Product Description:

The MDD090B-N-030-N2L-110PA0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical commands from the associated drive into precise rotary motion for automation axes, packaging stations, and handling units. Its compact format supports closed-loop motion control where accurate speed regulation, repeatable positioning, and smooth response are required. The design also fits applications that need reliable servo performance without a large mounting footprint.

During continuous operation, the motor delivers a standstill torque of 7.2 Nm, providing steady force for holding or low-speed positioning tasks. Application cycle speeds can reach a nominal rotor velocity of 3000 rpm, which suits fast indexing and general servo motion. Position information is returned to the drive through digital servo feedback, enabling precise regulation without external feedback devices. The unit is supplied without a blocking brake, so static holding must be handled by the drive or by external mechanical restraint when power is removed. Power and feedback wiring enter on side A through a single connector, which keeps the cable entry concentrated in one location. Length code B gives the motor a medium housing length within this frame size and supports a balanced combination of torque and installation depth.

A centering diameter of 110 mm aligns the flange with machine interfaces, and the output uses a keyway shaft for positive torque transmission. The primary shaft includes a shaft seal that helps limit contamination at the output face during normal machine operation. Bosch Rexroth assigns the unit frame size 090, placing it in the medium-power range of the series. No secondary shaft is provided on side B, which helps keep the rear of the motor compact and leaves more clearance for adjacent hardware. This layout is useful in installations where routing space behind the motor is limited.
