A traditional servo rotary actuator consists of a rotor, stator, housing, bearings, end caps, and feedback components. A frameless motor removes all redundant mechanical structures and retains only the electromagnetic conversion core. The rotor becomes a direct part of the load shaft, while the stator is integrated into the machine structure through bonding, locking, or potting.

Hello everyone, I’m Allen Li, founder of HONPINE. Today, I’d like to talk about how HONPINE seized the opportunity during the rapid rise of the humanoid robotics industry and how the HPJM harmonic reducer integrated joint module managed to stand out in this highly competitive market.

The HATF Harmonic Servo Rotary Actuators support harmonic drives of models 11, 14, 17, 20, 25, 32, 40, 50, and 58, with rated torque from 4 N·m to 1200 N·m. They feature multi-turn absolute encoders with Tamagawa protocol: single-turn 17-bit / multi-turn 16-bit, or single-turn 23-bit / multi-turn 16-bit. Dual-encoder configurations are also available.Based on the HAS solid model, the HATF actuators add an integrated flange, allowing mounting when end-face installation is not possible. This design provides better support for axial and radial loads, while enhancing vibration and impact resistance.

The HAT Hollow and Standard Harmonic Servo Rotary Actuators support harmonic drives of models 11, 14, 17, 20, 25, 32, 40, 50, and 58, with rated torque from 4 N·m to 1200 N·m and outer diameters ranging from 62 mm to 220 mm.They feature multi-turn absolute encoders with Tamagawa protocol:Single-turn 17-bit, multi-turn 16-bit, or Single-turn 23-bit, multi-turn 16-bit.Custom dual-encoder configurations are also available. The harmonic actuators can be directly mounted via the end face, making them ideal for lightweight or space-constrained applications.
