摘要
A low cost, high resolution optical encoder for a brush-less DC motor comprises reflective sensors, and a movable diskcooperating with a stationary pattern to provide a pattern ofreflective and non-reflective areas for the sensors that can beused to generate motor positional information as well as commuta-tion drive signals.
