MDD071B-N-030-N2T-095GL1
The MDD071B-N-030-N2T-095GL1 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a motor for digital drive controllers used to generate continuous rotary motion in automated handling, packaging, and positioning equipment. The B-length frame and 071 size give it a mid-range form factor that pairs with compact servo drives in space-restricted machine frames. This layout supports closed-loop speed and position control on axes that must cycle repeatedly without using a larger motor housing.
The motor has a centering diameter of 95 mm, allowing accurate alignment against flanged gearboxes or mounts. At standstill, the rotor produces a continuous torque of 4.4 Nm, and it reaches a rated operating speed of 3000 rpm under nominal drive voltage and frequency. Rotor position is measured by an integrated multi-turn absolute encoder that reports the exact angle across multiple shaft revolutions, eliminating homing routines after power loss. All power, encoder, and brake lines are routed through a sealed connector on the left side, which simplifies cable routing when several axes are installed in series. Standard dynamic balancing minimizes residual vibration, and the housing has the series standard coating for general-purpose environments.
For static holding or emergency stops, the integrated blocking brake delivers 3.0 Nm of torque, keeping vertical or suspended axes in place when drive power is removed. Servo loop resolution is maintained by digital servo feedback, so the controller can regulate torque and velocity without additional sensors. The motor uses a plain shaft with a shaft seal to help prevent lubricant egress and protect internal bearings from dust or coolants. The motor is built without a side B shaft end, which reduces overhung mass and eases coupling to belt pulleys or pinion gears while preserving the standard enclosure integrity.
