MDD071B-N-030-N2T-095PR0
The MDD071B-N-030-N2T-095PR0 is a servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Designed for pairing with digital drive controllers, it converts controlled current into repeatable shaft torque and speed so automated stations such as pick-and-place arms, feeders, and light machining spindles can execute programmed motions. A standard housing, standard dynamic balancing, and an internal shaft seal allow installation in enclosed cabinets while helping protect the bearings from dust and coolant splash during routine production cycles. This motor type is suited to applications that require precise acceleration, repeatable positioning, and stable speed control over frequent operating cycles.
Under rated electrical excitation, the rotor reaches a nominal speed of 3000 rpm, giving motion-control systems a predictable velocity reference that matches the 2-pole winding count and the inverter’s output frequency. At standstill, the stator can deliver 4.4 Nm of continuous holding torque, which is sufficient to support dwell periods without overheating. Mechanical centering during assembly is guided by a 95 mm pilot diameter, and all power and feedback plugs exit the right face because the connection direction is right. The frame uses size code 071, placing the motor in the mid-range of the series for applications with moderate inertia and compact machine layouts.
Position information is generated by an integrated multi-turn absolute encoder, which allows the controller to recover the rotor angle after power cycling and eliminates homing moves. Feedback signals leave the unit as digital servo feedback (DSF), providing high-resolution position data over a single shielded line and simplifying cable routing through machine conduits. Output torque is transferred through a keyed shaft, and the drive end uses a keyway profile while the opposite side remains closed to preserve rigidity. Because the motor is supplied without a blocking brake, any static load retention must be handled by the drive or by an external mechanical latch. This arrangement is suitable for axes that already use external holding devices or rely on controlled drive torque when stopped.
