Absolute feedback systems for efficient drives

Written by: Tom Austin-Morgan | Published:

The BML series from Balluff is said to offer rugged, precise and quick absolute position and angle measurements, suitable for installation or direct integration into drive and positioning systems.

The magnetically encoded absolute position and angle measurement systems feature IP67 housing for external installation. As an open kit for full integration, they have the option of being used in rotary applications. Balluff claims that by using these systems, the formats, strokes and end positions of axes can be adjusted automatically, quickly and reliably.

The absolute encoder disk can be integrated into motors and actuators as a precise, absolute feedback solution, which is an alternative to conventional magnetic or optical solutions for control of motors and drives. The device measures 12 to 20mm, depending on the design in length and 30mm in diameter.

An integrated, single–chip solution is the core of the magnetic scanning and signal generation process. The position data is generated in real time and made available using SSI or bidirectional BiSS C interfaces. Incremental SIN/COS analogue signals and ABZ signals can also be used.
