MDD093C-N-020-N5L-110GB2

The Bosch Rexroth Indramat MDD093C-N-020-N5L-110GB2 motor is a high-precision unit in the MDD Synchronous Motors series, designed for demanding industrial automation environments. This controller-ready servo motor features a nominal speed of 2000 min⁻¹ and delivers a continuous torque at standstill of 19.5 Nm, rising to 28.0 Nm with surface cooling engaged. Its robust design yields a peak current of 96.5 A for short-term high-load demands, while the rotor exhibits a moment of inertia of 42 × 10⁻⁴ kg·m², ensuring a balanced response between dynamic acceleration and stability. With a total mass of 22.0 kg and a housing rated IP65, this motor combines compact dimensions with weatherproof protection. Early integration is facilitated by its plain shaft, centering diameter of 110 mm, and connection direction: Side B, allowing straightforward mounting in diverse mechanical assemblies.

The MDD093C-N-020-N5L-110GB2 excels in performance, achieving continuous current at standstill of 21.4 A (30.8 A with surface cooling) to maintain torque consistency in long-run operations. Under peak conditions, it produces a theoretical maximum torque of 60.6 Nm, supported by a torque constant at 20 °C of 0.91 Nm/A and a windings inductance of 6.1 mH paired with a winding resistance of 0.56 Ω, ensuring crisp current response and precise torque control. The motor’s integrated digital servo feedback (DSF) encoder affords high-resolution position feedback for closed-loop control, optimizing synchronization and reducing overshoot in rapid positioning tasks. Its holding brake with torque of 22 Nm secures the load during power interruptions or emergency stops, enhancing safety. Standard balancing and a mechanical design rated for continuous operation further contribute to smooth, low-vibration operation across the entire speed range.

Reliability is engineered through a rugged standard housing treated to RAL 9005 black coating, resistant to dust and water ingress per the IP65 protection rating. The motor conforms to an insulation class F specification, supporting ambient temperatures from 0 to 45 °C without performance degradation. With a Motor Length Code “C” and Motor Size “093”, it integrates seamlessly into existing drive cabinets and digital drive controllers. Its compatibility with industry-standard mounting interfaces and drive algorithms makes it ideal for robotics, CNC machinery, packaging lines, and other industrial automation applications where precision, durability, and ease of integration are paramount.
