The 68LW03 is a compact frameless torque motor delivering 0.55 N·m rated torque and 1.65 N·m peak torque at 3000 RPM, operating at 220 VAC, ideal for precision robotic joints and direct-drive motion systems.
Frameless Torque Motor 68LW03
Frameless Torque Motor 68LW03 is engineered for precision direct-drive systems where compact size, smooth operation, and electrical stability are essential. Powered at 220 VAC, it reaches 3000 RPM while maintaining 0.55 N·m rated torque and 1.65 N·m peak torque, supporting responsive and accurate motion control.
The motor features a 7 pole-pair configuration with balanced electrical characteristics:
Rated Current: 1.2 A
Peak Current: 3.6 A
Resistance: 9 Ω
Inductance: 9 mH
Back-EMF Constant: 30.8 Vrms/krpm
With an outer diameter of 68 mm, height of 21.7 mm, and 243 g weight, the 68LW03 is well suited for compact robotic actuators, precision automation equipment, and integrated motion systems requiring consistent torque and clean electrical behavior.

This specification table presents the fundamental electrical and mechanical characteristics required for proper application and system integration. Rated values indicate continuous operating conditions, while additional parameters highlight peak capabilities, performance limits, and control requirements.
