Mitsubishi MDS-EH-SP-40 Spindle Drive Unit for MDS-EH Series

The Mitsubishi MDS-EH-SP-40 (MDS-EH-SP-40) is an industrial spindle drive unit engineered for high-performance velocity and position control in CNC machine tool applications. Belonging to the Mitsubishi MDS-EH series, this drive is designed to operate spindle motors requiring precise speed regulation and reliable torque response across heavy-duty machining environments. Technically, the unit features a rated output current of 18 A and supports a 400 V class power supply. It accommodates a three-phase AC input voltage range of 380 to 480 V AC at 400 V, 415 V, or 440 V, as well as a direct-current bus input of 513 to 648 V DC. Built with an IP20 protection rating to shield internal electronics against solid particles, the unit operates efficiently in ambient temperatures ranging from 0 to +55 degrees Celsius. The MDS-EH-SP-40 delivers seamless integration into compatible CNC systems, providing robust power delivery and thermal stability for continuous spindle operations in industrial manufacturing facilities.
