Product Description:

The MDD112D-N-030-N2M-180PB0 is a servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts regulated three-phase power into rotary motion for positioning and feed tasks in automated lines. The size 112 frame and D-length code provide a mid-range envelope that balances torque output with installation space. A standard housing encloses the stator assembly, supports convection cooling, and uses a centering pilot to simplify rigid flange mounting in compact machinery cells.

At standstill, the rotor produces 38.0 Nm of continuous torque, allowing direct coupling to many loads without secondary gearing. Under rated excitation, the motor reaches a nominal speed of 3000 rpm, providing consistent surface speed for cutting and transfer duties. Precise coaxial alignment is supported by a 180 mm centering diameter, and torque is transmitted through a shaft with a keyway that matches standard hub dimensions. The opposite face is supplied without an additional shaft end, which helps minimize overall length. Closed-loop regulation is achieved through Digital servo feedback (DSF), which sends high-resolution position data to the drive. Standard dynamic balancing helps limit residual vibration during rapid acceleration and deceleration.

High integration is provided by the motor’s integrated multiturn absolute encoder, which returns absolute position over multiple revolutions and removes the need for homing after power loss. All terminations exit on Side B through a sealed Connector, simplifying cable routing inside drag chains while helping protect the connection point from contamination. A shaft seal blocks lubricant splash and airborne particles, and the motor is supplied without a blocking brake, so static holding torque must be provided externally when required. This arrangement suits pick-and-place heads, indexing tables, and tooling spindles that require compact motor packaging and multi-turn position feedback.
