MDD090B-N-040-N2M-130PB2
MDD Synchronous Motors
MDD090B-N-040-N2M-130PB2, Bosch Rexroth Indramat, MDD Synchronous Motors offers a high-performance solution for precise motion control in demanding industrial environments. As a Motor for digital drive controllers, its compact Motor Size 090 and Motor Length Code B provide a balanced footprint, while the large Centering Diameter 130 mm ensures straightforward integration into standard machine interfaces. An integrated multiturn absolute Encoder delivers exact position data at power-up, minimizing homing sequences and boosting uptime. Robust construction and conformity to Indramat design principles guarantee consistent performance across extended duty cycles.
Engineered to maintain precision under load, this motor features a Continuous Torque at Standstill 7.2 Nm and a Holding Brake Torque 11.0 Nm, ensuring reliable load retention when power is removed. The built-in Holding Brake with blocking mechanism locks the shaft firmly, complemented by a factory-installed Shaft Seal to guard against contaminants in harsh environments. Standard Balancing minimizes vibration at its Nominal Speed 4000 min⁻¹, while the keyed Shaft Type and standard side-B shaft end simplify mechanical coupling. Side B Connection Direction and robust Connection Type Connector enable clean routing of power and feedback cables, and the standard housing accommodates both natural convection and optional cooling upgrades.
Seamless compatibility with digital servo feedback (DSF) systems makes the MDD090B-N-040-N2M-130PB2 an ideal choice for multi-axis servo drives, robotics, and automated assembly lines. Its integrated design reduces component count, streamlines wiring, and enhances reliability by eliminating external feedback devices. With proven Bosch Rexroth Indramat quality, this motor delivers years of maintenance-free operation even in the most challenging applications.

Frequently Asked Questions
What advantages does the multiturn absolute encoder provide on the MDD090B-N-040-N2M-130PB2?
It delivers absolute position at power-up for reducing or eliminating homing moves and shortening recovery after stops. It DSF option with integrated multiturn capability is used across MDD series motors.
How does the 11.0 Nm blocking brake help in vertical or holding applications on MDD090B-N-040-N2M-130PB2?
The brake locks the shaft during power loss or E-stop, preventing load drift on Z-axes, gantries, or indexing stations. It also simplifies maintenance by allowing safe static positioning while mechanics are serviced.
How does standard balancing at nominal speed influence performance on MDD090B-N-040-N2M-130PB2?
Standard balancing reduces vibration at 4000 min⁻¹, protecting bearings and improving servo tuning margins. Lower vibration also helps maintain tight contour accuracy under dynamic load.
What’s the role of the shaft seal specified for MDD090B-N-040-N2M-130PB2?
The seal helps keep dust and fluids out of the front bearing area, supporting long service life in harsher environments. MDD motors are commonly available with protection suitable for industrial settings (IP 65 noted across the series).
Is the keyed shaft on the MDD090B-N-040-N2M-130PB2 compliant with common coupling standards?
Yes—MDD motors use DIN-compliant keyway variants across the family, allowing straightforward coupling to hubs and pulleys. This ensures interchangeability with standard transmission components.
