Bearing and gearbox failures: Challenge to wind - STLE

A wind turbine creates electricity when wind flows across the turbine blade and spins the rotor. The rotor is connected to a generator directly in a direct drive turbine or through a shaft and a series of gears (i.e., a gearbox) that speed up the rotation and allow for a physically smaller generator (see Figure 1). 15 This translation of aerodynamic force to rotation of a generator …

The purpose of insulated bearing for Motors with VFD

Dec 09, 2015· The purpose of insulated bearing for Motors with VFD drives or the Alternators is to prevent the flow of circulating current in a closed circuit through bearing and ground (if bearing is not insulated) and consequently prevent the bearing from damage. This circulating current is caused by induced voltage in the shaft because of AC flux.
