Overview

A full digital feedback solution using a multi-turn absolute encoder is crucial for ensuring that no position information is lost in the event of a power outage in modern day motion control systems. The legacy battery-backup or gear-based multi-turn solutions either require maintenance or are unable to meet the mounting requirements of space constraint applications.

This webinar will provide attendees with insights into the latest motion feedback encoders with Broadcom's energy harvesting multi-turn (EHMT) counter, based on Wiegand sensing technologies. The focus will be on the miniature 20 mm OD size AS20-M42M series encoders. Continuing on Broadcom's innovative tradition, this high-performance encoder has built-in smart calibration and self-diagnostic features that enable ease of installation into small motors, while ensuring product reliability in the end application. The integrated encoder ASIC combines the powerful magnetic sensing single-turn with the MT counter ASIC. This versatile encoder is available in a variety of industrial standard protocols, e.g. SPI/SSI/BiSS-C/RS485.

Attendees will gain an understanding of the benefits of energy harvesting absolute encoders in terms of increasing angular accuracy, enhanced hysteresis performance, and reducing maintenance costs. The webinar is aimed at engineers, designers, and technical decision makers involved in motion control development seeking to optimize their designs and accelerate adoption of high performance control systems. By attending this webinar, participants will gain a competitive edge in the state-of-the-art miniature feedback solution.
