Wind Turbine Business

Wind turbine technology continues to evolve at a constant pace.

NTN undertakes the manufacture of component technology that will facilitate the spread of environmentally-friendly wind turbines, by providing products that help realize “harmony with the natural environment,” “solve energy problems (global warming),” and “contribute to global society.”

Nacelle is the Core of the Wind Turbines

The nacelle is a box-shaped housing unit installed next to the turbine’s blade whose rotation is powered by the wind. Equipped inside the nacelle is a main shaft that enables the rotation of the blade; a gearbox which increases the rotation speed in order to generate electric power; a generator which converts the wind power to electrical power; and a yaw drive that changes the direction of the turbine in accordance with the direction of the wind. NTN bearings are employed in each one of these mechanisms.

Condition Monitoring System for Wind Turbines “Wind Doctor™”

Applying its bearing diagnostics technology, which has been cultivated by the company over many years, NTN has developed the Condition Monitoring System for Wind Turbines (CMS), which uses the world’s smallest data collection device (based on in-house research).
