MR200W series Yaw Position Transducers monitor yaw, direction, speed, and cable twist while providing feedback to the wind turbine’s yaw directional motor drive and brakes. The units, from Micronor Inc, Newbury Park, Calif

Depending on performance requirements, functions, and quantities, an integrated OEM solution of the Micronor MR200W can cost from $1,000 to $2,000.

, can be multifunctional and work with any combination of electromechanical limit switches, rotary encoders, resolvers, or potentiometers. Anti-backlash POM (polymer) pinion gear optimizes coupling to the turbine’s large yaw bull gear for long term reliability, accuracy and repeatability.
The device, engineered for wind turbines, monitors position, direction, speed and cable twist while providing feedback to the yaw-motor drive and brake controls. An MR200W series position transducer can be multifunctional and built into any combination of geared limit switches, rotary encoders, resolvers, or potentiometers. For increased accuracy and repeatability, the unit can be supplied with an external anti-backlash POM (polymer) pinion gear which optimizes coupling to the wind turbine’s large yaw bull gear.
