MDD090A-N-020-N2M-110PA2

The Bosch Rexroth Indramat MDD090A-N-020-N2M-110PA2 servo motor, part of the MDD Synchronous Motors series, is a high-performance Digital AC Servo Motor designed for precision motion control in industrial automation. This permanent-magnet motor features a compact Motor Length Code A and a robust Centering Diameter of 110 mm, delivering reliable torque and dynamic response. Equipped with a With blocking brake providing 11.0 Nm of holding brake torque, it ensures positional stability under load and secures the drivetrain in emergency stops. The MDD090A-N-020-N2M-110PA2 is optimized for use with digital drive controllers, offering seamless integration and efficient power delivery for complex motion profiles. Its design emphasizes long-term reliability, low maintenance, and precise rotary positioning for demanding applications.

This servo motor offers a wide array of critical specifications: a Continuous Torque at Standstill of 3.7 Nm enables sustained holding capacity without oversizing the drive. The Motor Size 090 housing, with standard balancing and Standard Housing construction, maintains mechanical integrity under dynamic loads. A nominal speed of 2000 min⁻¹ is achieved through precision winding and magnetic materials, while the With shaft seal ensures protection against contaminants. The output configuration features a Shaft With Keyway Per DIN 6885 sh. 1, 8-68 Edition and a Standard (without side B shaft end) arrangement for straightforward coupling. Connection is handled via a Connector interface on Side A, simplifying installation in confined enclosures.

Operational performance is driven by an advanced feedback system: the Integrated multiturn absolute encoder provides high-resolution position data for closed-loop commutation and speed regulation. Digital servo feedback (DSF) enables direct communication with servo drives, reducing latency and improving control bandwidth. The keyway shaft design per DIN standards ensures secure torque transmission, while the standard balancing minimizes vibration at high rotational speeds. The motor’s permanent-magnet rotor and encoder for commutation deliver rapid acceleration and deceleration, supporting cycle-intensive tasks. Standard balancing and a keyed shaft facilitate consistent operation in multi-axis assemblies and robotic joints.

System integration is streamlined for digital drive controllers, leveraging the MDD series’ compatibility with Bosch Rexroth Indramat controllers and third-party automation systems. The motor’s standardized dimensions and connection scheme enable drop-in replacement and modular machine design. Target applications include CNC machining centers, pick-and-place robots, packaging machinery, and automated assembly lines where precise torque, position accuracy, and reliable braking are essential. With its combination of Bosch Rexroth Indramat engineering, digital feedback, and robust mechanical design, the MDD090A-N-020-N2M-110PA2 is tailored to meet the rigorous demands of modern industrial automation.
