Product Description:

The MDD071B-N-030-N2S-095PB2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it serves as the electromechanical link between the inverter and the mechanical load in industrial automation lines. By converting three-phase stator current into tightly regulated torque and speed, the unit gives packaging stations, pick-and-place axes, and indexing tables the position accuracy required for repeatable production cycles. Its synchronous design also supports responsive acceleration and stable low-speed control when paired with a compatible controller.

At a nominal speed of 3000 rpm, the rotor can maintain a constant cycle rate when supplied with the rated frequency from the companion inverter. During standstill, it can deliver 4.4 Nm continuously, allowing the motor to hold load without excessive heat buildup. For short braking or indexing events, the blocking brake applies 6.5 Nm so the shaft remains fixed after power is removed. The centering shoulder measures 95 mm, providing a locating surface that aligns the motor with gearbox or machine interfaces and helps limit runout. Position accuracy is enhanced by the integrated digital servo feedback (DSF) encoder, which supplies high-resolution speed and position information to the controller. This feedback helps the drive maintain smooth speed regulation and repeatable stopping points during cyclic motion.

The electrical connection is made through a sealed connector located on Side B, keeping cables clear of the drive end and simplifying routing in compact machine layouts. The motor uses standard balancing to reduce vibration during rotation. Frame classification 071 and length code B identify the stator stack dimensions associated with the motor’s size and thermal mass. The motor is delivered with a shaft seal to help reduce the entry of coolant or dust, and the single output shaft is machined with a keyway so torque can be transmitted to pulleys or couplings. A standard housing and the lack of a secondary shaft end simplify mounting where space behind the motor is limited.
