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
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Stator outer diameter | 50-115 mm classes | Primary sizing input for torque constant and packaging. |
| Continuous torque class | 0.8-6+ Nm (by frame and cooling condition) | Defines sustained operating capability under duty cycle. |
| Cogging behavior target | Ultra-low ripple design preference | Impacts 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.

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.
