MDD071A-N-030-N2S-095GR2
The MDD071A-N-030-N2S-095GR2 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is supplied for use with digital drive controllers, giving closed-loop motion control in automated handling modules, packaging lines, and other equipment where compact rotary actuation is required. Its slotless stator and rare-earth magnets support steady torque across the working speed range, while the integrated commutation encoder sends position data directly to the drive electronics. This arrangement supports smooth low-speed response and accurate synchronization with commanded motion profiles during repeated machine cycles.
The motor develops a continuous standstill torque of 2.2 Nm, allowing it to hold or index light mechanical loads without overheating. Its nominal speed is 3000 rpm, which is the rated operating point where velocity regulation remains stable under load changes. Feedback is handled by Digital servo feedback (DSF), so the controller receives high-resolution rotor angle data for precise positioning and repeatable speed control. Power and signal conductors exit on the right side, which supports orderly cable routing in cabinets arranged with horizontal motor rows. A circular industrial connector provides a keyed, vibration-resistant connection for the drive and encoder leads during continuous production cycling.
Dynamic braking is supported by an internal stopping device that can apply 6.5 Nm of holding torque when power is removed, which helps prevent uncommanded motion on vertical axes. The motor seats against centering shoulders machined to 95 mm for repeatable alignment on gearbox flanges, and the mechanical frame follows size code 071. The output uses a plain shaft, which works well with clamp collars or shrink disks in compact drive trains. The unit also includes standard balancing, a shaft seal against oil mist, and a single-ended shaft design. These features support stable mechanical integration in machines that require accurate rotary motion and compact motor mounting.
