Capability Highlights

  • Outrunner and inrunner options for different torque-response goals
  • Direct housing integration without bulky servo shell
  • Supports winding and KV optimization by application

Typical Applications

  • Collaborative robot joints
  • Medical robotic articulation
  • Precision direct-drive gimbal and stage systems

Engineering Focus

  • Outrunner vs inrunner selection by inertia and bandwidth target
  • Thermal path design and housing integration controls
  • Cogging ripple control and low-speed smoothness requirements

Key Evaluation Matrix

MetricTypical RangeWhy It Matters
Stator outer diameter50-115 mm classesPrimary sizing input for torque constant and packaging.
Continuous torque class0.8-6+ Nm (by frame and cooling condition)Defines sustained operating capability under duty cycle.
Cogging behavior targetUltra-low ripple design preferenceImpacts precision motion quality in low-speed control.

Compliance and Trade Guidance

CE, RoHS, and REACH documentation support is available by project scope. HS classification should be treated as reference guidance only and must be confirmed by importer/broker based on destination rules and final product configuration.

  • Confirm required compliance document list before sample planning.
  • Include destination market and declaration scope in your RFQ message.
  • Review detailed guidance in Resources / Compliance.

RFQ Checklist

  1. Target continuous and peak torque per axis
  2. Voltage window and KV target
  3. Envelope constraints and thermal dissipation assumptions
  4. Encoder, cable, and assembly integration requirements

Risk Controls

  • Thermal saturation in compact enclosure: Review thermal path and continuous-load envelope before tooling lock.
  • Magnetic/assembly tolerance drift: Define rotor-stator concentricity and QA checkpoints in sample plan.

Buyer FAQ

Can you support both outrunner and inrunner frameless architectures?

Yes. We can support both structures and advise based on torque arm, inertia, and response requirements.

Can we request cogging and thermal test reports?

Yes. Test-report scope can be aligned during RFQ and sample validation.
