Product Description:
The MDD071B-N-040-N2T-095PR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, it serves as the rotary actuator in automated packaging lines, pick-and-place modules, and general positioning stages where dynamic, closed-loop motion is required. Position feedback is provided by an integrated multiturn absolute encoder, and control signals are returned through digital servo feedback, enabling precise commutation without external sensors. That arrangement lets the connected drive monitor rotor position continuously and respond quickly to load changes during acceleration, deceleration, and holding.
The motor is factory-balanced to the standard grade, so additional coupling compensation is unnecessary during installation. This helps reduce vibration transfer to connected components during repetitive motion. Its centering diameter of 95 mm provides the pilot fit that aligns the flange with machine frames. At standstill it can deliver 4.4 Nm of continuous torque, a capacity suited to medium-payload indexing. The nominal mechanical speed reaches 4000 rpm, allowing fast cycle times when paired with a matched inverter. A blocking brake is included and supplies 6.5 Nm of static holding torque to secure vertical axes during power loss. A shaft seal is fitted to protect the standard housing against oil splash, and the power and feedback lines terminate through a single circular connector.
For cabinet wiring, the connector is oriented to the right, which can simplify harness routing along machine sidewalls. The motor belongs to size code 071, and its length designation B refers to the active stack height inside the stator. A keyed shaft specified as keyway permits positive torque transfer to pulleys or couplings, while the absence of a side-B shaft end keeps the rear housing clear for the brake and encoder components. This layout leaves the rear section dedicated to internal components instead of a second shaft extension.
