Sensor Data Trending: Enertics analytics platform provides easy access to the motor health
historical data and analysis. The ongoing motor monitoring & diagnostics will allow Enertics to
identify vibration and temperature patterns that will be able to identify issues at an early stage.

Spectrum Analysis: Each simulated fault-mode provided a 3-axis Fast Fourier Transform
vibration signature, allowing the Enertics system to validate and correlate to the specific motor
faults.

" There's a significant cost advantage, as well, " he noted. Explaining that
often, laying cables for hardwire connections can be challenging in a heavy
industrial setting. " Now you are able to do all that using wireless
technologies. "

What is the primary advantage for users of Industrial motors?
" The primary advantage is, again, without a continuous monitoring and
diagnosis system, they are really in the dark. Even if they have a manual
planned maintenance program which calls for technicians or engineers to test
the machinery every month, or a week even - for some critical processes they
may be testing them every week - but that's still not a foolproof system, what
happens if there's an anomaly in the systems during the week? They wouldn't
have any visibility. "
" Having this kind of system in place, they are able to monitor continuously
and pinpoint the problem areas continuously - but more importantly, from the
predictability perspective, looking at the data analytics they can plan their
shutdowns, their maintenance activities, their service activities, etc. on an
actual basis. Extending the life of these critical assets but also optimize how
they shut them down. And of course, that's going to translate into the
significant savings for them.

Aside from vibrations, what other abnormal behaviours can the
sensors detect?
" We can detect temperature from various parts of the machine. For example,
on the drive-end bearing as well as the non-drive-end bearing, we can sense
the temperature change. We can also sense temperature from the stator
winding of the machine. A lot of times, when there is a fault situation, these
temperatures go up very quickly. What we do as part of our analysis is correlate
this information from the temperature and vibration sensors and we draw
conclusions based on that. "
" The vibration and temperature is good for smaller machines, to help
diagnose up to 98-99% of faults, however when we go to the mega-watt scale
machines, a lot of times there is a need to do additional analysis on the
electrical parameters, " as Sagoo mentions above, this is an instance where
Mohawk impacted the direction of their technology, " we have a technology
roadmap based on the testing and validation we did at Mohawk, " he said.
" At the end of the day we'll end up with a menu of options for the customers
to choose from. We'll have the physical parameters, temperature and
vibration; and the electrical parameters, and from there we'll be able to
provide a very detailed machine analysis. "
