Infinity™ Series Linear Arc Motor

Infinity™ Series Linear Arc Motor, 112 mm Radius

The Infinity™ Series enables OEMs to move light payloads in smooth and accurate arc-shaped and full 360-degree rotary motion profiles. Ultra-thin arc-shaped motor segments can be used individually or interconnected to create exact partial arc segment motion or full 360-degree rotary motion. Modular construction allows for virtually unlimited diameter and large through holes. This level of flexibility is not possible with conventional motor designs.


  • Ultra-low profile, lightweight construction

  • Modular design easily configured into a partial arc segment or full 360-degree rotary motion

  • Virtually unlimited diameter possible for rotation of payloads or convenient routing of cables, optics, sensing technologies, and other system elements

  • Smooth, accurate motion

  • Easy integration into system design

  • Compatible with a wide range of drives and controllers

  • Custom windings and form factors available to meet application requirements
