Machine tool industry

In CNC machine tools, the AC servo electric machine tool worktable is mainly used for motion control. In order to display or control the displacement of the machine tool worktable, it is often necessary to convert it into a digital quantity. For this purpose, position sensors are required. Commonly used ones include code disks, induction synchronizers, synchronizers and gratings, etc. CNC machine tools generally use code disks and gratings (hereinafter referred to as encoders) for position detection.

Understanding Hollow Shaft Encoders: Key Insights for Electronics and Sensor Applications

Hollow shaft encoders are pivotal components in various electronic and automation applications, serving as vital tools for measuring rotational position or speed. Unlike traditional encoders, hollow shaft encoders feature a central opening that allows them to be mounted directly onto a rotating shaft without the need for additional couplings or adapters. This unique design provides several benefit
