INTORQ BFK series brakes are used by several wind turbine manufacturers with torques from 14 to 200Nm. These brakes are often customised but are always single disc design with multiple engagement springs and DC coil release. They are mounted onto the back of the motors; servo motors for the pitch drives and standard asynchronous motors for the azimuth drives of which there are typically four or five on a wind turbine. They are designed for 100 per cent running time with coil engaged and the rated torque can be applied with either dynamic or static brake engagement.
Wind turbines present some of the most challenging conditions for industrial brakes, and the need for reliability and low maintenance is evident. INTORQ brakes are developed to meet these challenges as can be seen from B10d lifetime ratings of up to 20 million hours.
