Product Description:

Bosch Rexroth Indramat manufactures the MDD090B-N-040-N2M-110GB1, a synchronous servo motor in the MDD Synchronous Motors series that pairs with digital drive controllers to deliver closed-loop motion in automated machinery. The model converts commanded drive current into rotary movement while supplying position data through internal feedback, making it suitable for packaging lines, pick-and-place axes, and other applications that demand repeatable speed and torque. Its feedback and motor characteristics allow the connected controller to regulate position, speed, and load response during continuous machine operation.

At the mechanical interface, the centering recess measures 110 mm, allowing direct seating into precision mounting flanges. When energized but not rotating, the rotor can maintain a continuous torque of 7.2 Nm, which is useful for steady static load conditions. During operation, the motor reaches a nominal speed of 4000 rpm, matching fast-cycle automation requirements. A blocking brake is fitted, and its holding capability is rated at 6.5 Nm to secure vertical or suspended loads at standstill. Rotor position is captured by an integrated multi-turn absolute encoder, enabling the controller to recover the exact shaft angle after power restoration without a homing cycle. The unit uses standard balancing for reduced residual vibration and is housed in the standard frame for this motor series.

Cabling enters on Side B through a sealed connector, so power and feedback conductors can be routed away from moving equipment. The output uses a plain shaft without secondary drive elements, making it compatible with clamp or collet couplings used in many machine designs. Servo loop data reach the drive over Digital servo feedback (DSF), helping maintain precise velocity control under changing load conditions. A compliant shaft seal protects the internal bearings from coolant spray and dust. Motor size 090 and length code B indicate the physical envelope used for this unit, which keeps the motor compact enough for responsive motion while preserving stable mechanical mounting.
