GMP Friction Products, working with wind turbine manufacturers and the suppliers to the OEM market, has developed high-speed friction brake materials designed to reduce rotational speed below maximum value or bring the blades of a wind energy turbine to a standstill.
Following more than 1,000 braking sequence tests, they have developed friction parts for brakes designed to more efficiently and reliably stop the wind turbine blades in the case of emergency or for maintenance. A high energy test, developed specifically for the wind market, has been successfully conducted using both the GMP Friction Products’ in-house dynamometers and third party dynamometers for equivalent energy, torque output, coefficient of friction, and wear rate. Field testing was also conducted using the new brake material. The tests were developed and conducted in collaboration with wind turbine manufacturers and brake manufacturers.
