A Better Understanding of a Non-VFD Rated Motor and the Thermal Effects When Used with a VFD
T he motor in question for this case study was on a VariableFrequencyDrive(VFD)butwasnotVFDrated. While on my infrared mechanical route I found thisparticular motor running hot. The surface of the motorappeared to be approximately 58°C (136°F) while the sur-roundingmotorswereshowing10°C(50°F).Thetemperatureoutsidewas4°C(25°F)with2to3mphwinds.

In 1986, the Electric Power Re-search Institute (EPRI) funded Gener-al Electric to conduct a study for thecausesofmotorfailures.Ofthemotorfailuresmonitored,36%ofthefailureswere Stator related and an additional10% were attributed to Rotor failures.The majority of other failures weremechanically related. Looking at thebasicstatistics,47%ofthefailureswereelectricallyrelated.However,nostudywasperformed todetermine ifanyofthe mechanical failures were electri-callyinduced.

Developing a list of critical equipment shouldbe apartofthisprocess.l Equipment: If you have a condition monitoring program you should evaluate the thermal imagingequipmentyouarecurrent- ly using and determine if it still meetsyourinspectionneeds.Ifyou aredevelopingaprogramthenyou must first determine what types of inspectionsyouaregoing todo and then determine which camera has the capabilities you need to performthoseinspections.
l Safety Practices: Personnel safe- ty should be a primary concern of any reliability-centered mainte- nance (RCM) program. When fol- lowing industry best practices you should use NFPA 70E as one of yourguidelines.
l Routes and Scheduling: Knowing what you want to inspect and developing efficient routes and schedules for conduct- ing the inspections in a realistic time frame given available personnel resources will be critical toyoursuccess.
l Inspection Procedures: Once you have your list of equipment inspection list, routes, and scheduling done you must then develop inspection procedures for the different types of equipment tobeinspected. l Reporting: An important part of any condition monitoring program is reporting. Reports must be detailed enough so that mainte- nance technicians can identify what repairs need to be made to eachasset.l Training and Certification: If your program follows or will follow American Society for Non DestructiveTesting(ASNT)guide-
lines,thentrainingandcertification isveryimportant.Undertheseguide- linesthegoalofanyprogramshould be toget IR technicians toLevel II standards in an efficient manner through quality training programs andplentyoffieldworkandhands- oncameratime.l Performance and Metrics: No program is complete unless measures of success are clearly defined.

Will it have to be integrated into your CMMS? Don’t forget that after the newness has worn off a certain amount of self promotion will be necessary to keep the results and benefits well knownwithinyourorganization.lContinuous Improvement: Finally, continuous improvement should always be a goal of any effective condition monitoring program.
