Frameless Torque Motor 172LW04

Frameless Torque Motor 172LW04 is designed for applications where high torque at very low speed is critical. Powered at 12 VDC, it operates at 30 RPM while maintaining 4.5 N·m rated torque and 6.0 N·m peak torque, enabling precise and stable motion control in heavy-load systems.

The motor features a 13 pole-pair configuration with robust electrical characteristics:

• Rated Current: 8.2 A

• Peak Current: 11 A

• Resistance: 0.41 Ω

• Inductance: 0.83 mH

• Back-EMF Constant: 34.2 Vrms/krpm

With a large 172 mm outer diameter, the 172LW04 is well suited for direct-drive actuators, rotary mechanisms, and integrated motion systems used in smart agricultural machinery and other low-speed, high-torque applications.

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.
