ABSTRACT:
A motor performance analyzer senses currents and voltages applied to the motor, converts the sensed signals to digital data signals, and stores the digital data signals. The analyzer includes a processor for evaluating the digital data and a display for alerting a user or technician to potential winding faults. Advanced signal processing techniques are used to further evaluate stored data and to provide trending information.
