The MD880LC series engineering AC drive (multi-drive system) is a new high-end water-cooled AC drive from Inovance. Available in single-drive and multi-drive topologies and positioned for high-end drive applications, this series offers high performance and reliability. Inheriting the design philosophy of the MD880 series engineering AC drives, this series leads in module structure, power density, control strategies, response speed, and control accuracy compared with other AC drives in China. It is widely used in metallurgy, ships, marine drilling rigs, shield machines, high-power water-cooled test benches, and large continuous production equipment. As a water-cooled single-drive product of the MD880 family, this series is specifically designed to control AC asynchronous induction motors and permanent magnet synchronous motors for ships, shield machines, and offshore oil platforms. It features high power density, compact structure, and high reliability, and provides multiple motor control modes including V/f control, sensorless vector control (SVC), and feedback vector control (FVC).
