MDD090C-N-030-N2K-110PB1
The MDD090C-N-030-N2K-110PB1 from Bosch Rexroth Indramat is part of the MDD Synchronous Motors series, designed as a high‑performance motor for digital drive controllers in industrial automation. It delivers a Nominal Speed of 3000 min⁻¹ and features a Torque Constant At 20°C of 0.53 Nm/A, ensuring precise torque control per ampere of current. With a Peak Current rating of 117.8 A, this motor excels at handling rapid dynamic loads and maintaining stable operation under variable conditions. Its primary application is in machinery requiring consistent speed and torque accuracy for indexing, conveyor drives, and servo-controlled processes.
Incorporating advanced mechanical and electrical design, this motor boasts a Rotor Moment Of Inertia of 53 × 10⁻⁴ kg·m² for optimized acceleration and deceleration performance. The Windings Resistance At 20°C is 0.46 Ω, supporting efficient current flow and minimizing heat generation. A Centering Diameter of 110 mm and a standard square flange housing ensure seamless integration into existing mounts. The motor size code "090" with length code "C" balances compactness and power density. For feedback, an Integrated Absolute Encoder provides precise position information, while the built‑in Shaft Seal and side‑mounted connectors (Connection Direction “B”) protect against contaminants.
Built to withstand harsh environments, the MDD090C‑N‑030‑N2K‑110PB1 offers IP65 protection and operates reliably between 0 °C and +45 °C. The unit includes a blocking brake with Holding Brake Torque of 6.5 Nm, energized at 24 V DC to secure loads when powered down. Standard balancing and a robust housing deliver long service life, while dual cooling methods—natural convection and surface cooling—enhance thermal management. With its high protection rating, precise feedback, and versatile mounting options, this synchronous motor delivers reliable performance and reduced maintenance in demanding industrial applications.
