Direct Drive Rotary Motors

Our direct drive motors and actuators utilize brushless DC motor technology to create unique motion solutions. While BLDC motors have been around for a very long time, the detailed application of this technology has countless variants. Our team of engineers work closely with the customers to understand the application to create an optimized solution. We provide both frameless solutions to support the maximum level of integration into our customers machines as well as fully integrated solutions. Our product range covers rotary, limited angle, long and short stroke linear motion. We offer very low profile and large through hole solutions. All these products can be tailored to suit your specific needs.

Optimized solutions range from direct drive motor components to fully engineered, validated, and tested products and value-add assemblies.

We have an in-house mechatronics team that is expert in packaging our motors, encoders and drive electronics into full integrated solutions.

ARC Low-Profile DDR Motors for Arc Segment and Large Diameter Motion

Low-Profile DDR Motors for Arc Segment and Large Diameter Motion.
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
