MDD090B-N-040-N2M-110PB1

The Bosch Rexroth Indramat MDD090B-N-040-N2M-110PB1 servo motor in the MDD Synchronous Motors series delivers a robust digital AC drive solution optimized for precision automation. This motor integrates digital servo feedback and an integrated multiturn absolute encoder to achieve high contouring accuracies and responsive motion control. Featuring a nominal speed of 4000 min⁻¹ and continuous torque at standstill of 7.2 Nm, the unit supports demanding positioning tasks in compact machine designs. Its standard closed housing protects internal components and enables installation in six orientations per DIN IEC 34-7. The design also incorporates a blocking brake for immediate holding capability, making it suitable for vertical or emergency stop applications.

Detailed specifications define the MDD090B-N-040-N2M-110PB1’s performance envelope. The motor’s center diameter of 110 mm and shaft type: keyway support precise coupling and torque transmission. Rated balancing to DIN VDE 0530 ensures vibration levels are controlled at the standard balancing class. The housing is coated in black prime paint with optional blower mounting for surface cooling. Electrical connections include side‐B connectors for power, feedback, and blower interfaces. The unit is coded as motor length B with a motor size designation of 090, and it carries Class F insulation for thermal endurance up to a maximum ambient temperature of 55 °C.

Operationally, the MDD090B motor demonstrates high reliability through dual winding sets and shaft sealing rings that guard against contaminants. The integrated blocking brake offers a holding torque of 6.5 Nm, while the closed housing design resists external hazards. Thermal deformation on the A-side mandates reseating after extended storage, and a one-year warranty covers manufacturing defects. The maximum rated duty cycle of 15 minutes provides ample capacity for intermittent heavy loads. Axial and radial forces are accommodated by robust bearings, and the unit ships globally with consistent quality control.

System integration is streamlined when pairing the MDD090B-N-040-N2M-110PB1 with Bosch Rexroth digital drive controllers for real-time tuning and feedback processing. The Side B connector format allows either straight or angled plug configurations to suit space constraints. Its compatibility with standard motion control architectures makes it ideal for CNC machine tools, high-precision assembly lines, packaging equipment, and robotics. The combination of precise feedback, compact form factor, and multi-orientation mounting ensures seamless deployment in automated manufacturing and processing systems where accuracy and uptime are paramount.
