Fast-reacting optical encoder feedback system for miniature motor-driven applications

摘要

Motor control system demands for higher accuracy, higher speed and miniaturisation are increasing. Optical encoders are used as motor position-sensing devices. To do this, the optical encoder signal chain must have a high level of accuracy when measuring the motor position. A high-speed, high-throughput ADC accurately captures information and feeds motor position data to the controller. The AD7380's speed, density, and performance answer the industry's demand while enabling higher levels of accuracy and optimisation in the position-feedback system.
