Application-led engineering

Frameless Torque Motors

Integrate a stator and rotor set into your own joint or direct-drive assembly.

Conceptual motor architecture showing stator, rotor and shaft interface
Conceptual architecture schematic. Configuration and drawings are defined for each project.

Engineering scope

  • Hollow-shaft layout review
  • Cogging and torque-ripple targets
  • Installation and thermal interface planning

Application fit

  • Robot joints
  • Direct-drive stages
  • Precision positioning

OEM engineering and sourcing teams evaluating frameless torque motors.

Start with the operating requirements

Architecture, performance and cost are reviewed together. Share the values you know; identify the values that need engineering input.

  • Rotor support and assembly tolerances
  • Continuous torque with actual cooling
  • Air gap and installation stack-up
  • Prototype quantity, annual volume and target schedule

Define the validation before the prototype

Unclear operating conditions or interface assumptions

Confirm the operating map, interfaces and acceptance criteria before prototype release.

Prototype-to-production changes

Agree drawing revisions, critical characteristics and the change-control process.

Ratings, prototype timing, NRE, tooling, testing and production commitments are confirmed in the project scope. This overview does not represent a stocked model or an approved medical device.

Project questions

What should we provide for the first review?

Share rotor support and assembly tolerances, continuous torque with actual cooling, air gap and installation stack-up, prototype quantity and annual volume. Unknown values can be discussed during feasibility review.

Are specifications and lead times fixed?

These are custom engineering project directions. Ratings, validation scope, pricing, NRE and lead time are confirmed for the agreed configuration; no off-the-shelf rating or universal delivery promise is implied.

Bring your application into the design review.

Send your target operating points, packaging constraints and volume plan.
