Product Description:

The MDD071B-N-030-N2T-095PR1 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a permanently excited AC motor intended for pairing with digital drive controllers where closed-loop speed and position control are required for synchronized machine movement in automated equipment. Within automated assembly cells or packaging lines, the motor converts commanded electrical waveforms into precise rotary motion that can be synchronized with sensors, indexing tables, or gantry axes during repetitive production cycles. Its construction follows the same mechanical outline as other 071 frame units, so it fits machine spaces designed around this housing size and supports tighter axis spacing in multi-axis layouts.

Mechanical alignment is simplified by a centering pilot of 95 mm, which helps keep the motor concentric with adjacent gearheads or flanges. Under thermally steady conditions, the rotor can deliver 4.4 Nm of continuous torque at standstill without exceeding the permissible winding temperature. During motion, the drive can reach a rated speed of 3000 rpm. Position information is supplied by an integrated multiturn absolute encoder, and the control loops use digital servo feedback transmitted to the controller through the motor connector on the right side of the housing.

Dynamic stops are secured by a blocking brake capable of 3.0 Nm, so vertical axes can hold load when system power is removed. The output shaft uses a keyway interface and includes a shaft seal, which helps limit lubricant migration and keeps splash or dust away from the internal bearings. Within the compact 071 frame, standard balancing helps reduce vibration during operation. The single-cable connector style streamlines wiring and avoids the need for an external junction box, which helps keep the motor envelope compact around the connection area.
