Renewable Energy: Micro Wind Turbine
History
A micro wind turbine project was in danger of being shut down due to the prohibitive cost of the bearings being used. For the project to continue, purchasing and manufacturing costs needed to be reduced.
Corrective Measures
A visit by an NSK engineer established that the machine design needed to be reviewed to significantly reduce the unit build cost. By reviewing the complete unit build, we managed to save around 337.600 Euro to our customer. Additional advantages: improved performance, increased reliability, simplified assembly procedures and longer bearing life (up from 200,000 hrs to 224,400 hrs).
