MDD071B-N-060-N2T-095GR2
The MDD071B-N-060-N2T-095GR2 synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it uses frame size 071 with length code B, giving a compact and power-dense option for mid-range axes in assembly and general automation equipment. A standard housing protects the stator windings, and the shaft end is supplied in the normal configuration without a rear extension, making the unit suitable for inline couplings and belt transmissions often used in automated cells. This layout also suits installations where limited rear clearance favors a direct connection to the driven load.
This model develops a continuous standstill torque of 4.4 Nm, allowing steady force output when the rotor is locked by the drive. Under rated excitation, the rotor reaches a nominal speed of 6000 rpm, so high-throughput positioning routines can be carried out without mechanical overspeed. A blocking brake rated at 6.5 Nm secures the load when power is removed, and an integrated multi-turn absolute encoder provides position data over multiple revolutions for closed-loop control. Installation is centered with a 95 mm pilot diameter that matches standard servo flanges, ensuring repeatable alignment to gearboxes or machine frames. The encoder and brake arrangement supports controlled stopping and accurate position recovery after power returns.
Dynamic balance follows a standard grade, which helps minimize vibration at high speed. Power and feedback connectors exit on the right side, which can simplify cable routing in cabinets that open from the left. All terminations are made through a single keyed connector, and position signals are returned through digital servo feedback (DSF) for compatibility with matching drives. A fitted shaft seal protects the bearings from coolant splash, and the drive end uses a plain shaft so couplings can seat directly without keyways or tapers. This shaft style works well with friction-locked couplings that depend on accurate concentric seating.
