Detail Information

MG-H109-50 Hollow-Shaft Motor

The MG-H109-50 is a high-torque hollow-shaft brushless servo motor designed for robot joints, precision rotary stages, optical equipment, and industrial automation systems.It integrates a high-torque brushless motor, servo driver, position-feedback system, and communication interfaces into a compact Ø109 × 49 mm housing. The motor features a Ø50 mm hollow bore, providing ample space for multiple power cables, communication wires, optical fibers, pneumatic lines, or mechanical components.

Operating from 24–48 VDC, the MG-H109-50 delivers 4 N·m rated torque, 15 N·m peak torque, and 384 W rated power. Its high torque density, large through-bore, and precision closed-loop control make it suitable for demanding direct-drive rotary applications.

Product Advantages

Motor features and dimensions

Ø50 mm Large Hollow Bore

The MG-H109-50 provides a minimum Ø50 mm hollow passage for routing multiple power cables, signal wires, optical fibers, pneumatic lines, or mechanical components through the rotation axis.The large hollow bore simplifies internal routing and reduces interference from external wiring, making it suitable for robot waist joints, optical systems, radar platforms, and complex rotary mechanisms.

4 N·m Continuous Torque

The motor delivers 4 N·m rated torque, providing reliable continuous output for robot joints, rotary stages, and automated rotary axes.Its direct-drive construction eliminates the need for an additional gearbox, avoiding mechanical backlash, transmission friction, and gear-related noise.


Robot joint motor specifications

15 N·m Peak Torque

The MG-H109-50 provides up to 15 N·m peak torque, supporting startup, rapid acceleration, position holding, and short-duration impact loads.The continuous current is below 8 A, while peak current can reach 40 A. The allowable duration of peak output depends on the driver’s current limit, power-supply capacity, cooling conditions, and ambient temperature.

±0.004° Positioning Accuracy

The specified repeatability and absolute positioning accuracy are both ±0.004°, making the motor suitable for precision positioning and angle-control applications.Its speed variation rate is below ±0.5%, while the specified speed resolution is 0.0001 Hz, supporting smooth and stable low-speed operation.

Robot application scenarios

20-Bit Absolute Encoder

The motor integrates a 20-bit single-turn absolute encoder, providing detailed angular feedback for position, speed, and torque control.The absolute encoder allows the controller to identify the single-turn rotor position at startup, reducing the need for conventional homing procedures.

Low-Noise, Low-Maintenance Operation

The specified operating noise is below 50 dB, making the motor suitable for laboratory equipment, optical instruments, service robots, and other noise-sensitive systems.
