Baumer sets new benchmark in absolute encoders

Like previous years, the SPS/IPC Drives exhibition in Nuremberg is the venue for Baumer to present their product innovations which this year are three absolute encoders which set new standards in technology.

Besides the latest generation of Ethernet-based encoders and product additions to their HeavyDuty encoder portfolio, Baumer also presented benchmarking efficiency in motor feedback encoders with high-precision optical sensing.

In the field of magnetic bearingless encoders, Baumer introduced two new product series for precise speed feedback, plus a compact magnetic encoder EMF500 for direct motor integration. This series is an alternative to conventional resolvers and underlines the Baumer competencies and expertise in motor feedback.

The platform architecture of new EAL 580 series represents benchmark fieldbus encoder design setting new standards in compactness and efficiency. A radial connector outlet and the shallowest installation depth at only 58mm, enable the encoders to fit very small installation spaces. The PROFINET product variant integrating Media Redundancy Protocol (MRP) will significantly improve machine and equipment productivity. Automated device configuration using the Link Layer Discovery Protocol (LLDP) will cut down on downtime during servicing since no programming tool is required for device exchange. The new absolute encoders support PROFINET with OPC UA standard compliance and are first on the market to be attributed “Industry 4.0 ready”.

At SPS/IPC Drives 2015, Baumer further extended their portfolio. The new generation of absolute HeavyDuty encoders is the merger of a sophisticated construction concept with bearings at each shaft end, new magnetic high-precision sensing and the patented Baumer Energy Harvesting technology which has proved its reliability with more than 10 years of HeavyDuty use. The outcome is the new benchmark in HeavyDuty encoder technology - even more robust, efficient and with a precision that so far only optical sensing could achieve.

With the latest generation of absolute HeavyDuty encoders, Baumer Hübner being the HeavyDuty competence centre of the Baumer Group has reached a new performance level to meet the highest requirements in demanding applications.

In the field of motor feedback, Baumer presents a new series of efficient encoders in 36 and 58mm design with ultra-accurate optical sensing. Thanks to high-precision mechanics and precise alignment of the sensing unit, the EFL360 and EFL580 series with BiSS interface supply high-precision signals down to the micrometer range while featuring resolutions of up to two million steps per revolution. Both series operate on a highly optimised Opto-ASIC merging all basic optical encoder functions in a single component. Besides cutting down on component cost, the encoder is less prone to errors and more resistant against mechanical impacts such as strong shocks or vibrations.

Also premiering at SPS in bearingless magnetic encoders are series ITD89H00 and MQR69 with high-performance signal processing for precise speed acquisition. Series MQR69 excels with resolutions up to 24 bits per turn, efficient noise filtering and by supplying a digital speed word in addition to the position information via RS485 interface. Optimally harmonised component design and manufacture ensure precision signals for trouble-free continuous operation.

Compact motor feedback absolute encoders EMF 500 are another product highlight. These bearingless magnetic encoders are a powerful alternative to conventional resolver technology. With single-turn resolutions up to 22 bits and digital signal transmission these encoders contribute a significant share in keeping up with the ever-growing requirements on efficiency and control quality at speed-controlled drives. The EFM500 encoders close the gap between resolver technology with limited signal quality and high-resolution absolute encoders of superior price classes.
