The Advantages Of Using A Linear Motor May 12, 2018

A motorized linear stage is essential for a wide range of applications, and provides programmable control of position in one or more axes.

There are multiple technologies to choose from when selecting a motorized linear stage. The simplest is based on a stepping linear motor, with its rotary motion converted to linear motion via a pulley and belt, or a lead screw.

Fully integrated stepping linear motor/lead screw assemblies have recently become widely available. They avoid the need for a rotary coupling and a lead screw bearing, and provide a compact, cost effective solution for many motorized linear stage requirements.

A higher performance and higher cost solution replaces the stepping linear motor with a brushless rotary servo motor. While these can achieve higher speed and precision, they require a rotary encoder and are not yet available as integrated motor/lead screw assemblies.
