HTDW-5022-02-DNE Planetary Joint Module – 22:1, 3.5Nm, 13Nm Peak, CANFD/CAN

The HTDW-5022-02-DNE is a compact planetary joint module engineered for lightweight robotic arms, exoskeletons, and precision automation joints. At just 50 × 47.4 mm and 322 g, it delivers 3.5 Nm rated torque and 13 Nm locked-rotor torque through a 22:1 planetary reduction, with dual 14-bit encoders for closed-loop position, velocity, and current control.

Key Features:

• Planetary gear reducer – 22:1 reduction, high drive efficiency in a compact 50 mm body.
• 3.5 Nm rated / 13 Nm locked-rotor torque – solid output for lightweight joints.
• Self-designed brushless DC motor – low cogging torque and low torque ripple.
• Dual 14-bit absolute encoders – accurate position and torque feedback for closed-loop control.
• CANFD / CAN communication – 5 Mbps baud rate, easy integration with existing robot control architectures.
• Wide voltage range – 12–50.4 V DC input, 24 V rated.
• Lightweight – only 322 g, ideal for weight-sensitive multi-joint robots.
