Description
HT-N3 Robotic Joint Servo Motor with 6:1 Planetary Gearbox
The HT-N3 Robotic Joint Servo Motor is a compact brushless joint motor engineered for robotic joints, humanoid robots, exoskeleton systems, robotic arms, and precision automation equipment. This version is supplied without the integrated MIT driver, making it ideal for developers and system integrators who already use their own motor controllers or custom servo control platforms.
The actuator integrates a brushless servo motor, 6:1 steel planetary gearbox, and built-in position sensing into a lightweight, compact assembly. Operating from 12–24V, it delivers 3 Nm rated torque, 9 Nm peak torque, and up to 400 RPM output speed after reduction, providing an excellent balance of torque density, responsiveness, and installation flexibility.
Designed for CAN-based robotic systems and custom motion controllers, the HT-N3 offers reliable mechanical performance while allowing complete freedom to select the preferred driver architecture for research, industrial automation, educational robotics, and robotic product development.

Who is this version designed for?
It is intended for developers, research laboratories, universities, and automation engineers using their own motor controller or custom control system.
Can I connect it to my own controller?
Yes. This version is suitable for integration into custom control platforms that support compatible brushless servo motor control and CAN communication.
What is the rated torque?
The HT-N3 provides 3 Nm rated torque and 9 Nm peak torque.
What gearbox is integrated?
A 6:1 precision steel planetary gearbox with approximately 15 arcmin backlash.
What voltage does the motor support?
Rated voltage is 24V, with an operating range of 12–24V.
Is this suitable for robotic arm joints?
Yes. The compact structure and high torque density make it suitable for robotic arm joints, humanoid robots, exoskeletons, and other articulated robotic systems.
What is the difference between this version and the integrated actuator version?
