Stators for use in electric machines and methods for refurbishing the same. One method for refurbishing a stator for use in an electric machine includes at least partially disassembling the stator to provide access to a plurality of stator windings connected in a four-circuit star connection having three turns per coil, and reconfiguring the stator such that the plurality of stator windings are connected in a four-circuit delta connection having five turns per coil.

Abstract: An assembly tool (104) for positioning the rolling elements (150, 155) of a bearing assembly (100) during a preloading operation includes a roller seating actuator (400) configured to be removably coupled to a portion of the bearing assembly during the preloading operation, and a roller seating ring (420) movably coupled to the roller seating actuator. The roller seating ring includes a distal end (440) configured to engage an end of a rolling element of the bearing assembly. A biasing member (460) is positioned between the roller seating actuator and the roller seating ring and biases the roller seating ring away from roller seating actuator such that the distal end of the roller seating ring engages and presses the rolling element axially into engagement with a rib (145) of a race of the bearing assembly.

CPC classification number: H02K15/028 , H02K1/185
Abstract: A refurbished rotor of a wound rotor machine. The refurbished rotor includes a plurality of windings assembled to the rotor core, each manufactured from two separate bars: a top coil and a bottom coil. The top coil is positioned in a rotor core slot at a position radially outward of a position of the bottom coil within another rotor core slot. Each top coil and each bottom coil has a flat rectangular cross-section. On a connection end of the rotor where rotor leads are attached, the top coil has a flat end positioned alongside and in alignment with a flat end of the bottom coil of an adjacent one of the plurality of windings. The top coil and the bottom coil have respective flat ends joined to each other on a non-connection end of the rotor opposite the connection end by a joint for establishing electrical continuity.

Abstract: A rotor of a wound rotor motor/generator comprising a plurality of rotor windings including a line rotor coil and a star rotor coil. The rotor coil couples to an L-conductor having an L-shaped profile such that a portion of the L-conductor extends from the line rotor coil toward the star rotor coil. A line connector bar couples the L-conductor to a rotor lead such that the line rotor coil is electrically coupled to the rotor lead. The star rotor coil couples to an L-support having an L-shaped profile such that a portion of the L-support extends from the star rotor coil toward the line rotor coil. An insulator is positioned between the L-conductor and the L-support to electrically insulate the L-support from the L-conductor. Lastly, an insulating rope couples the L-conductor to the L-support.

Abstract: A roller bearing includes an inner race ring, an outer race ring, and a roller arranged between and in contact with the inner and outer rings. The bearing has a flange on the inner race ring at one axial end, and a flange on the outer race ring at an opposite axial end. At least one of the flanges, or an end of the roller, has a profile including a principal segment with a reference point C defining a contact location between the roller and the flange, the principal segment having a continuously changing radius of curvature, on both sides of reference point C, that decreases as a distance from the reference point C increases.

Abstract: A system and method for determining a position and or speed of a rotating shaft includes a target wheel for securement to a rotatable shaft, the target wheel including a plurality of North/South pole pairs, each pole of each North/South pole pairs being essentially the same size; and a sensor assembly. The sensor assembly includes a first magnetic sensor array for sensing the pole pairs to provide a cosine signal and a sine signal and a second magnetic sensor array for sensing the pole pairs to provide a cosine signal and a sine signal, wherein the second magnetic sensor array is disposed transverse to the first magnetic sensor array. An electronic processor is configured to receive inputs from the first magnetic sensor array and the second magnetic sensor array, and to determine a position and/or speed of the shaft.

Abstract: A thrust bearing includes a first axial end washer defining thereon a first race, a second axial end washer defining thereon a second race, a one-piece, radially-inner washer having a first axial end engaged with the first axial end washer and having a second axial end defining thereon a third race, and a one-piece, radially-outer washer having a first axial end defining thereon a fourth race and having a second axial end engaged with the second axial end washer. A first set of tapered rolling elements is supported between the first race and the fourth race and a second set of tapered rolling elements is supported between the second race and the third race. The first and second sets of tapered rolling elements are both axially and radially offset from one another.

Abstract: A bearing assembly includes a split inner race ring configured to be installed on a shaft and defines two raceways for supporting rolling elements. A split clamping band is configured to be installed over the split inner race ring to secure the split inner race ring on the shaft. A split seal wear ring is configured to be installed on an outer diameter surface of the split clamping band. An engagement interface between the split clamping band and the split seal wear ring includes a boss on one of the split clamping band and the split seal wear ring, and an aperture on the other one of the split clamping band and the split seal wear ring. The aperture is sized and configured to receive the boss for positioning the split seal wear ring on the split clamping band.
