Product Description:

The MDD071B-N-040-N2S-095GA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it works with compatible drive platforms to deliver precise speed and torque control. The motor is used in automated assembly stations, gantry axes, and material-handling lines where repeatable rotary positioning is required under closed-loop electronic control. This type of control allows the drive to correct position error during changing loads and frequent start-stop motion.

It delivers a continuous standstill torque of 4.4 Nm, allowing moderate load support without overheating when the shaft is locked. Dynamic moves are supported by a nominal speed of 4000 rpm, which allows fast axis response in positioning applications. A blocking brake is integrated, and its release torque is rated at 3.0 Nm, so the axis remains mechanically secured during power loss. Servo feedback is provided through digital servo feedback, which sends position data to the controller for stable velocity and position regulation. Electrical and signal cables leave the housing on Side A through a sealed circular connector, which helps keep cable routing compact. The motor centers on a 95 mm pilot diameter, giving repeatable coaxial alignment to gearbox flanges or mounting plates.

The rotor interface uses a plain shaft with a factory-fitted shaft seal that helps block lubricant migration while tolerating light spray. Mass distribution is kept uniform through standard balancing, which helps limit vibration when the motor is coupled to flexible couplings. The motor has a frame size of 071, and the B length code gives additional active stack depth without increasing the housing diameter. A standard housing with natural cooling fins encloses the stator, and the shaft end is provided only on the drive side, which helps keep the overall motor length shorter and leaves no extension on side B.
