In the Galileo project of the remarkable EU global satellite navigation system, the special motors used for 25 telescopes are provided by Physis. Relying on the special driving device developed by Physis, the radio telescope in the Atacama Desert can rotate at a constant speed of 360 degrees in a year with high precision.
Physis has been focusing on the design and application for large-scale direct drive motors for more than 20 years. Direct drive motors are used in astronomical telescopes, wind power, tidal power generation and traction system, etc.
It was recognized in 2022 as the “first (set)” equipment in China. The diameter of the cable car direct drive system is 2.5 m, and its power is up to 1050 kW.
The large direct drive servo motor developed by Physis has been applied to the international large-scale astronomical telescope. Physis has become the global supplier of high-end motion control device for astronomical observatory.
Modular, double air gap, double armature magnetic circuit topology greatly improve the power density of the motor and make its structure more compact, which is very applicable for MW-class wind power system.
The large-scale direct drive servo motor developed and manufactured by Physis has been successfully applied to the bucket wheel machine for Baosteel Group.
Physis provides Otis with 20T and 25T direct drive servo motors for the High-speed elevator of high-rise buildings. Among them, 25T motor has rated torque 8500 Nm, rated speed 100 rpm, efficiency close to 98%.
Physis direct drive R&D technology can meet the requirements of high dynamic response, high precision and high reliability of Rotary Table. Physis has become a leading supplier of high-end machine tool equipment worldwide.
