I. Test Bench Overview

The voofu 100,000 N·m Permanent Magnet Drive Transmission Performance Type Test Bench is an advanced test platform jointly built by voofu Permanent Magnet Technology Co., Ltd., the 712th Research Institute of China Shipbuilding Industry Corporation, and Soochow University. The test bench covers an area of nearly 600 square meters and integrates a 2MW-level energy-recovery permanent magnet motor and a permanent magnet coupler/adjustable speed drive test system (including two 2MW load motors, two 2MW converter cast iron platforms, torque measuring instruments, and a measurement and control system, etc.). The total investment in enterprise technology development instruments and equipment has reached 12.4653 million RMB. The completion of this test bench marks a major breakthrough in the construction of basic research and development facilities for permanent magnet transmission and permanent magnet drive in China, with experimental capabilities significantly enhanced.
