Product Description:

The MDD071A-N-040-N2T-095PR0 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded current into precise rotary motion for positioning or speed-regulated axes on automated machines and processing lines. In closed-loop operation, the motor supports repeatable motion on feed axes, indexing stations, and compact handling units. Its compact body suits installations where mounting space is limited but accurate response is still required.

This model delivers a continuous standstill torque of 2.2 Nm, allowing small to medium loads to be held without additional gearing. Its nominal speed reaches 4000 rpm for rapid cycle tasks. A centering diameter of 95 mm aligns the motor on the mounting pilot, and standard dynamic balancing reduces vibration during acceleration. Power and feedback are routed through a connector on the right side, which can simplify cable routing when the machine layout favors a right-hand exit path. The motor is supplied without a blocking brake, so holding during power-off must be provided by the drive or by external mechanics. The housing and shaft end are standard, and the A length with frame size 071 keeps the motor suitable for compact multi-axis layouts.

An integrated multi-turn absolute encoder reports position over the full rotation count, so the axis can retain position information after power cycling. Its signals are conveyed as digital servo feedback for direct closure of the position and velocity loops inside the controller. The output shaft uses a keyway to transmit torque to pulleys or couplings. It also has a shaft seal to help limit contaminant entry around the shaft area during operation near oil mist or coolant spray. This combination supports stable motion control where compact installation and dependable shaft coupling are both required.
