Plant Air Wash Supply Fan EXAMPLE High Temp = ____ How to Ambient = ____ perform Temperature Rise = ____ in-house infrared trending of Electric Motors Example Report EXAMPLE SURVEY OF ELECTRIC MOTORS

High Temp Procedure for trending temperatures on Electric Motors Plant EXAMPLE • Make sure the motor is at operating temperature (steady-state). Air Wash = ____ Ambient = ____ Temperature Rise = ____ • The first time the survey is performed, take a photograph of the motor. Take a thermograph Supply Fan (infrared picture) also, if you have an infrared (IR) camera. But you do not need an IR camera for this. If you have one - use it, but a $100 spot radiometer will do just fine. • Take a can of barbeque grill paint (E=~. 95), SAFELY clean and/or paint the points where you plan on taking the temperatures. • Enter the date. • Enter the high temperature (HT). Get the high temperature from the inboard bearing. • Enter the ambient temperature (AT). Get the ambient temperature from the motor foot or a painted spot on the floor near the motor. • The Temperature Rise (Delta-T) will automatically show in the spreadsheet and on the graph. • Put this page in a notebook (or the spreadsheet below) and take the notebook to enter the numbers each month/week/day. • If the trend is higher temperatures every time you check the motor: § Increase the frequency (say from monthly to weekly) and see if the Delta-T continues to rise and watch it closer. § Check other connected components, i. e. , outboard bearing, winding, coupling. § Add other testing, i. e. airborne ultrasonic analysis, vibration analysis, oil and wear particle analysis, eddy current analysis. General Notes: Ø Pick a temperature scale at the beginning of the trending. (Either °C - Celsius or °F - Fahrenheit and always use the same scale. Ø Keep the surface clean with an air hose, so dust does not build up on the inboard bearing and insulate it. Ø After blowing it off, give the bearing a few minutes to come back to steady state temperature. Ø This trending is predicated on the fact that the Delta-T (HT - AT = Delta-T) will not change if the motor stays in the same condition. Ø If the motor's inboard bearing gets hotter over time, something is wrong. Increase frequency and check other components. Ø The motor's inboard bearing is the pivot point of all other connected components, if something goes wrong anywhere, the bearing heats. Ø Don’t worry about being off a few degrees here or there. The idea is that you will be able to see a trend. Even if some errors are introduced, so as long as you use the same repeatable method, you will see the trend. EXAMPLE SURVEY OF ELECTRIC MOTORS
