摘要： A diagnostic technique for monitoring shaft cracking or incipient pinion slip involves monitoring a shift in a characteristic natural frequency of an operating system such as a geared system of a locomotive. The technique involves monitoring a shift in the characteristic natural frequency or resonance of a shaft for detecting shaft cracking. The technique also involves monitoring a shift in the characteristic natural frequency of one or more assemblies of the operating system which include a pinion and detecting a shift in the one or more characteristic natural frequencies of the assemblies. A vibration sensor or measurement of current changes of a motor of the operating system can be used to detect vibrations to monitor the characteristic natural frequencies. Torsional oscillations or measurement of current and voltage changes of a motor of the operating system, can also be used to monitor the characteristic natural frequencies.

摘要： High-permeability, low-core-loss soft magnetic composite materials, compositions containing the same, and methods for making the same are described. These magnetic materials are made by forming fiber or flake shaped particles from a ferromagnetic material, annealing the particles, and then coating an insulating material on the particles. These particles can then be compacted to form an article that has high permeability, high saturation, low core loss, and is a suitable replacement for laminations in various applications, such as motors.

摘要： A power generator that operates at a reduced keybar voltages and currents, flange currents, and keybar voltage differentials includes a keybar shield that reduces the amount of magnetic flux coupling into a keybar of multiple keybars during operation of the generator. By reducing the amount of coupled flux, the keybar shield reduces a keybar voltage and a keybar current in a keybar, reduces keybar current flowing into a flange, and reduces a voltage differential between voltages induced by the flux in the multiple keybars.

摘要： A sensing coil affixed to the outside of an induction motor housing uses flux signals from the motor to measure motor speed. In particular, components of the rotor current are measured and compared to analysis from stator fundamentals and sidebands to determine the true rotor frequency which can then be used to determine the motor speed. A shield and/or a compensating coil can optionally be used to filter out extraneous signal noise.

摘要： A multipole brushless DC motor stator is formed with a pair of complementary opposable claw pole stator structures in which each of the stator structures comprises a stator base formed of a plurality of stacked sheet metal laminations. A plurality of stator pole members extend from the stator base and are formed by compression molding of a ferromagnetic material. In one form, the ferromagnetic material is molded in situ on the stator base by positioning the stator base in a compression mold having the slots in which a powdered or flaked ferromagnetic material can be positioned and compressed by a die. In another form, the ferromagnetic pole members may be independently compression molded of powdered or flaked ferromagnetic material and then adhesively bonded to the stacked laminations forming the stator base. In either method, the stacked laminations are formed with a plurality of receptacles for receiving one end of each of the stator poles and holding the stator poles to the stator base.
