Successful Application of H-TRUM-120 Ultrasonic Motors in the laser communication of XINGYUN No.1&No.2 and QILU No.1 satellites

Release time:

2022-08-25

Large hollow ultrasonic motors were applied in the laser communication systems of XINGYUN No.1&No.2 and QILU No.1 satellites, which were launched successfully. Up to now, they are running well and have made outstanding contribution to the mission of laser communication between satellites.

The ultra-large (diameter of 120 mm) type of hollow traveling wave rotary ultrasonic motors (H-TRUM-120), developed by our company, possess the remarkable performance of ultra-high accuracy, ultra-fast response, ultra-low speed and ultra-high stability. H-TRUM-120 excellently meets the requirements of the laser communication terminal pointing system (APT).

After passing the test verification, the motors have been applied in the laser communication systems of XINGYUN No.1&No.2 and QILU No.1 satellites, which were launched successfully on May 2020 and April 2021 respectively. Up to now, they are running well and have made outstanding contribution to the mission of laser communication between satellites.
