MDD071B-N-040-N2S-095PR2
The MDD071B-N-040-N2S-095PR2 is a brushless synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts current commands into regulated torque and speed for positioning axes and light-duty conveyors. Its brushless synchronous design supports responsive acceleration and predictable speed regulation when paired with a compatible controller. The motor is suited to compact machinery cells that require repeatable closed-loop motion and stable operation through frequent start-stop cycles.
At standstill, the motor can provide a continuous torque of 4.4 Nm, which supports static loading without exceeding the thermal limit of the winding. During motion, the rotor reaches a nominal speed of 4000 rpm, giving the axis a useful range for fast indexing and short travel moves. The spring-applied brake delivers 6.5 Nm of holding torque to keep the load secured when power is removed. A centering diameter of 95 mm helps align the motor on the machine interface, and the 071 frame size establishes the outer dimensions used by this motor. The centering shoulder also helps seat the motor squarely against a mating flange. The B length code adds winding depth and increases continuous power density within this frame family.
Cables exit on the right side through a single multi-pin connector, which helps keep wiring compact and reduces bending in the harness near the motor. This arrangement also helps keep the cable path clear of nearby machine elements in tight installations. Contaminant ingress is limited by the factory-fitted shaft seal, and the output shaft uses a keyway profile for positive mechanical coupling. Position feedback uses digital servo feedback, allowing the drive to read rotor position directly and maintain precise velocity control without an external encoder. Standard rotor balancing helps limit vibration during operation, and the housing outline remains suitable for tight servo bays.
