Since commencing production of rotary actuators in 2018, HONPINE has continuously grown and refined its product categories based on the diverse application fields of its customers. This article introduces HONPINE's two major series of rotary actuators: HPG and HAG. These are high-precision rotary actuators developed and manufactured by HONPINE specifically for CNC machine tool and robotics applications. Contact HONPINE, and we can recommend the most suitable rotary actuator based on your specific application.

First, let’s introduce the HPG High-Precision Rotary Actuator

Design Philosophy of the HPG High-Precision Planetary Rotary Actuator for Machine Tools

This rotary actuator is widely used in 4-axis and 5-axis machine tools, electronics and semiconductor equipment, precision CNC machine tools, 3C equipment, precision laser processing equipment, LED equipment, inspection devices, medical instruments, printing machinery, spray painting design, glass processing, precision measuring instruments, and more. As this actuator is commonly used in machine tools, HONPINE placed strong emphasis on precision, rigidity, and ease of maintenance during its development.

Superior Performance of the HPG Rotary Actuator

1,Equipped with a high-precision, high-rigidity planetary gear structure. Positioning accuracy is less than 35 arcsec, with repeat positioning accuracy of the T series being less than 5 arcsec.

2,Based on the characteristics of the planetary structure, it offers 3-4 times higher torsional rigidity than the (HAT series) of the same torque rating. The reducer has high torque capacity, with peak starting/stopping torque capable of reaching 2.5 times the motor's rated overload.

3,The external drive can be disassembled separately; partial component damage does not require replacing the entire module.

4,Motor features dual bearing support; the encoder-side bearing has its inner and outer rings axially fully fixed.

5,Brake and encoder are isolated to prevent contamination.

6,High efficiency: Reducer efficiency reaches over 88%. High efficiency ensures high dynamic responsiveness, making it particularly suitable for the machine tool industry.

7,Hollow shaft: Allows internal routing for air tubes and cables, offering ease of use and convenient installation.

8,Compatible with mainstream drives on the market;Standard Tamagawa protocol (BISS, SSI optional), enabling plug-and-play operation.

Next, let’s introduce the HAG Robot Rotary Actuator

Design Philosophy of the HAG Built-in Drive Rotary Actuator for Robots

The 48V voltage version of this rotary actuator can be widely used in collaborative manipulators, medical robotic arms, humanoid robots, special-purpose robots, and other fields. HONPINE thoroughly considered factors such as compact structure, operational stability, precision, torque, and cable routing during its design.

Superior Performance of the HAG Rotary Actuator

1,Utilizes a harmonic drive reducer structure. Under rated conditions, the accuracy maintenance life is 15,000 hours.

2,Built-in drive offers high integration, reducing external connections.

3,Saves motor matching and debugging effort; simple and easy to use, shorter in length, and lighter in weight.

4,High performance: The entire series can achieve the maximum average load torque of the reducer at their rated torque.

5,Low noise: Excellent structural rigidity ensures smooth operation across the entire speed range with low noise.

6,Hollow shaft: Allows internal hollow cabling, facilitating quick setup of serial multi-joints without cable routing hassles.

In-depth Integration: Beyond Simple Assembly

Superficially, a rotary actuator seems to be just an integration of a reducer, a frameless torque motor, an encoder, and a driver.
However, through years of production experience, HONPINE has discovered that the integration of a rotary actuator is far more complex than mere hardware assembly. A unified rotary actuator requires precise tolerance matching and dimensional chains for every component. Through countless cycles of machining and compatibility testing, HONPINE has significantly reduced vibration and noise in its rotary actuators, achieved better inertia matching, minimized axial and radial runout, and reduced issues like misalignment. Our technical team has also accumulated extensive solution expertise for various fields. If you are interested in rotary actuators, contact us for the optimal solution recommendation.
