Product Description:

The MDD090B-N-030-N2M-130GL1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts command signals into controlled rotary motion for positioning and handling stations on automated lines. Size 090 construction and length code B give it a compact envelope, while the standard housing helps protect the internal windings from airborne contaminants. The motor is suited for applications that require repeatable starts, stops, and speed changes under closed-loop control.

During operation, the unit can hold a load at standstill with a continuous torque of 7.2 Nm, and it reaches a nominal speed of 3000 rpm for mid-range axis duties. Alignment to gearboxes or couplings is simplified by a centering diameter of 130 mm. Power, brake, and feedback conductors terminate through a connector positioned on the left side of the stator, which helps keep cable routing orderly in multi-axis installations. Position data are transmitted through digital servo feedback, allowing the drive to adjust current in real time. A standard shaft seal limits lubricant migration, and the housing layout supports enclosed machine installations.

For static holding duties, the integral blocking brake supplies 6.5 Nm of torque, helping prevent downward drift on vertical loads when power is removed. Output torque is delivered through a plain shaft without a secondary side B extension, which reduces overall motor length. Commutation accuracy is maintained by the integrated multi-turn absolute encoder, which retains position across power cycles and removes the need for a homing move after startup. The rotor uses standard balancing, which helps keep vibration controlled at rated speed. These characteristics support stable motion on medium-duty industrial automation axes where secure holding and consistent feedback are required.
