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

The Mitsubishi MDS-E-SP-40 (MDS-E-SP-40) is an AC spindle drive unit designed for CNC machine tool drive systems within the Mitsubishi MDS-E series. This drive unit controls and powers AC spindle motors, delivering high-speed rotation, precise cutting velocity, and stable torque regulation for automated machining operations. Operating on a 200 V class power system, the unit supports an AC supply voltage of 200 to 240 V AC across three-phase electrical configurations, as well as a direct current supply range of 270 to 324 V DC. It features a rated current capacity of 15 A to ensure dependable output during demanding spindle acceleration and continuous operation. Engineered for industrial control enclosures, the MDS-E-SP-40 provides IP20 degree of protection against particulate ingress and solid objects. It is rated to operate reliably within an ambient temperature environment ranging from 0 to +55 degrees Celsius. This spindle drive unit is typically utilized in CNC milling centers, lathes, and high-precision machine tools requiring synchronous spindle motion control under the MDS-E drive platform.
