Product Description:

The MDD071B-N-060-N2T-095GL1 is a synchronous AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated current from an Indramat drive into mechanical rotation for positioning axes and feed spindles in automated machinery. Its compact frame and integrated feedback support closed-loop control at the axis level, making it a common actuator in multiaxis machining centers and material-handling stations where repeatable speed and position are critical.

The motor reaches a nominal velocity of 6000 rpm, allowing high surface speeds on small mechanical transmissions. At standstill, it can deliver 4.4 Nm of continuous torque, so static holding and low-speed indexing can be maintained without overheating. A centering diameter of 95 mm aligns the housing precisely in flange mounts and helps keep radial runout within tolerance. Power and feedback conductors exit on the left side through a sealed connector, simplifying cabinet routing when several axes are installed in parallel. Command information is returned to the drive over digital servo feedback (DSF), enabling real-time current and position loops without a separate resolver interface.

Position data is generated by the integrated multiturn absolute encoder, so homing routines are unnecessary after power cycling. For vertical axes, the built-in blocking brake supplies 3.0 Nm of holding torque to help prevent drift when the drive is disabled. The output interface is a plain shaft with a shaft seal, allowing pulleys or gearwheels to be coupled while helping keep lubricant inside the gearbox. The motor has size 071 with the B length code, and standard balancing helps limit residual vibration as the rotor accelerates toward top speed. This combination of feedback, brake, and shaft sealing supports accurate motion in tightly packaged machine layouts.
