Frameless Torque Motor 38LW03

Frameless Torque Motor 38LW03 is engineered for lightweight robotic platforms where high speed, minimal inertia, and compact size are critical. Powered at 48 VDC, it reaches 10,300 RPM while maintaining 0.102 N·m rated torque and 0.32 N·m peak torque, enabling rapid and responsive motion control.

The motor features a 7 pole-pair configuration with balanced electrical characteristics:

• Rated Current: 2.8 A

• Peak Current: 8.8 A

• Resistance: 1.2 Ω

• Inductance: 0.48 mH

• Back-EMF Constant: 2.3 Vrms/krpm

With an outer diameter of 38 mm and an ultra-light 60 g construction, the 38LW03 is ideal for quadruped robots, lightweight joint actuators, and compact direct-drive motion modules where mass and responsiveness are critical.

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. These specifications serve as essential design references for engineers evaluating compatibility, load conditions, and performance expectations.
