Product Description:
The MDD071B-N-030-N2S-095PA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated current into precise rotary motion for automated axes. Typical tasks include indexing tables, pick-and-place heads, and light conveyor segments where fast response and repeatable positioning are essential. The motor follows the mechanical footprint common to the series, which helps it fit standard machine layouts and maintain alignment with the driven mechanism. Its synchronous design also supports consistent motion when the axis must accelerate, stop, and reverse frequently.
At stall, the windings can produce a continuous torque of 4.4 Nm, enabling stable force delivery for holding or low-speed feed duties without overheating. During standard operation, the rotor reaches a nominal velocity of 3000 rpm, giving adequate speed range for most medium-inertia loads tied to electronic gearing profiles. Accurate mounting is aided by a flange centering diameter of 95 mm, which helps maintain concentricity between the motor and a gearbox or coupling. A blocking brake integrated at the non-drive end supplies 6.5 Nm of static torque so vertical or suspended loads remain secure when power is removed. Closed-loop regulation is handled through digital servo feedback (DSF), which sends rotor position and commutation data back to the controller for stable speed control and accurate positioning.
Cabling exits on Side A, simplifying harness routing where several axes use a common connector direction. The shaft is machined with a keyway, allowing positive torque transfer to pulleys or spur gears without relying only on friction clamping. Frame designation 071 places the unit in the mid-size range of the series, supporting a balance of output and installation space in modular machinery. A fitted shaft seal helps limit dust and coolant ingress, which supports bearing protection when the motor is installed in semi-protected production areas.
