Find out why motor analysis should be part of your maintenance routine

Acutest and FLUKE are hosting a free workshop here in Stoke on the 19th of September and you're invited: Troubleshooting Motors & Motor Drives

Not sure if motor analysis is important to your business, keep reading below!...

Electric motors are the workhorses of the industrial world accounting for up to 70% of the total energy consumed in an industrial plant. Given their critical nature for industrial processes, the cost of downtime associated with failed motors can be enourmous.

Ensuring that motors are efficient and operate reliably is one of the most important tasks that maintenance technicians and engineers face daily.
But troubleshooting and maintenance of electric motors can prove to be a challenge, requiring system shutdowns which is exactly what you need to avoid. Measuring and analysing motor efficiency including power quality characteristics are important to assessing performance of rotating equipment, as well as setting up an effective maintenance program.

Electric motors transfer electrical power to mechanical rotational forces that are the muscle of the industrial world. Measuring and analysing those forces—mechanical power, torque and speed—as well as power quality characteristics are important to assessing performance of rotating equipment. These measurements can not only help predict failure and thus help avert downtime, they can also help quickly determine whether additional inspections, such as vibration testing, shaft alignment analysis or insulation testing, are needed to corroborate the findings.

Traditionally, obtaining accurate motor analysis data required costly equipment shutdowns to allow for the installation of mechanical sensors. Not only can it be extremely difficult (and sometimes impossible) to properly install mechanical sensors, the sensors themselves are often cost prohibitive and introduce variables that decrease overall system efficiency.

Modern motor analysis tools make it easier than ever to troubleshoot electric motors by significantly simplifying the process and reducing the number of components and tools necessary to make critical maintenance decisions. For instance, the new FLUKE 438-II Power Quality and Motor Analyser enables technicians to discover electrical and mechanical performance of electric motors, and evaluate power quality by measuring the three-phase input to the motor, without mechanical sensors.

  1. Poor power quality has a direct correlation with motor performance
  2. The impact of torque on overall performance and efficiency
  3. Motor rating data and expected performance
  4. Motor efficiency has a direct impact on the bottom line
