MDD071B-N-040-N2S-095PR0
The MDD071B-N-040-N2S-095PR0 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with compatible digital drive controllers, the unit converts controlled current into proportional torque and speed for positioning axes, conveyors, and packaging equipment. Its compact housing and connectorized wiring simplify installation inside machinery. Because it is a synchronous servo design, it is suited for automated assembly, pick-and-place systems, and material-handling lines that require responsive motion and repeatable positioning.
The motor’s nominal velocity capability is 4000 rpm, so the rotor can respond quickly to changing motion commands without exceeding its intended operating speed. Under locked-rotor conditions, it provides 4.4 Nm of continuous standstill torque, which is useful when sizing the axis for steady holding demand. A centering flange diameter of 95 mm helps align the motor to mating components, and the output end is fitted with a shaft seal to help keep lubricant in place and reduce contaminant entry. Power and feedback cables exit on the right side, which can simplify routing in side-mounted machine layouts and other compact installations.
The shaft uses a keyway profile, allowing couplings or pulleys to transmit torque securely. Rotor position is reported through digital servo feedback, allowing the controller to maintain closed-loop velocity and position control with accurate signal processing. This feedback method supports precise motion response during repeated starts, stops, and short indexing moves. The compact mechanical envelope corresponds to size 071, which helps keep inertia and overall weight moderate for rapid acceleration cycles. The motor is supplied without a blocking brake, so holding force at standstill must be provided by the drive or an external mechanical device.
