Product Description:

The MDD071B-N-030-N2S-095GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, it is intended to translate drive-level current commands into precise rotary motion in indexing tables, pick-and-place axes, and other automated assemblies that demand repeatable speed and position control. Internal rotor balancing is standard, and the motor uses a standard finned aluminum housing that dissipates losses generated during dynamic duty cycles.

This size-071, length-code-B unit delivers a continuous standstill torque of 4.4 Nm, providing the baseline holding force the axis can rely on when stationary while still energized. Under rated excitation, it has a nominal speed of 3000 rpm, so gearing and control loops can be set for moderate-speed point-to-point moves. The centering pilot on the mounting face measures 95 mm, and this dimension positions the motor concentrically in the machine frame while supporting runout accuracy. Power and feedback conductors exit on side B, which can simplify cable routing when space behind the load shaft is available. Electrical terminations are completed through a single keyed connector, allowing quick connection without rewiring individual cores.

Feedback data are returned through an integrated digital servo feedback (DSF) encoder that communicates absolute rotor position to the drive, eliminating the need for homing routines after power is restored. The shaft is a plain shaft, so couplings or pulleys can be mounted without keyways when low-vibration transmission is required. Contaminant ingress at the bearing journal is limited because the design is supplied with a shaft seal. Mechanical holding force during power-off is not provided because the motor is specified without a blocking brake, so external clamping devices or drive-torque holding strategies must be used when static load support is mandatory.
