Learn how to protect the electric motors that drive your pump systems from electrical current damage.

While Variable Frequency Drive (VFD) systems are an exceptional tool for improving electric motor-driven system efficiencies, they also create conditions in the controlled motor that can cause electrical arcing inside the device’s bearing. Ultimately, this can lead to premature bearing failure.

This paper presents several different approaches that can be used to protect bearings from damage, including the advantages offered by ceramic materials, a coated bearing or a hybrid bearing – each of which can provide a cost-effective solution for new or rebuilt applications. Considering the high cost of unscheduled motor bearing failure, providing some form of protection is always a sound investment.

Which makes having a look at “Protecting E-Motor Bearings from Electrical Current Damage” well worth a few minutes of your valuable time!
