Product Description:

The MDD071B-N-060-N2T-095PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as the rotary element in digital drive controllers, generating commanded motion for automated assembly and material-handling stations. The 071 frame size combined with the B length code gives this model a narrow footprint while supporting efficient use of rotor inertia. Its electromechanical design targets installations that need rapid speed changes without sacrificing positioning accuracy. The motor is suited to coordinated servo axes in transfer systems, indexing devices, and compact handling units where repeatable motion is required throughout frequent start-stop cycles.

At the core of its operating range is a nominal speed of 6000 rpm, permitting fast indexing cycles. Continuous torque at standstill reaches 4.4 Nm, so the axis can hold loads during dwell periods without extra gearing. Power and feedback leads exit on Side B, where a single industrial connector handles both phases and signals, reducing cabinet depth. Position data is returned through digital servo feedback (DSF) generated by the integrated multiturn absolute encoder, allowing the controller to track revolutions even after power loss. The housing is supplied in the standard enclosure style, and the motor carries a shaft seal that blocks coolant and dust from the bearing chamber. This feedback arrangement also supports accurate restart behavior because the controller receives position information without relying on a separate external sensor package.

A blocking brake rated at 3.0 Nm is fitted to secure the axis when the drive is disabled, which is useful on vertical or suspended loads. Mechanical alignment to gearboxes or flanges is guided by a centering pilot of 95 mm, while torque transfer occurs through a keyway shaft that accepts standard keyed couplings. Rotor mass is trimmed to meet Standard balancing class, allowing the unit to spin at full speed with low vibration. The shaft end on the drive side follows the standard geometry, and no shaft extension is provided on the opposite face, simplifying sealing with the installed shaft seal. This layout helps the motor fit directly into common gearbox and coupling arrangements while keeping the overall mechanical package straightforward.
