MDD071C-N-030-N2L-095GB0
The MDD071C-N-030-N2L-095GB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for mounting on digital drive controllers, it delivers closed-loop motion so automated plant equipment can position loads accurately at commanded speed and torque setpoints. Its construction follows the standard housing and balancing arrangement used for medium-frame machine axes that require consistent dynamic response.
This model supplies a continuous standstill torque of 6.6 Nm, allowing drives to hold static loads without excess heating. During operation it reaches a nominal speed of 3000 rpm, which works with electronic commutation to maintain steady shaft velocity under varying load. The centering pilot diameter is 95 mm, providing accurate mechanical alignment with gearboxes or flanges, while power and feedback leads exit on Side B so cabinet layouts can keep cables on the non-drive end of the machine. A keyed circular connector is the designated connection type, simplifying cable attachment. Length designation C identifies the stator package depth associated with the motor’s thermal capacity and inertia. Standard balancing limits residual vibration at rated speed, and a fitted shaft seal blocks oil or dust at the motor-to-machine interface. Because the plain housing is uncooled, heat dissipation relies on convection across its aluminum frame.
The motor has a frame size of 071, giving a stator diameter suited to compact handling modules. The output end is a plain shaft, and the opposite end is closed, eliminating side-B overhang loads. The motor is supplied without a blocking brake, so vertical axes must use external holding devices if power-off retention is required. Position data is returned through digital servo feedback (DSF), enabling the drive to use high-resolution control loops without additional sensors. A sealed housing and shaft seal protect internal laminations from coolant splash and airborne contaminants.
