Product Description:

The MDD071B-N-030-N2L-095GB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and delivered within the MDD Synchronous Motors series. Intended for direct connection to digital drive controllers, it transforms commanded current into precise rotary motion for automated stations, packaging lines, and small machining centers. By integrating into closed-loop positioning systems, the motor enables repeatable axis control, smooth speed transitions, and consistent torque output across continuous industrial duty cycles.

At its rated operating point, the rotor turns at 3000 rpm, a synchronous speed that suits common AC drive frequencies while still allowing rapid acceleration commands. During standstill, the electromagnetic stack can sustain 4.4 Nm of continuous torque, allowing the axis to support static process loads without overheating. Power, encoder, and brake leads exit on Side B, so cabinet layouts can keep access on the opposite face. All conductors are gathered into a single keyed Connector, which keeps the connection secure and preserves sealing integrity. Rotor position is returned to the inverter through digital servo feedback, supplying high-resolution signals needed for tightly tuned velocity and position loops.

Mounting is guided by a centering pilot of 95 mm, which helps maintain repeatable alignment with the machine frame and minimizes radial runout. The motor is provided without a blocking brake, so holding torque during power-off must be supplied by the drive or by external clamps when required. Its Standard housing supports stable operation, and the motor balancing keeps vibration levels within ISO recommendations across the speed range. Stator length follows the B length code, adding active iron to raise continuous output compared with shorter stack variants while retaining the 071 frame size footprint. An internal shaft seal also helps protect the plain shaft from coolant splash and dust ingress.
