The business area of the HDS Group is providing the value of total motion control in the precision control field.
Total Motion Control
As a technology and skills team providing total motion control, the HDS Group merges the technologies making up total motion control with the human resources of our engineers and skilled technicians to deliver the products that enable the kind of motion customers want.
Combining the HarmonicDrive®, AccuDrive®, and HarmonicPlanetary® high-precision speed reducers with actuators made of motors, sensors and other parts, as well as the drivers, controllers, and other system elements for drawing out their top performance, we provide high-added-value products with clear advantages over competing products.
The HDS Group offers two main kinds of product lineups. One is mechatronics products providing motion control by integrating speed reducers, motors, sensors, drivers, controllers and other system elements. The other is our lineup of standalone speed reducers including the HarmonicDrive® precision reducers and the AccuDrive® and HarmonicPlanetary® planetary speed reducers.
Products that combine speed reducers, motors, sensors, drivers, controllers and other system elements to provide the motion desired by customers are called mechatronics products. Mechatronics products are specific embodiments of the total motion control that is the business domain of the HDS Group. The mechatronics products of the HDS Group have gained a distinctive position in the market, benefiting from the synergies of our highly competitive HarmonicDrive® and the AccuDrive® and HarmonicPlanetary® planetary speed reducers with original motors, sensors, and control technologies for maximizing their performance and unique features. They are mainly used in semiconductor manufacturing equipment and other leading-edge applications.
This speed reducer applies the elastic dynamics of metal to make possible precise positioning. Consisting of just three components, it achieves a high speed reduction ratio (from 1/30 to 1/320 of standard reducers), and can maintain highly precise positioning due to the absence of clearance where the teeth engage. It is used in many different applications including industrial robots requiring high positioning accuracy and aerospace-related equipment where compact size and light weight are needed.
This high-precision, high-rigidity planetary speed reducer brings to low speed reduction ratio applications in the 1/3 to 1/45 range the same precision processing technological know-how that goes into the HarmonicDrive®. It achieves high rotational accuracy with an original backlash-prevention mechanism. The broad range of applications include industrial robots and machine tools.
The HDS Group is made up of Harmonic Drive Systems Inc. and ten consolidated subsidiaries as well as one equity method affiliates for a total of eleven companies. They are engaged chiefly in the development, production, and sales of precision speed reducers and mechatronics products in which they are used. The main regional markets for HDS Group products are Japan and Asia, North America, and Europe. Harmonic Drive Systems Inc. is in charge of the markets in Japan, South Korea, Taiwan, and Southeast Asia. The China market is handled mainly by our consolidated subsidiary Harmonic Drive Systems (Shanghai) Co., Ltd., the North American region by consolidated subsidiary Harmonic Drive L.L.C., and markets in Europe, the Middle East, Africa, India, and South America by consolidated subsidiary Harmonic Drive SE.
