MDD071B-N-040-N2S-095GR0
The MDD071B-N-040-N2S-095GR0 belongs to the MDD Synchronous Motors series from Bosch Rexroth Indramat. It is a brushless AC servo motor intended for use with digital drive controllers, where it provides closed-loop torque and speed control for positioning tables, pick-and-place axes, packaging modules, and other automated machinery. Its operating concept pairs the motor with electronic feedback so axis motion remains stable during acceleration, deceleration, and low-speed holding. The compact housing suits multi-axis installations, and factory balancing keeps mechanical vibration within normal limits during repetitive starts, stops, and direction changes in general industrial service.
The unit delivers a continuous standstill torque of 4.4 Nm, allowing drives to maintain static loads without additional gearing when the axis remains energized. A nominal speed of 4000 rpm is the synchronous operating point that the controller can command during cyclic motion profiles. The front flange has a centering diameter of 95 mm, which aligns the motor concentrically with gearboxes or machine frames and helps minimize runout at the coupling. Power, feedback, and brake conductors exit toward the right side, an orientation that simplifies wiring when motors are installed in a mirrored layout along a gantry. Position and velocity data are returned through digital servo feedback, giving the drive high-resolution information for rapid correction of load disturbances.
The motor is supplied without a blocking brake, so holding torque must come from the drive or from external clamps when power is removed. A sealed connector provides the electrical connection, and a fitted shaft seal keeps lubricants inside the bearing cavity while excluding spray or airborne dust in typical machine environments. The plain output shaft is ground to standard tolerances, and its plain shaft profile accepts custom hubs or couplings without a key or additional shaft machining. The size 071 frame and motor length code B provide a consistent external envelope for servo-axis layouts that use direct motor mounting.
