Product Description:

Bosch Rexroth Indramat manufactures the MDD071C-N-030-N2S-095PL1 as part of the MDD Synchronous Motors series. This motor for digital drive controllers provides rotational power for axis modules, pick-and-place gantries, and other automation stages that require compact torque delivery at synchronous speed. Within the series, the C-length 071-frame model fits a mid-range power position and interfaces directly with Indramat drive amplifiers for closed-loop speed and position control. That arrangement suits automated equipment that depends on repeatable starts, stops, and short positioning moves in a compact installation space.

The motor delivers a nominal velocity of 3000 rpm, which is the synchronous operating point when the stator field is supplied by the matched inverter frequency. At standstill, it can supply 6.6 Nm of continuous torque without exceeding its thermal limit, supported by the standard housing conduction path and the C-length stator package. The rotor is finished to standard balancing quality so additional external counterweights are not required. A centering pilot of 95 mm supports precise flange alignment during installation. Service cables exit on the Left side through a connector. Power and feedback conductors share that keyed interface, which keeps the cable connection secure during operation. A fitted shaft seal helps block coolant or oil ingress, and the housing follows the standard enclosure pattern used for this motor line.

The integrated blocking brake arrests the rotor when power is removed and provides 3.0 Nm of static holding capacity for vertical loads carried by this frame size. Position reporting is furnished by digital servo feedback signals, giving the drive accurate commutation data without the need for an external encoder. Mechanical coupling is through a single-ended shaft with a keyway, and there is no side-B shaft extension. That layout keeps the output on the drive side only, which leaves the opposite end free of coupling hardware. The frame designation 071 keeps overall mass relatively low while preserving the stiffness needed for repeated acceleration and deceleration cycles.
