MDD112C-N-020-N2L-130PB2
MDD Synchronous Motors
MDD112C-N-020-N2L-130PB2, Bosch Rexroth Indramat, MDD Synchronous Motors form a robust AC servo solution designed for high-precision industrial automation. The unit runs at a nominal speed of 2000 min⁻¹ to deliver a continuous torque output of 10.5 Nm and a peak torque of 30.7 Nm. A winding resistance of 1.40 Ω combined with an inductance of 16 mH provides tight current regulation and swift dynamic response. Built to endure harsh environments, it carries an IP65 protection rating and meets insulation class F requirements for reliable operation.
Optimized performance stems from a continuous torque at standstill of 28.0 Nm and a peak current threshold of 110.5 A, enabling rapid acceleration profiles. The torque constant of 0.94 Nm/A ensures proportional force output across the speed range, while the rotor moment of inertia of 170 x 10⁻⁴ kg·m² stabilizes high-speed operation. A precision-machined centering diameter of 130 mm secures alignment, and standard balancing minimizes vibration. The integrated holding brake delivers 40.0 Nm of locking torque for safe stops, and the Black Prime Coat (RAL9005) enclosure, rated Standard, adds corrosion resistance. Massing 48 kg, the motor is specified as a Motor for digital drive controllers with connection routed through Side B for seamless cabinet layout.
Engineers will value the Digital servo feedback (DSF) system for real-time position and speed monitoring, which integrates directly with Rexroth digital drives for closed-loop precision. The compact shaft type keyway interface and standard housing facilitate plug-and-play replacement in existing setups. Rugged design and industry-standard connectors reduce downtime, making the MDD112C-N-020-N2L-130PB2 ideal for robotics, CNC machining, and automated assembly lines where accuracy and uptime are paramount.
