# Wind Turbine Generator Bearings: Requirements & Solutions

## Generator

The wind turbine generator converts mechanical energy into electrical energy. It operates at high speeds and is exposed to stray currents, which creates specific requirements for bearings.

## Operating Features

- High rotational speed (1000-1500 rpm)
- Exposure to stray currents
- Heat generation from electromagnetic losses
- Vibrations from the rotor

## Solutions

Bearings with electrical insulation are used: either ceramic coating or ceramic rollers. Angular contact ball bearings and cylindrical roller bearings are employed. The use of bearings with current-collecting rings is recommended.
