A jet of compressed air should be used to remove non-abrasive dust from the fan cover and any accumulated grime from the fan and cooling fins. Soft brushes or clean cotton rags should be used for cleaning.

Motors should be kept clean, free of dust, debris and oil. Incorrect or no lubricant, (too old lubricant, wrong amount of lubricant, dirt in lubrication etc ).The major reasons for premature bearing failure are // The calculations do not take the effect of adverse operating conditions into account.īearings in standard motors are always lubricated with grease either once and for all (greased-for-life) or they may be relubricated via lubrication nipples. Actually, only a small amount of bearings reach their optimum lifespan. The explanation is linked to maintenance. To make these calculations it is essential that the bearings are mounted and lubricated correctly. It is possible to calculate the lifespan of bearings based on the material fatigue if we know the motor’s operating load and speed. The lifespan of the bearing varies between 16,000 – 40,000 hours or more.Īs to the lifespan of the grease it is normally at least 40,000 hours under normal operating conditions. When, depends on either the lifespan of the bearings (L 10h) or on the lifespan of the grease that is used as lubrication (F 10h). Greased-for-life bearings or maintenance-free bearings have to be replaced eventually. They do not imply that the bearings do not need maintenance at all. Some bearings are referred to as greased-for-life bearings or maintenance free bearings. Only about 1% of all rolling bearings reach expected life.

Therefore, when carrying out preventive maintenance on the motor, replacement and maintenance of bearings are indeed important factors!! Causes of failure in rolling bearings. The Thermo Scientific Technical Support team has developed Instrument Verification Sheets that allow you to track preventative maintenance and audit verification activities to ensure the positioning of your monitor or sampler for optimum performance. The most common error is no longer short circuit but noise from the bearings and bearing damage. The reason is that the insulation system is no longer subject to high temperatures because the efficiency of motors has improved over the years.

With a preventive maintenance program with MAC Door Solutions in place, you wont have to rely on luck. Today, bearings are the components in the motor that are most exposed to wear. Preventive Maintenance It is better to be prepared than to be lucky By having your doors maintained by MAC Door Solutions, you can be sure that the doors will be in working condition, saving you unnecessary troubles and costly repairs. The major causes of motor failure, according to the Electrical Research Association, USA That is a short-circuit between the phases or between the phases and the frame. Usually, induction motors are capable of handling overvoltage situations. However, severe overvoltage may cause turn-to- turn, phase-to-phase or phase-to-ground short circuiting. At lower voltages, motors run at a reduced full-load efficiency, run hotter, have a larger slip, produce less torque, and may have a shorter lifespan.
