Preventative vs. Predictive Motor Maintenance: Which Is Right for You?

Blog

Downtime from a faulty or burned out electric motor can create unnecessary work.

No matter the type of equipment the motor powers, when electric motors fail productivity plummets and frustration grows. Non-efficient motors consume a great deal of daily energy demands, including:Preventative vs. Predictive Motor Maintenance

  • – 78% of all electrical energy in industrial processes
  • – 43% in commercial buildings

While some electric motors fail with no warning, the majority of failures come about due to a lack of a proper maintenance program. Unfortunately, many companies still stick by a “run to failure” maintenance strategy. That is exactly what it sounds like: run motors into the ground and just replace them.

It is not the greatest idea in the world, because it kills productivity and can create expensive repairs. When it comes to electric motors, most experts agree that you have two real options: preventative or predictive motor maintenance.

Preventative Motor Maintenance (PM) is either time-based or schedule-based. This forces maintenance checks regardless of the actual condition of the equipment. This type of maintenance is an effective way to guarantee the dependable and long-life operation of electric motors. The major downside has to be the set costs, which can eat into your bottom line. You will end up spending the same amount every year whether the equipment needs the maintenance or not.

Predictive or condition based Motor Maintenance (PdM) is where machines are measured with objective machine monitored trending methods. One immediate benefit of PdM is that you end up avoiding unnecessary repair costs and downtime. These non-intrusive testing techniques rely on proven scientific methodologies to predict the condition and lifespan of your electric motors.

Some of these high-tech methods include:

  • – Vibration Analysis
  • – Infrared Analysis
  • – Motor Drive Alignment
  • – Winding Analysis
  • – Onsite Balancing
  • – Oil Analysis

You can combine all of these methods into one PdM that will instantly increase your ability to avoid major electric engine breakdowns and incidences. It is a perfect example of how common sense and high-tech equipment come together to save you tons of time and money.
