MDD090A-N-020-N2L-110GA2
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090A-N-020-N2L-110GA2 from the MDD Synchronous Motors series by Bosch Rexroth Indramat combines compact design with precision engineering for digital drive controllers. This Product Type: Motor for digital drive controllers is built around a Motor Size: 090 frame and a Motor Length Code: A profile, optimizing torque-to-inertia ratio in a standard-height housing. A Centering Diameter: 110 mm and Housing: Standard footprint ensure seamless integration into existing machine assemblies. Standard balancing and a plain shaft deliver smooth operation and minimal vibration across the entire speed range.
Performance is driven by a robust Continuous Torque at Standstill: 3.7 Nm rating, enabling reliable holding and low-speed control. Integrated Motor Feedback: Digital servo feedback (DSF) provides high-resolution position sensing and real-time diagnostics. For safety-critical applications, a built-in Holding Brake: With blocking brake offers an Holding Brake Torque: 11.0 Nm restraint, locking the rotor when power is removed. A Shaft Seal: With shaft seal prevents contamination ingress, and the Shaft Type: Plain shaft simplifies coupling to gearboxes or pulleys. Standard balancing maintains longevity by reducing bearing loads under dynamic load profiles.
Electrical and mechanical connections are standardized with a Connection Type: Connector on Connection Direction: Side A, streamlining cabling during installation and maintenance. The omission of a secondary shaft end (Standard without side B shaft end) focuses the design on core drive performance without unnecessary overhang. Engineered for compatibility with Bosch Rexroth Indramat digital drives, the MDD090A series accelerates commissioning through preloaded parameters and automatic feedback synchronization. With its combination of high torque density, precise feedback, and rugged sealing, the MDD090A-N-020-N2L-110GA2 is an ideal solution for packaging, robotics, and high-precision automation environments.

Frequently Asked Questions
What role does the thermal time constant of 45 minutes play in heat management?
The 45-minute thermal time constant defines how long the motor takes to reach thermal equilibrium, directly influencing cooling system requirements and the motor’s ability to handle extended operation without overheating.
Would the motor’s 3.7 Nm continuous torque affect its suitability for high-load applications?
The 3.7 Nm continuous torque makes the motor well-suited for medium-duty tasks but might be insufficient for high-load or high-torque applications, requiring higher torque motors for demanding conditions.
How does the windings inductance of 27.7 mH impact the system's control precision?
The windings inductance impacts the speed and accuracy of the motor’s response to control signals, with higher inductance potentially slowing down response times and making it less ideal for precise high-speed operations.
How would the 2000 min⁻¹ nominal motor speed influence system dynamics?
The nominal speed of 2000 min⁻¹ positions the motor for medium-speed applications, providing a balance between performance and efficiency, but not suitable for applications requiring extremely high or low speeds.
Could the housing design influence the MDD090A-N-020-N2L-110GA2 motor’s cooling efficiency?
Yes, the standard housing design impacts cooling efficiency by facilitating natural convection and heat dissipation. In applications with higher thermal loads, forced air cooling may be necessary to optimize performance.
