Abstract

With the widespread adoption in the industry of variable frequency drives (VFD) for both small and large motor-inverter systems, rolling bearing showed a reduction of lifespan due to inverter-induced bearing currents [1]. Damages include generalized roughness due to pitting and fluting of the bearing races surfaces and rolling elements. These damages are directly related to current flowing between the bearing components and results in vibration, increased friction with associated heat generation and ultimately can lead to bearing seizure or catastrophic failure.
