Product Description:

The MDD090B-N-030-N2M-130GL0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for connection to digital drive controllers, the unit converts controlled electrical input into precise rotary motion for conveyor axes, pick-and-place modules, and indexing stations on automated lines. Its mechanical envelope, electrical interfaces, and feedback hardware are sized for fast integration where repeatable velocity and position control are required. Its synchronous design also supports smooth acceleration and stable servo response during frequent starts, stops, and speed changes.

Dimensional alignment is handled by a centering pilot of 130 mm, allowing the housing to seat concentrically on the machine flange and keep bearing loads symmetrical. At standstill, the motor can deliver a continuous torque of 7.2 Nm, and during routine operation it reaches a nominal speed of 3000 rpm. Power and feedback conductors exit on the left side, which simplifies cable routing when the motor is mounted close to cabinet walls. One circular connector carries the three-phase supply and signal pins, reducing assembly time. The output interface is a plain shaft, enabling backlash-free coupling with hubs that clamp directly onto the ground surface. The housing layout also suits compact axis arrangements where nearby tooling or guarding leaves little free space around the motor body.

Position data is exchanged through digital servo feedback, giving the drive controller real-time rotor angle for high-resolution current loops. Feedback originates from an integrated multiturn absolute encoder, so the axis powers up with absolute position knowledge and does not require homing routines. This feedback arrangement helps the control system maintain accurate commutation during low-speed motion and supports a predictable restart after a power cycle. Because the motor ships without a blocking brake, the axis must rely on drive torque or external clamping devices to secure vertical or safety-critical loads when supply power is lost. A shaft seal protects internal bearings from coolant or dust ingress, and the absence of a side B shaft end shortens the overall length for compact installations.
