摘要： What is disclosed is a novel system and method for determining real-time performance in a sub-assembly device that is driven by a dc motor. In one example embodiment, an electric motor is energized such that a sub-assembly driven by the motor achieves a target operating speed. Pulse width modulation data is captured and plotted along a time axis. A time duration when the sub-assembly device ended a startup operation and achieved a steady state operation is determined. A portion of the plotted data is then compared to an ideal plot defined for that sub-assembly device. Based on the result of that comparison, a determination is made whether the sub-assembly device is performing within accepted operational parameters. A maintenance operation is signaled to be performed in response to the determined sub-assembly operational performance. The data is stored in a historical database from which a preventative maintenance schedule can be derived.
