Encoder feedback directly at the rotating axis unlocks higher positioning precision
Absolute position feedback can be critical in robotic applications, where the robot arm position must be determined at all times, even after a loss of power. In torque motor implementations, the accuracy of the rotational encoder is often the key to the accuracy of the entire system.
In many servo-robotic applications, rotary position feedback from an encoder at the motor provides sufficient positioning accuracy at the robot arm, but when applications demand higher precision, primary or secondary feedback in the form of an axis-mounted magnetic rotary encoder from Balluff could be the answer. Balluff can supply a variety of magnetic encoder rings and disks of various shapes and sizes, in incremental and absolute variations.
