High-performance Brushless Servo Drive for Retrofit Market
The SA5400 Servo Drive and the matching M5400 Servo Motor series were specifically developed for the retrofit market, replacing outdated large Brush DC and Brushless AC servomotors and drives no longer supported by original OEMs. Designed for versatility and flexibility, the SA5400 drive features state-of-the-art 3D modeling, high torque, MS connector interfaces, and a wide selection of feedback devices such as tachometers, resolvers, and encoders. Combined with matching motors and cables, it provides a cost-effective solution for major machine retrofits as well as new OEM applications, including radar systems, antennas, material handling, and CNC machines.
