IN BRIEF: Miniature encoder for high-speed cutting applications

A miniature encoder capable of measuring spindle speeds well over 40,000rpm has been designed for high-speed cutting applications. It works by magnetically scanning a toothed wheel fitted to the shaft. And because it is a non-contact method there is, in theory, no limit to the speed it can measure, according to Motor Technology, which has […]
