Condition monitoring during operation
Supervising the electric machine correctly during the operation ensures reliable operation and designed lifetime.
If you notice any deviations from the normal operation, for example elevated temperatures, noise or vibration, stop the
electric machine. Find the reason for the deviation and repair the electric machine. Refer to Chapter 9 Troubleshooting.
Maximum temperature of the bearings of the electric machine is:
120°C.
The maximum allowed winding temperature of the electric machine is shown in the rating plate and in the data sheet.
Recommended lubricants
Greased for life bearings do not need relubrication during their lifetime. Grease relubricable
bearings (BHS option) need regular greasing. See Chapter Maintenance - Bearings and
lubrication for further information.
The recommended grease type for the machine bearings is SKF LGHP-2 or equivalent. LGHP-2 is
high performance, high temperature bearing grease. For further information, see
http://www.skf.com/
Recommended coolants
Use correct personal protective equipment when you handle the coolant.
Ethylene glycol is a toxic compound. Avoid exposure to the coolant.
Other options:
Propylene glycol based coolants, like Splash® RV&Marine antifreeze.
Ethylene glycol based Glysantin® G48® (includes also corrosion inhibitors).
