Briefing
Detailed
The MG-H49-12 is a compact hollow-shaft brushless servo motor designed for robot joints, precision gimbals, rotary stages, and automation equipment. It integrates a brushless motor, servo driver, and position-feedback system into a compact housing, reducing the need for external drivers, encoder boards, and additional wiring. With a 12–24 VDC operating range, the MG-H49-12 delivers 0.15 N·m rated torque, 0.45 N·m peak torque, and a maximum speed of 2,700 rpm. Its rated power is 24 W, with an instantaneous power capability of up to 144 W. The motor, servo driver, and position-feedback system are integrated into a single unit, reducing external components, mounting space, and electrical connections.With dimensions of Ø49 × 24 mm and a weight of approximately 115 g, the MG-H49-12 is suitable for compact robot joints, gimbals, inspection systems, and precision rotary mechanisms. The motor features a minimum Ø12.5 mm hollow bore, allowing power cables, signal wires, optical fibers, or pneumatic lines to pass through the rotation axis.This design simplifies internal routing and reduces cable interference, twisting, and pulling during rotary motion. The MG-H49-12 integrates a 16-bit single-turn absolute encoder, providing detailed angular feedback for closed-loop motion control.The encoder supports direct single-turn position detection at startup, reducing the need for conventional homing procedures. The specified repeatability and absolute positioning accuracy are both ±0.006°, 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. The MG-H49-12 uses a 6703 P5-grade bearing, providing stable support for the hollow rotor.The bearing has a rated dynamic load of 1 kN and a rated static load of 0.66 kN. Actual allowable external loads should be evaluated according to mounting conditions, load direction, moment arm, and service-life requirements. The specified operating noise is below 50 dB, making the motor suitable for laboratory equipment, optical instruments, service robots, and other noise-sensitive systems. Joint actuation for bipedal and full-body humanoid platforms Safe, precise motion for cobot arms and grippers Power assist and rehabilitation exoskeleton systems Robotics labs, university projects, and prototyping Surgical robots and rehabilitation equipment Automated guided vehicles and smart manufacturingMG-H49-12 Hollow-Shaft Motor
