New encoder intended to facilitate compact servomotors

Hengstler’s new Acuro AM34 absolute encoder is intended to facilitate very compact servomotors. Hengstler is a European manufacturer of industrial metering and control components for automation.

The installation space in automation technology applications is becoming increasingly cramped. This poses great challenges for drive technology manufacturers since industry was constantly calling for more compact motors, Hengstler explained.

The new Acuro AM34 absolute encoder from Hengstler meant this was no longer a problem. "The installation depth of the high-precision encoder is less than 20 mm and as a result makes it possible to design very small servomotors."

According to Hengstler, the positioning accuracy of ± 120 angular seconds made the Acuro absolute encoder suitable for use in servodrives. In addition, the encoder was bearingless and therefore produced hardly any heat of its own. Consequently, servomotors with these encoders could be operated at the highest speeds.

Quick installation

In the single-turn version the resolution of the Acuro AM34 was 16 to 20 bits and in the multi-turn version 12 bits. The working temperature range of the absolute encoder ranged from –40 to +120 °C.

The Acuro AM34 is designed for speeds of up to 12,000 min-1 and features a BiSS-/SSI interface for digital automation. Moreover, since the encoder had an electronic data sheet (EDS), users could install the servomotors very quickly. For drive technology manufacturers, integration in their motors was also very simple thanks to the great installation tolerances (±0.5 mm axial, ±0.1 mm radial), the produce emphasised.
