Linear Motors

A linear motor axis consists of a linear module with an integrated linear motor which is able to move the carriage back and forth. Linear motors are linear direct drives with uniform, linear force. They are particularly suitable for fast positioning and feed movements at high accuracy.

Advantages of the ESR linear motors:

Compared to other linear drive systems (such as toothed belt or ball screw), an ESR linear motor incorporates the advantages of a direct drive providing high acceleration and speeds at high rigidity and precision.

Linear Motors As Modular System

Instead of completely assembled linear motor axes, the components are also available individually to be integrated directly into the linear axis of a machine. This way, linear movements with high dynamics can be realized in a space saving way. For information on the linear motor modular system, please see page Linear Motor Components.
