Product Description:

The MDD071C-N-030-N2T-095GB0 is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Intended as a motor for digital drive controllers, it provides closed-loop speed and position control on mid-range machine axes. The unit corresponds to motor size 071 and length code C, giving a compact frame that fits drive systems with limited installation space. A standard housing and plain shaft arrangement simplify mounting, while the centering pilot and shaft end are matched to common couplings used in industrial automation. This layout suits positioning tasks that need repeatable motion without requiring a large motor envelope.

At standstill the motor can deliver a continuous torque of 6.6 Nm, enabling it to hold or slowly index loads without overheating. When operated at its nominal speed of 3000 rpm, the electromagnetic design keeps torque ripple low so velocity control remains precise. Accurate mechanical alignment is possible because the front flange offers a centering diameter of 95 mm, matching standard mounting pilot diameters on compact gearboxes. Rotor position is reported by an integrated multi-turn absolute encoder, and its signals are transmitted to the drive through digital servo feedback (DSF), allowing position tracking over multiple revolutions without battery support. Power and feedback conductors terminate on a rear-mounted connector, which keeps the connection point away from the mounting face and helps maintain a compact front profile.

Cables enter on side B, keeping the load side of the shaft clear. The motor is supplied without a blocking brake, so position during power loss must be maintained by external holding hardware or drive torque. Contaminant ingress is limited by a shaft seal, and the rotor is dynamically trimmed to a standard balancing grade, permitting direct coupling to low-vibration machinery. The shaft end is supplied without a side-B extension, and the plain shaft geometry supports backlash-free clamp couplings.
