Nanjing Hangda Supercontrol Technology Co., Ltd.

Nanjing Hangda Supercontrol Technology Co., Ltd. was founded in January 2017 by Academician Zhao Chunsheng of the Chinese Academy of Sciences, and is supported by the Institute of Precision Drive and Control at Nanjing University of Aeronautics and Astronautics, the State Key Laboratory of Mechanical Mechanics and Control, and the National–Local Joint Engineering Laboratory for Ultrasonic Motors. For nearly thirty years, Academician Zhao Chunsheng has established and led the Institute of Precision Drive and Control, conducting in-depth, systematic research on ultrasonic motor theory and its applications. He has received numerous national and provincial‑ministerial science and technology awards, including two Second Prizes for National Technological Invention, one First Prize in National Defense Science and Technology, and one First Prize for Technological Invention from the Ministry of Education. His work “Ultrasonic Motor Technology and Applications” was awarded the National Excellent Publication Award. He has also filed and been granted multiple national invention patents related to ultrasonic motors (patent numbers: 201410728602.9, 201410728419.9, 201610615815.X, 202011154547.9, etc.). Furthermore, he has developed more than 60 novel types of ultrasonic motors, several of which have been successfully deployed in both military and civilian sectors, including those used in the Chang’e‑3, Chang’e‑4, and Chang’e‑5 lunar missions; the Micius quantum science experimental satellite; the Xingyun‑2 satellites No. 01 and No. 02; the HaiSi‑1 satellite; the Qilu‑1 satellite; the Chaohu‑1 satellite; as well as the Fucheng‑1 and Shenqi satellites.

Fast response

High torque-to-mass ratio (3–5 times that of electromagnetic motors)
It can achieve low speed and high torque without a gear reduction mechanism.
Fast response (on the order of milliseconds), high resolution, and excellent control performance.

Excellent electromagnetic compatibility

The deflection reciprocating motion rate reaches up to 1 kHz (enabling fast‑response control).
Power-off self-locking and excellent electromagnetic compatibility.

The power of continuous improvement

Highly educated technical professionals and seasoned equipment‑manufacturing experts—production resources: engineering installation and construction personnel, coupled with state‑of‑the‑art high‑tech tools.

Diverse shapes

Low noise (within 100 mm, <45 dB)
It can operate in extreme environments such as vacuum, high temperatures, and low temperatures.
Diverse shapes: round, square, annular, and cylindrical, among others;

High overload resistance

The efficiency of ultrasonic motors does not decrease as their size is reduced.
Extremely slow speed: 1r/day
Can withstand high overloads exceeding 10,000 g.
