FoxYaw and pitch controlfor wind turbines
The rotary limit switch Fox is used to control the position of the nacelle or the pitch angle of the blades of a wind turbine.The motor that controls the rotation of a wind turbine on the yaw axis (or of the blade around its longitudinal axis) transfers the movement to the limit switch. A rotary encoder reads the rotation of the shaft, and its pulses are sent to a PLC which controls the position of the nacelle or of the blade. The movement of the shaft is also transferred, through a gearmotor, to a series of cam switches: the appropriate setting of the actuating point of the cams can signal up to four critical positions of the movement of the nacelle or of the blade.Fox features transmission and gear driving shafts made of high resistance stainless steel, worm gear transmission shaft rotating on ball bearings, self-lubricating techno-polymer gears and driving bushes, techno-polymer base and cover. All techno-polymers used for the enclosure are wear resistant and protect the equipment against water and dust.
Fox is available either for horizontal mounting (worm gear shaft parallel to the fixing base) or for vertical mounting (worm gear shaft perpendicular to the fixing base).Revolution ratios result from the combination of different secondary output steps. Fox can be fitted with different combinations of actuators and motion detectors: sets of cams and microswitches (max. 4), potentiometers or encoders (max. 2), encoder for set of cams and microswitches (max. 1). Furthermore, there is a special seat for the integrated assembly of a boxed electronic card (Fox HF) used for the worm gear shaft movement detection and for managing all other actuators and motion detectors. It is possible to fit together sets of cams and microswitches, potentiometers, encoder and electronic integrated card, thus creating a safety device featuring redundancy and diversity. The limit switch can be customized with labels and colors.
