MDD071B-N-030-N2S-095PR2
The MDD071B-N-030-N2S-095PR2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts controlled current from the drive into precise rotary motion for automated machinery. The unit belongs to length code B in the 071 frame class, so it is suited to applications that require repeatable torque and stable speed regulation. Built-in feedback allows the controller to maintain accurate position and speed control as operating loads change. This makes the motor suitable for automated axes that rely on consistent motion during repeated production cycles.
This motor uses a standard dynamic balance grade to limit vibration and has a centering diameter of 95 mm to align the flange with mating machine surfaces. Power and feedback conductors exit on the right side through a factory-mounted connector, which helps keep cable routing orderly in compact installations. At standstill, it can deliver 4.4 Nm of continuous torque without exceeding thermal limits, and it reaches a nominal speed of 3000 rpm when used with a matched inverter. Position information is returned by Digital servo feedback (DSF), allowing the controller to adjust current in real time. The rotor uses a keyway shaft with a single shaft end, so couplings and driven elements can be mounted in a conventional arrangement.
A blocking brake rated at 6.5 Nm is integrated to hold the load when power is removed, which is useful on axes that must remain in position at standstill. The motor size code is 071, placing it within the corresponding frame group for this motor series. The output shaft is supplied with a shaft seal, which helps protect the bearing area from contamination. The housing uses a standard design, and the motor is suitable for compact industrial installations that require closed-loop servo control. The integrated brake and feedback arrangement also supports controlled stopping and stable position monitoring during operation.
