Magnetic ring encoder – speed feedback for large shafts in The Windfair Newsletter

The Leine & Linde ring is segmented into pieces, something that facilitates commissioning and service. As the ring is often mounted on a shaft between other parts in the machinery it may be difficult to access it, both when first mounting it and when performing service. With a segmented ring the pieces may be mounted from two sides of the shaft and screwed together. The segments also make handling easier when transporting and storing the ring.

Fixing the ring to the shaft can be made through flange mounting with axial screws or by Leine & Linde’s ClampFit solution for simplified commissioning. With ClampFit the ring segments are screwed together in a way that automatically tightens the ring around the mating shaft. This saves commissioning time and enables fixing to a standard cylindrical shaft without any flange expansion prepared.

The speed pickup unit is available with several market standard interfaces for incremental signals. The interfaces High Current HTL and Optolink have been specially designed for long distance transmission, which makes them extra suitable for turbine designs where the encoder signals need to be transferred from the top of the tower down to the ground.
