iPresentation Tutorial discusses the fact that the Pulse-Width Modulated
motor drive (PWM) has different failure modes and for troubleshooting
purposes an electrician commonly uses a Digital Multi Meter (DMM),
digital oscilloscope and power quality analyzer. However, these
instruments are difficult to integrate into a Motor Reliability Testing
program. Electrical Signature Analysis (ESA) offers distinct advantages
over the DMM, oscilloscope, and power quality analyzer for Reliability
testing purposes. Moreover, besides evaluating the condition of the
incoming power and the motor drive, it will also evaluate the condition
of the motor and the driven load for many common failure modes. |
