The main maintenance problem with the current forms of wind generator comes from gearbox failures. Technical research has shown that it is the complex interaction between components of the gearbox that causes the vibrations during normal operating conditions. This is the source of most component failures with 80% of gearbox failures being faults with the bearings.
Wind generator companies have now turned to direct drive systems for a solution; Elimination of the gearbox means a more reliable system. Direct drives without a gearbox could be used to generate a smoother, wider power output range.
ePropelled’s magnetic gearing can:
- Increase the efficiency of energy extraction
- Be used to design a new drive train by eliminating the gearbox
- Minimizes the number of moving parts
