Product Description:

The MDD071B-N-040-N2T-095PB2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for digital drive controllers and converts electrical input from a matched amplifier into controlled rotary motion for positioning, indexing, and process axes in automated machinery. In servo operation, the drive regulates phase current while the motor converts that command into predictable torque and speed. This makes the unit suitable for packaging, handling, and other automated equipment that depends on repeatable motion.

The unit attains a nominal speed of 4000 rpm, enabling rapid cycle execution when paired with compatible inverters. At standstill, it can deliver 4.4 Nm continuously, so it maintains torque for static load holding or low-speed creep without overheating. A blocking brake is mounted on the shaft, and its holding torque is 6.5 Nm for securing vertical or suspended loads when supply power is absent. Position data is provided by an integrated multi-turn absolute encoder, and the signal is transferred through the drive’s digital servo feedback (DSF) channel for closed-loop control. Because the feedback system tracks shaft position over multiple revolutions, the controller receives stable position information during changes in speed and direction. An internal shaft seal helps prevent oil or dust from entering along the output journal, and the power and feedback conductors terminate on a circular connector.

Cables exit on Side B of the housing, allowing routing away from machinery pinch points and leaving more space around the mounting face. A centering diameter of 95 mm aligns the flange with gearboxes or adapter plates, while the compact frame corresponds to motor size 071 and length code B. This combination keeps the installation compact while supporting the torque and speed characteristics expected from the motor platform. Rotor mass is balanced to the standard grade, the enclosure uses the series’ standard cast housing, and the single shaft end follows the standard design without a rear extension. Output torque is transmitted through a hardened keyway, which matches common hub connections and supports positive mechanical coupling to the driven load.
