2000 Bearingless

Magnetic encoders for large shafts.

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 meter – which means that a standard optical encoder is not suitable. Therefore Leine & Linde has developed a new series of bearing-less encoder rings, the 2000 series. It is based on a concept of a rotating ring together with a fix scanning unit for generation of incremental pulses.
