Wrong Technologies or Ineffective Technology

This is the continuation of the ‘Why Technology is Ineffective’ part of the Cost of Maintenance.

The Cost of Maintenance 2

Overview

We are going to take a number of the issues developed in the last Blog one step at a time.  This week, we are going to focus on the reason why technology has been ineffective in many motor management programs.

The Cost of Maintenance 1

We are going to change direction for a little bit.  The reason has to do with an area I wish to explore that starts with a ‘From the Editor’ article that I put in my latest email newsletter.  My plan is to continue following this track to its conclusion.  In this first installment I will re-present the article:

13 Motor Testing and CBM

In the early 1980’s, it was realized that voltage and current test results could be utilized in a different manner.  By using the electric motor, itself, as a transducer, the voltage and current waveforms could be evaluated by viewing the spectra resulting from an FFT (fast-fourier transform) of the sigantures.  Evaluation is performed by obtaining voltage and current data using voltage probes and current transformers digitized and evaluated.
