Capability Highlights

  • Motor, reducer, brake, and encoder integrated in one compact assembly
  • Supports prototype-to-production architecture continuity
  • Designed for high shock events and frequent acceleration/deceleration

Typical Applications

  • Humanoid lower-body joints (hip/knee/ankle)
  • Payload-sensitive upper-body joints
  • Research-to-pilot humanoid programs

Engineering Focus

  • Define continuous/peak torque and duty-cycle envelope
  • Validate brake strategy for emergency stop and hold behavior
  • Confirm encoder resolution and control loop compatibility
  • Map thermal boundary conditions before sample freeze

RFQ Checklist

  1. Target joint location and motion range
  2. Continuous and peak torque at operating speed
  3. Controller interface and feedback requirements
  4. Prototype quantity, pilot quantity, and target SOP date
  5. Destination country and preferred trade terms

Risk Controls

  • Architecture mismatch between sample and final control stack: Freeze interface revision and control assumptions before prototype build.
  • Insufficient thermal margin at duty peak: Run thermal scenario review with real duty cycle and enclosure constraints.
  • Brake behavior not aligned with safety strategy: Define brake trigger, release logic, and fault fallback at RFQ stage.

Buyer FAQ

Can this module be tuned for our joint-specific torque curve?

Yes. Torque, reduction, encoder, and brake combinations can be configured based on your duty profile and control strategy.

Do you support prototype and pilot quantities before MP?

Yes. We support staged quantities and revision-controlled ramp from sample validation to repeat production.

How should we share integration constraints?

Send CAD envelope, interface drawings, and control assumptions together so feasibility feedback is actionable in the first round.
