MDD090A-N-020-N2L-110PR1

The Bosch Rexroth Indramat MDD090A-N-020-N2L-110PR1 servo motor represents a high-precision solution in the MDD Synchronous Motors lineup, engineered for demanding automation and motion control applications. Manufactured by Bosch Rexroth Indramat, this Digital AC Servo Motor combines advanced permanent-magnet rotor design with integrated encoder technology for commutation, rotor position, and speed feedback. The MDD090A-N-020-N2L-110PR1 delivers consistent, repeatable performance through a robust housing and optimized thermal characteristics. With its compact footprint and standardized mounting interfaces, this motor is well suited to retrofit installations as well as new machine designs.

The servo motor’s mechanical and electrical characteristics are defined by critical parameters: it features a Centering Diameter of 110 mm, Motor Length Code A, and a nominal continuous torque at standstill of 3.7 Nm. The rotor is balanced to Standard specification and sealed via a With shaft seal arrangement to protect against contaminants. Electrical feedback is provided by the integrated Digital servo feedback (DSF) system, while the drive interface uses a Connector type Connection Type positioned in the Right Connection Direction. The unit employs a keyway Shaft Type conforming to DIN 6885 sh. 1, 8-68 Edition and terminates in a Standard (without side B shaft end) Shaft End.

Operational performance is anchored by a Nominal Speed of 2000 min⁻¹, with rapid acceleration response driven by the motor’s low inertia and high torque-to-inertia ratio. A Holding Brake included with blocking brake delivers a Holding Brake Torque of 6.5 Nm, ensuring secure stops and position retention under power-off conditions. The motor’s Motor Size 090 frame provides robust torque density while maintaining low noise and minimal vibration, enhancing system stability. Its integrated encoder-based feedback loop minimizes overshoot and settling time, supporting precise contouring and dynamic load changes in real time.

System integration is simplified through compatibility with standard Bosch Rexroth Indramat digital drive controllers, enabling seamless interoperability and auto-configuration. The motor’s digital servo feedback and standardized mechanical interfaces reduce engineering effort and commissioning time. Ideal applications include robotics, CNC machining centers, packaging machinery, and high-speed indexing systems where precise speed, position control, and holding functionality are critical. This servo motor’s combination of proven design, robust construction, and digital control capabilities makes it an excellent choice for advanced automation projects.
