Time to Failure Estimation with ESA Series Part 1 Electric Motor Theory

Archive, Electrical and Current Signature Analysis, Electrical Reliability, EMPATH, Energy, Motor Diagnostics, Motor Theory, Physical Asset Management, Reliability

As we start into ESA theories and application, we will have to spend a little time on electric motor theory.  As we will start out with a basic system, AC motors are the simplest in terms of operation and components, we will start out with AC induction motors.  Using this base knowledge, we can later…

Insulation Death Due to Old Age

Electrical Reliability, Insulation Systems, Motor Diagnostics, Motor Repair, Motor Theory, Physical Asset Management, Reliability, Time To Failure Estimation TTFE

It does happen, although rarely, in typical industrial environments that an electric machine will die of old age.  The reason is that machines are often exposed to contamination issues, other environmental issues, power issues or a combination of events that degrade the insulation slowly or rapidly. There is also a rule of reliability that should…
