MDD071B-N-040-N2T-095GL1
The MDD071B-N-040-N2T-095GL1 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a permanent-magnet AC servo motor intended for use with digital drive controllers, where it delivers precise velocity and position control to automated handling axes, packaging units, and machine-tool spindles. A blocking brake is integrated so vertical loads can be held when power is removed, and the standard housing keeps the motor compact for installations with limited space.
This model supplies a continuous standstill torque of 4.4 Nm, providing the sustained force necessary for accurate low-speed moves and static holding tasks. Under rated electrical frequency, the rotor can reach 4000 rpm, allowing fast indexing cycles in pick-and-place stations. A centering diameter of 95 mm fits common flange patterns for straightforward installation. The brake develops 3.0 Nm of holding torque, which is sufficient to keep moderate inertial loads from drifting after power is removed. Power and feedback cabling exit on the left side, and the motor uses a single connector that combines phase conductors, signals, and the brake circuit to reduce external wiring.
Position feedback is generated through digital servo feedback (DSF), giving the drive real-time rotor angle data at high resolution. An integrated multi-turn absolute encoder tracks shaft revolutions without battery support, which removes the need for homing moves after shutdowns. The output shaft is a plain shaft with a contact lip seal that helps keep lubricants in and contaminants out. Frame size 071 and length code B place the motor in the medium torque range of the series while maintaining a lightweight form factor for gantry or articulated arm installations. Internal standard balancing reduces vibration at speed, and the shaft seal also helps protect internal bearings from airborne coolant or dust.
