Product Description
OD:135 mm frameless motor           
Is a high‑torque 135 mm outer‑rotor frameless BLDC torque motor, operating at 48VDC. It delivers 8 Nm continuous rated torque and strong 24 Nm peak torque, with rated power of 1760 W and maximum speed up to 2100 RPM.

Housing‑free split stator‑rotor design enables direct embedding into customer‑designed mechanical assemblies. Its 42‑pole topology provides excellent torque density, low cogging torque and ultra‑smooth rotation. This compact motor weighs only 964 g with stack length of 28 mm. Custom winding, cable harness modification and full OEM/ODM service are available for robot and automation integrators.

  • Collaborative robot joints & high‑speed robotic actuators
  • Industrial automation and rotary positioning platforms
  • Portable medical automation devices
  • High‑speed optical inspection equipment
  • AGV / AMR drive and steering units
  • Special‑purpose high‑speed automated machinery
Customization is available upon request for this motor series, including but not limited to rated voltage, speed, torque, lead wire specifications, outlet orientation, shaft configuration, encoder/sensor integration, and more.
