Description
OD:75.4 mm frameless motor
is a high‑speed 75.4 mm outer‑rotor frameless BLDC torque motor, powered by standard 48 VDC industrial power supply. It delivers 485 W rated power, 1.4 Nm continuous rated torque and up to 4.2 Nm peak torque, with maximum speed reaching 4500 RPM.

Housing‑less split stator‑rotor design enables full embedding into customer‑custom mechanical structures. At only 233 g weight and 21.2 mm stack length, it achieves outstanding power‑to‑size ratio. Low cogging ensures smooth rotation and high dynamic response for high‑speed precision motion. We provide custom winding, cable modification and OEM/ODM service for system integrators, robot manufacturers and automation equipment suppliers.Suitable for high‑speed compact automation equipment:

  • 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. Please provide your specific requirements, and we will offer a tailored solution for you.
