Product Description:

The MDD115C-N-030-N2M-130PB2 is an AC synchronous motor built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it provides closed-loop speed and position control in automated machinery. The model uses standard balancing so it can operate at rated speed without excessive vibration. A shaft seal protects the internal bearings, and the single shaft end connects to couplings or pulleys on the driven axis.

A centering diameter of 130 mm positions the motor accurately in a pilot bore to help maintain concentric alignment with the driven mechanics. Power and feedback conductors exit on Side B, and the plug-in connector interface allows cable connection without opening the enclosure. During idle holding or slow indexing, the motor can deliver a continuous standstill torque of 47.0 Nm, which supports demanding loads without overheating. Under rated excitation, it reaches a nominal speed of 3000 rpm, making it suitable for direct coupling to gearless axes that require high rotational speed. The size 115 housing with length code C sets the motor’s overall frame dimensions.

The integrated blocking brake provides 60.0 Nm of static torque to keep vertical or suspended loads stationary during power loss. Position data is captured by an integrated multiturn absolute encoder, and the signal is returned through digital servo feedback (DSF) so the drive can recover the exact shaft position after an interruption. Torque is transmitted through a keyed shaft, and the keyway helps prevent slippage between the shaft and coupled components during repeated start-stop cycles. This arrangement is useful in applications such as indexing tables and packaging stations, where accurate motion and secure load holding are both important.
