  • Designed for rapid thermal dissipation

Typical Applications

  • Direct-drive joints and agile robotic limbs
  • Gimbal and camera pointing systems
  • Inspection robot drive modules

Engineering Focus

  • Thermal continuous rating vs. peak rating
  • Rotor inertia minimization
  • Cogging torque harmonic analysis

Key Evaluation Matrix

MetricTypical RangeWhy It Matters
Cogging torque< 1% of continuous torqueEnsures smooth tracking and excellent force transparency.
Thermal time constantApplication dependentDictates how long peak torque can be safely maintained.
Torque density> 15 N·m/kgKeeps robot limb inertia low for fast accelerations.

RFQ Checklist

  1. Target torque/speed envelope and duty cycle
  2. Mounting envelope constraints
  3. Control update rate and sensing architecture
  4. Sample acceptance and repeatability criteria
  5. Expected lifecycle and maintenance assumptions

Risk Controls

  • Overheating under stall: Embed thermistors directly in the winding overhang for fast thermal cut-off.
  • Rotor demagnetization: Use high-temperature-grade Neodymium magnets and active current limiting.

Buyer FAQ

Is this suitable for quasi-direct-drive (QDD)?

Absolutely. It is designed specifically to pair with low-ratio (e.g. 1:6) planetary gears.

Do you offer frameless versions?

Yes, frameless stator/rotor sets are available for deep integration.
