Product Description:

The MDD090B-N-020-N2M-130GB2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled rotary motion for machine tools, handling systems, and packaging equipment. The synchronous motor design supports accurate speed regulation and repeatable positioning on axes that must respond quickly to changing commands. Because power conversion and position feedback are integrated into one motor package, it serves as a compact drive component for automated machinery.

The unit delivers a continuous standstill torque of 7.2 Nm, allowing stable force production while the rotor is stopped or moving slowly. Under rated electrical frequency, it sustains a speed of 2000 rpm, which suits applications that favor moderate rotational speed with high precision. A flange centering diameter of 130 mm aligns the housing during mounting, and dynamic balancing helps keep vibration low across the operating range. Power and feedback connections are positioned on side B, which can simplify cable routing in compact machine layouts. Position data is provided by an integrated multi-turn absolute encoder, so the drive receives both angular position and revolution count for closed-loop control without battery support. The motor has size 090 and length code B, and it uses a standard housing style.

During downtime or an emergency stop, the blocking brake supplies 11.0 Nm of holding torque to secure vertical or high-inertia loads. The motion control loop uses Digital servo feedback (DSF) to transmit encoder information with cyclic redundancy checking. Torque is transmitted through a plain shaft, and contamination is limited because the unit is built with a shaft seal. The drive-side shaft end is standard, while the opposite face has no shaft extension, which helps keep the motor compact for close-coupled gearboxes or couplings.
