What makes it work
HX-08LCM Magnetic Encoder Coreless Bus Servo – Dual-Axis 8kg High Torque, 360° High-Speed Motor for Robotics
The HX-08LCM is a high-performance intelligent magnetic encoder bus servo equipped with a premium coreless motor and a 12-bit high-resolution magnetic encoder, supporting 360° continuous rotation and pinpoint positioning with 8kg·cm of torque.
Product Description
The HX-08LCM is a high-performance intelligent magnetic encoder bus servo equipped with a premium coreless motor and a 12-bit high-resolution magnetic encoder. Supporting 360° continuous rotation and pinpoint positioning, it pairs strong power with precise control. Built-in trapezoidal velocity profiling and PID algorithms deliver 8kg·cm of torque with silky-smooth response and jitter-free starts, stops, and motion—balancing raw output with fluid movement. Real-time multi-parameter telemetry, an anti-stall self-protection algorithm, and multiple safety mechanisms work across both hardware and software to ensure reliable operation.
Key Features & Applications
Acceleration Start/Stop
The built-in trapezoidal acceleration/deceleration control algorithm allows customizable speed and acceleration, ensuring powerful output, reducing impact to extend servo lifespan, and ensuring smoother joint movement.
Angle Readback Feedback
With built-in angle feedback and readback, the servo quickly reads joint angles for accurate robot posture capture.
Three Stopping Modes
Hold torque mode maintains output torque when powered on, release torque mode disengages it automatically when power is off, and damping mode smoothly releases torque for braking. Modes can be switched flexibly to suit various applications.
Real-Time Parameter Feedback
This bus servo provides real-time temperature, voltage, and position feedback, allowing for internal data monitoring and preventing unexpected shutdowns.
Key Features
The HX-08LCM servo combines intelligent control with a robust structure. Its bus connection simplifies wiring, while the all-metal gears and dual-axis design ensure stable operation. Additionally, it features multiple protection mechanisms and precise feedback.
ID Recognition & Bus Communication
Each servo supports a customizable ID for identification. The default ID is set to 1, and the ID can be modified as needed.
Serial Bus Daisy-Chaining
Servos are connected via serial communication, reducing cable clutter and enhancing the product's clean, streamlined design.
Integrated Drive IC
Operating at 7.4 V, the high-quality built-in H-bridge driver maximizes motor control efficiency. Its smooth, continuous, and reliable power delivery provides a robust electronic foundation for precise robotic actuation.
Precise 360° Position Control
A high-precision potentiometer delivers real-time angle readback for instant tracking. This enables effortless closed-loop control, meeting any high-precision motion choreography needs.
One-Click Calibration
Install at any 360° angle. With 40 address inputs, simply press a button to calibrate the current position to the central position.
Multiple Protection Mechanisms
The servo integrates multiple protections, including stall, overheat, overload, overvoltage, and overcurrent, ensuring long-term, stable operation.
Compact Frame
The lightweight and compact miniature design ensures balanced load distribution and highly stable dual-shaft operation.
Multi-Turn Precise Control
Up to 7 turns of absolute position control and feedback. After power loss, the turn count is cleared and only the absolute position feedback is retained.
