MDD090B-N-040-N2L-130GL2

The Bosch Rexroth Indramat MDD090B-N-040-N2L-130GL2 is a high-performance member of the MDD Synchronous Motors family, engineered for precise motion control in demanding industrial environments. This digital AC servo motor integrates a permanent-magnet rotor design with an onboard encoder for commutation, rotor position, and speed feedback, ensuring reliable operation across a broad range of speeds. Featuring a compact Motor Size of 090 and a Motor Length Code B, the motor achieves a nominal speed of 4000 min⁻¹ while maintaining smooth dynamic response. The MDD090B offers a robust mechanical interface with a Centering Diameter of 130 mm and a plain shaft output, simplifying alignment and coupling to downstream mechanisms. An integrated blocking brake with a Holding Brake Torque of 11.0 Nm provides secure hold in applications requiring immediate stops or vertical axis support.

Engineered with attention to critical specifications, the MDD090B-N-040-N2L-130GL2 includes Standard Balancing and a Standard Housing that contribute to vibration reduction and structural rigidity. Continuous torque at standstill is rated at 7.2 Nm, ensuring stable holding capability under load. The Digital Servo Feedback (DSF) system delivers high-resolution position and speed information directly to compatible drive controllers, while the inclusion of a Shaft Seal protects internal components from particulate ingress. Connections are provided via a Connector interface mounted on the Left side of the housing, and the output Shaft Type is a plain shaft with a Standard shaft end (without side B shaft end). This model is specifically classified as a Motor for digital drive controllers, optimizing integration with Rexroth Indramat drive electronics.

Operational performance is characterized by precise control of acceleration and deceleration profiles, enabled by the motor’s permanent-magnet excitation and encoder-based commutation scheme. At low speeds, the motor sustains continuous torque without thermal derating, and the high nominal speed expands the usable speed range for machine applications. The integrated holding brake engages within milliseconds, providing immediate mechanical lock for safety and positioning tasks. Vibration and noise are minimized through the standard balancing procedure, and the robust shaft seal extends service life in environments with moderate contamination. The digital feedback loop ensures rapid response to command updates, supporting high-throughput applications where cycle times and positioning accuracy are critical.

Integration of the MDD090B-N-040-N2L-130GL2 into automated systems is streamlined by its compatibility with Bosch Rexroth Indramat digital drive controllers, which support advanced tuning, diagnostics, and motion profiles. Its compact form factor and standardized interface allow designers to deploy the motor in robotics, packaging machinery, CNC equipment, and assembly lines with minimal mechanical modification. The combination of continuous torque, high-speed capability, and fast-acting brake makes this motor ideal for pick-and-place units, indexing tables, and synchronized multi-axis systems. As part of the MDD Synchronous Motors series, it delivers the precision and reliability required for modern manufacturing and process automation.
