MDD093B-N-020-N2M-110PR2, Bosch Rexroth Indramat, MDD Synchronous Motors is a high-precision digital AC servo motor engineered for demanding automation environments. The permanent-magnet rotor couples with an integrated multiturn absolute encoder to provide continuous, real-time commutation, rotor position, and speed data. With a Motor Size: 093 frame and a compact Motor Length Code: B, this unit balances high torque density with a minimized envelope. A factory-installed blocking brake delivers immediate load retention when de-energized, enhancing safety during standstill or power interruption.



Designed for seamless integration into digital drive systems, this servo motor offers Digital servo feedback (DSF) and an Encoder: Integrated multiturn absolute encoder for unmatched feedback fidelity. It provides a Continuous Torque at Standstill: 14.5 Nm and a Holding Brake Torque: 22 Nm from the Holding Brake: With blocking brake, while spinning at a Nominal Speed: 2000 min⁻¹ under rated conditions. The precision-machined Centering Diameter: 110 mm and standardized Shaft Type: keyway per DIN 6885 ensure exact alignment and torsional rigidity. A sealed housing with Shaft Seal: With shaft seal and Balancing: Standard construction resists contaminants and vibration, and the right-hand Connection Direction: Right utilizes a robust Connection Type: Connector interface for simplified wiring.



Engineered for reliability and quick commissioning, the MDD093B-N-020-N2M-110PR2 seamlessly interfaces with Bosch Rexroth digital drive controllers to enable closed-loop torque, speed, and position control. Its standardized form factor and mounting dimensions facilitate drop-in replacement and modular machine architectures. This servo motor’s rugged design and advanced feedback capabilities make it ideal for robotics, CNC machining centers, packaging machinery, and any precision motion application where performance and uptime are critical.

How does this motor handle transient loads without saturating current control systems?

The MDD093B-N-020-N2M-110PR2 reaches a peak current of 76.0 A during high-demand cycles. System designers must validate that the drive can tolerate this spike without thermal or circuit protection trips.

How does rotor inertia influence system response in dynamic axis control?

This model has a rotor moment of inertia of 29 x 10⁻⁴ kg·m². It balances responsiveness and mechanical damping, which suits mid-inertia applications with moderate acceleration profiles.

What are the control implications when tuning drive gains for this Bosch Rexroth Indramat model?

The torque constant of the MDD093B-N-020-N2M-110PR2 is 0.86 Nm/A, affecting loop gain calculations. Accurate tuning ensures precise torque control under varying load conditions.

How does winding resistance affect thermal rise during sustained torque output?

This motor features 0.77 Ohms of winding resistance at 20 °C. This must be accounted for in thermal models, especially in enclosures with limited airflow or continuous duty cycles.

What considerations exist for drive matching in high-inductance servo loops?

The windings inductance is rated at 7.6 mH, impacting the servo amplifier's current loop bandwidth. Tuning must compensate to avoid sluggish response or phase lag at high speeds.
