Encoders for Wind Energy

Encoder products and motion control solutions for wind turbines

BEI Sensors rotary encoders provide reliable feedback for speed control, position and overspeed protection for wind energy applications worldwide. Wind turbines present a unique set of challenging environmental conditions. Extreme temperatures, electrostatic discharge, vibration, and exposure to hydraulic fluids can all shorten the life and performance of wind turbine components. BEI encoders are designed from the ground up specifically for these severe environments, and provide precise, reliable performance to assure maximum energy production.

BEI Sensors rotary encoders are ideal for gear train and generator speed control, pitch propeller position, and yaw axis position and speed control.
