Product Description:
The MDD112B-N-030-N2M-180PA3 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied for use with digital drive controllers in industrial automation equipment. The motor delivers commanded rotary motion where accurate speed control and consistent torque response are required. This makes it suitable for positioning axes, transfer systems, and other automated machinery that depends on repeatable motion.
The stator flange provides a centering diameter of 180 mm for repeatable alignment with gearboxes or machine frames. The B length code gives the motor its axial dimension, and it supports a continuous standstill torque of 17.5 Nm. When the drive excites the windings up to the nominal speed of 3000 rpm, this output can be maintained without derating under normal operating conditions. A factory-installed blocking brake supplies a holding torque of 60.0 Nm, so vertical axes can remain fixed when power is removed. The output shaft uses a keyway profile and is supplied without a side-B shaft end to conserve installation space.
The electrical interface is arranged on side A of the housing, so power and feedback cables exit in the same direction as adjacent drives. A sealed connector system mates to the cabling, and the standard housing includes a shaft seal to help block coolant or dust ingress during routine machine operation. Position data is generated by an integrated multi-turn absolute encoder and transmitted as digital servo feedback, allowing the controller to close both speed and position loops without external sensors. The motor has a frame size of 112, which fits common mounting patterns while keeping the housing compact. The rotor is dynamically balanced to the standard grade for smooth running and stable operation across the motor speed range.
