Product Description:

The MDD090B-N-030-N2L-130PR0 synchronous motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor built for digital drive controllers, it converts regulated current into mechanical rotation for axes that need precise velocity and torque control in automated assembly cells and material-handling lines. Its construction supports closed-loop motion control and direct coupling to gearboxes or load shafts, giving machine builders a standardized drive element that matches the electrical and mechanical interface conventions used across the MDD family.

It mounts through a centering pilot of 130 mm, ensuring coaxial alignment with adjoining mechanics, and its power and feedback connectors exit on the right side to simplify cable routing in crowded cabinets. During continuous stall conditions, the motor can deliver 7.2 Nm of torque without overheating, while a rated rotational frequency of 3000 min⁻¹ is its synchronous operating speed under nominal line frequency. Motion data are returned to the drive by a digital servo feedback (DSF) transducer, enabling high-resolution position regulation. Connection is achieved with a circular industrial connector, and the housing follows the standard enclosure format for this frame. The B length code provides the active iron length needed for this torque without increasing the motor diameter.

The motor is specified without a blocking brake, so load holding must be provided by the drive or by external mechanics. A keyway is machined into the shaft to transmit torque reliably, and the output end is protected with a shaft seal that limits lubricant egress and dust ingress at the coupling interface. Frame size 090 keeps overall mass moderate and supports installation in multi-axis gantries. Standard dynamic balancing minimizes vibration during high-speed duty, while the motor uses a single-ended shaft without a side B extension to reduce axial length.
