Some motors require a speed feedback sensor mounted on the main shaft between other parts in the machinery. Here the shaft dimensions may be large, sometimes around a metre, which means that a standard optical encoder is not suitable. Therefore Leine & Linde has developed a series of bearing-less encoder rings, the 2000 series, with several features specially designed to meet the demands found in heavy industries.
One feature that makes the series ultra suitable for such applications is the tolerated air gap between the rotating ring and the fix scanning unit. In heavy duty applications the motor often handles heavy mechanics and may be exposed to powerful shocks and vibrations, something that will result in a certain runout of the shaft. With an accepted air gap of up to 2,6 mm the 2000 series offers excellent performance in these conditions.
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 and when performing service. With a segmented ring the pieces may be mounted from two sides of the shaft and screwed together.
Fixing the ring to the shaft can be made through flange mounting with axial screws or by a ClampFit solution for simplified commissioning. With ClampFit, the ring segments are screwed together in a way that automatically tightens around the mating shaft. This saves commissioning time and enables fixing to a standard cylindrical shaft without any flange expansion.
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, something that makes them extra suitable for installations in the process industry where very long cables may be needed in order to reach out to each encoder in the factory.
