For the SPS IPC Drives 2016, HEIDENHAIN is supplementing its existing program of inductive position encoders with its new rotary encoder series ECI 4000/EBI 4000. The new variants are modular devices without integral bearing and with a 90 mm hollow shaft. They enable you to replace the conventional toothed-belt drive for coupling a motor feedback system to torque motors. With fewer components, the new rotary encoders provide increased performance and guaranteed wear-free operation. Moreover, they set new standards in attainable control dynamics, reliability and functionality. In this way they open up new applications for inductive rotary encoders, e.g. on highly dynamic motors, drive modules and machine components that require a corresponding hollow shaft in the encoder.
