摘要： A high-altitude railroad locomotive adapted for more reliable operation at high altitudes, wherein the high-altitude railroad locomotive includes a semiconductor electric power control component, and wherein due to the high altitude the locomotive would be exposed to high levels of cosmic radiation tending to damage the semiconductor electric power control component is provided. The high-altitude locomotive includes electric power generation equipment, a plurality of traction motors mechanically connected to wheels supporting the high altitude locomotive and an electric power transmission system for transmitting electrical power from the electric power generation equipment to the plurality of traction motors. A DC bus is also included and electrically connected to the traction motors and a power controller for controlling the transmission of power over the DC bus, the traction motors having a second active motor volume, wherein the second active motor volume is larger than the first active motor volume to enable the DC bus voltage of the high-altitude locomotive to be reduced relative to the first DC bus voltage while generating a range of mechanical power sufficient to propel the locomotive at high altitudes, whereby the combined effects on the semiconductor electric power control component caused by the DC bus voltage of the high-altitude locomotive and by the cosmic radiation correspond to these effects on the semiconductor electric power control components of the low-altitude locomotive when operating at low altitudes to reduce the likelihood of failure of the semiconductor electric power control component of the high-altitude locomotive.

摘要： A direct current machine monitoring system includes a current sensor for monitoring load current of the machine; and a computer for obtaining a power spectrum in a range including a machine trait-passing frequency, determining a magnitude of a maximum peak in the power spectrum in a range including the trait-passing frequency plus or minus an uncertainty frequency, and evaluating the magnitude of the maximum peak to assess a condition of the machine. The computer may additionally or alternatively be used for obtaining a low frequency power spectrum of the load current, obtaining at least one magnitude of a component of the power spectrum at a respective predicted frequency, and evaluating the at least one magnitude of the component to assess the condition of the machine.

摘要： A segmented stator end turn air deflector for an electric motor having a stator and a rotor. The stator has a plurality of stator coils with end turns and a plurality of air passages extending longitudinally through the stator. A frame having an inlet end and an outlet end surrounds the stator. The rotor is rotatably mounted inside the stator and the frame. Brackets are coupled adjacent to the outlet end of the frame in a circular orientation. An air baffle assembly is coupled with respect to the stator adjacent to the outlet end and extending between, but out of contact with, the frame and ends of the coils for the purpose of directing any air flowing from the air passages onto the end turns. The air baffle assembly includes a plurality of arcuate segments each coupled to a respective one of the brackets. The air baffle assembly further has a radially interior arcuate end and a radially exterior arcuate end and angularly oriented side edges which converge inwardly.
