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 method for predicting mechanical failure of a traction motor in a vehicle includes monitoring first characteristics of an electrical signal supplied to a traction motor of a vehicle during a first detection window. The first characteristics represent a first motor electrical signature for the traction motor. The method also includes deriving one or more signature values from a first mathematical model of the first motor electrical signature and predicting a mechanical failure of the traction motor based on the one or more signature values.
