Product Description:

The MDD090C-N-030-N2M-110PR2 is a brushless AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, this motor converts commanded current into tightly regulated rotary motion for indexing tables, handling axes, and other automated machinery. It serves as the electromechanical actuator that translates velocity and torque commands from the controller into precise shaft movement in packaging lines, assembly stations, and material-transfer equipment. The brushless design supports smooth torque delivery and avoids the wear associated with mechanical commutation. This makes it suitable for closed-loop applications that require repeatable starts, stops, and speed changes throughout the operating cycle.

At its nominal operating point, the rotor reaches 3000 rpm, a speed that supports rapid indexing and consistent cycle timing. At standstill, the motor can continuously deliver 10.4 Nm of torque, allowing the axis to resist static load without overheating during normal duty. An internal brake provides 11.0 Nm of holding torque, allowing vertical axes to remain locked when power is removed. Position information is generated by an integrated multi-turn absolute encoder, so the control system knows the shaft angle across multiple revolutions without a homing cycle. Motion and status data are carried over Digital servo feedback (DSF) signals that interface directly with compatible drive modules.

The mechanical interface uses a centering diameter of 110 mm, which helps align the motor accurately with gearboxes or machine frames. Power and feedback cables exit on the right side, and a sealed connector arrangement keeps external connections compact. Output torque is transferred through a keyway shaft, and a shaft seal helps keep coolant or dust away from the bearing area. Standard dynamic balancing reduces vibration across the C-length stator, while the 090 frame size keeps thermal mass moderate for frequent acceleration. A single-ended shaft without a side-B extension reduces overhung load and leaves more space around the rear of the motor for adjacent machine components.
