Product Description:

The MDD090B-N-030-N2M-110PB2 synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Engineered for digital drive controllers, it converts commanded current into regulated rotary motion for automated machinery such as pick-and-place gantries, light machining centers, and packaging axes. Its B length housing gives the motor a compact installation footprint while still supporting the inertia and thermal capacity needed for repeated motion cycles. This arrangement suits closed-loop applications that need fast correction of load changes and repeatable path control.

At standstill the motor supplies a continuous torque of 7.2 Nm, allowing it to hold or slowly move loads without excessive heating. When energized at its rated frequency, it reaches a nominal rotor speed of 3000 rpm, so the axis can match common machine speeds without added gear reduction. A blocking brake inside the end bell provides 11.0 Nm of static holding torque during power loss. Position data are returned through Digital servo feedback (DSF), which gives the controller high-resolution information for accurate current, speed, and position regulation. Mechanical alignment is aided by the 110 mm centering diameter, and the cable connection exits on Side B through a sealed circular connector for straightforward routing.

An integrated multiturn absolute encoder retains position across power cycles, so the machine can recover axis location without a homing move after shutdown. A fitted shaft seal helps protect the front bearing area from coolant splash and airborne particles, and the sealed front end is useful where fine dust or liquid residue can reach the drive train. The motor uses frame size 090, placing it within a common dimensional class for this series. Standard dynamic balancing reduces vibration during operation, and the keyed shaft end provides secure torque transfer to couplings or pulleys.
