RDM-A Series Rod Motors for Linear Thrust Generation in Space-Constrained Applications

May 21, 2024
Akribis Systems' RDM-A Series Rod Motors have a tubular design to distribute magnetic flux evenly along the circumference of the stator in applications that need high motor forces and smooth linear motion.

An addition to its varied motion control product line, Arkibis' RDM-A Series rod motors are for space-constrained applications that require high motor forces and smooth linear motion.

Compact in size, the rod motors have a tubular design to distribute magnetic flux evenly along the circumference of the stator. They achieve continuous forces from 2.1 to 137.8N and peak forces from 6.2 to 413.4N. An air gap between the coil and magnet track enables non-contact axial linear movement and steady force production over the length of the stroke, and ironless construction ensures cog-free motion.

A multimover option allows single motor control over multiple movers on one track to simplify complex, multiaxis applications. 


  • Fast and precise
  • Full use of flux lines
  • Ironless—no cogging
