descriptions of the term:

Linear Power Stage

Aside from the so-called "choppered stepper motor power stages“ there are drivers based on other principles.
The linear amplifier ist one of the types of power stage without a chopper. The linear amplifier distinguishes itself by generating an exceptionally precise current curve, which augments positioning accuracy and step resolution. Considerably improved EMC characteristics are obtained without the chopper.

The linear power stage is suitable when:

  • extremely high positioning accuracy is required
  • operating in noise-sensitive environment (EMC)
  • Fields of Application: Measurement technology – Optics –  Physics technology – Medical technology – Research ...
