Product Description:

The MDD071B-N-040-N2S-095GL0 is a synchronous servo motor from Bosch Rexroth Indramat’s MDD Synchronous Motors series, intended to drive machine axes through a matching digital controller. Within automated cells, the motor converts regulated current from the inverter into rotary motion that can be coordinated with encoder feedback for positioning, velocity regulation, or contouring tasks in packaging, handling, and light machining equipment where repeatable axis response is required. Power and signal conductors plug into a sealed connector instead of fixed leads, which keeps the motor interface compact and allows cable routing to remain organized around crowded machine frames.

Its operating data suit closed-loop servo applications that require both steady torque and high speed. At standstill, the rotor can deliver 4.4 Nm of continuous torque, indicating the sustained load it resists without exceeding thermal limits. Under rated excitation, the shaft reaches 4000 rpm, a speed useful for tooling spindles or pick-and-place actuators that demand rapid cycles. Rotor alignment during mounting is aided by a centering pilot of 95 mm. The feedback channel uses digital servo feedback (DSF), so the drive reads absolute position with one single-turn code word. Because the frame is supplied without a blocking brake, systems that require static holding torque must rely on drive torque or an external clamping device.

The rotor and fan are trimmed to a standard balancing grade, minimizing vibration even with the plain shaft used on this model. A durable shaft seal protects the bearing cavity and helps limit contamination around the bearings during normal machine operation. Cabling exits on the left side, so the installation needs clearance in that direction and benefits from a cable path that avoids tight bends near the housing. Size code 071 and length code B correspond to the stack geometry and thermal mass used by this motor. Those proportions support repeated motion cycles with a compatible digital drive in continuous industrial service.
