Product Description:

The MDD112B-N-030-N2M-130GA0 is an AC synchronous motor built by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. The unit converts electrical input from the drive into controlled rotary motion for positioning, indexing, and speed-regulated tasks on automated machine axes. Its frame code 112 and length code B place it in the mid-range of the series, balancing torque output with installation space. Its synchronous design allows the paired controller to maintain consistent response during acceleration, deceleration, and dwell periods. This layout makes the motor suitable for packaging machines, transfer lines, and material-handling equipment that require accurate cyclic motion.

Continuous torque at standstill reaches 17.5 Nm, allowing the axis to hold load without overheating when motion is paused. During operation, the rotor can reach a nominal mechanical speed of 3000 rpm, supporting fast cyclic movement on automated axes. Position data is delivered by an integrated multi-turn absolute encoder, which reports both revolution count and angular position, while digital servo feedback (DSF) supports stable speed regulation. This feedback arrangement helps the drive track commanded motion with consistent accuracy during repeated cycles. The motor is supplied without a blocking brake, so power-off holding force must be provided by the external mechanism or by drive-generated torque.

A centering diameter of 130 mm aligns the flange to the machine frame, and service access is simplified because the power and feedback plugs are mounted on Side A through a keyed connector interface. This arrangement keeps cable routing concentrated at one end of the motor, which can simplify installation in compact machine spaces. The output uses a plain shaft with a factory-installed shaft seal, which helps limit lubricant migration and coolant ingress into the bearing chamber. Standard dynamic balancing minimizes residual vibration over the full speed range. The standard housing maintains thermal contact with the surrounding air, which supports steady heat dissipation during normal operation.
