Product Description:

The MDD071B-N-060-N2S-095PR1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it delivers precise rotary motion in automated assembly, packaging, and material-handling equipment where accurate speed and position control are required. Frame size 071 and length code B set the motor’s physical envelope, while the standard housing and standard balancing help keep vibration low during repeated starts and stops. A standard shaft end without a side B extension allows direct coupling through a keyed hub and supports compact machine layouts.

At standstill, the rotor can deliver a continuous torque of 4.4 Nm, so the drive can hold or slowly index moderate loads without overheating. During motion, the winding design supports a nominal mechanical speed of 6000 rpm, enabling high-throughput cycles when paired with a matching Indramat drive. A blocking brake is fitted, and its static torque capacity is 3.0 Nm, so the axis can remain fixed when power is removed. Position and velocity are reported through Digital servo feedback (DSF), which gives the controller the rotor data needed for stable closed-loop operation. Operation in dusty or oily environments is aided by a shaft seal that limits ingress at the output coupling.

A centering diameter of 95 mm aligns the flange precisely to the machine frame for accurate mounting. Power and feedback are routed through a connector on the right side of the housing, which helps maintain cable clearance in compact cabinets and tight machine spaces. The output shaft uses a keyway, simplifying torque transmission to pulleys or gearboxes without relying on shrink-fit components. Standard balancing keeps residual vibration low at full speed, and the standard housing dissipates heat through natural convection, so no external cooling accessories are needed.
