Abstract
Systems, methods and computer program products calculate the life remaining in a machine, such as an electric motor, or the life remaining in individual components within a machine. Life remaining calculations are based on information collected from multiple sources, including operator input data, historical data, and lookup tables. Using this information the remaining useful life of the machine is calculated based on quantitative data, standard design life limits and on reliability analysis such that continuous historical parameter data is not required to analyze or assess the life of the machine.
Claims26
A machine life indicating system, comprising:
- means for receiving historical data, the historical data providing an indication of the operating lifetime of major components within machines of a particular type;
- means for calculating the life remaining in a machine using, the historical data and the L10 life calculation, wherein the L10 life calculation comprises the load factor rating and the rotational speed of the machine;
