MDD071A-N-030-N2T-095GR1
The MDD071A-N-030-N2T-095GR1 is a synchronous servo motor built by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for use with digital drive controllers, it provides electrically commutated torque for positioning and feed axes in machine tools, packaging lines, and other automation systems. Its synchronous design supports fast response, stable low-speed operation, and repeatable motion during closed-loop control. This type of motor is used where the drive must accelerate and decelerate an axis precisely while maintaining consistent feedback to the controller.
A centering diameter of 95 mm aligns the motor on mounting flanges while helping maintain concentricity with the driven load. Power and feedback connections exit on the right side, and the single-cable interface uses a keyed connector for a secure connection in tight machine spaces. At standstill, the rotor can deliver 2.2 Nm continuously without exceeding thermal limits, which supports static holding and low-speed creep functions. The motor has frame size 071 with length code A, which keeps inertia low for responsive axis movement. Position data are provided by an integrated multi-turn absolute encoder, so the controller can track shaft position over multiple revolutions without a homing routine after startup.
For power-off conditions, the motor includes a blocking brake rated at 3.0 Nm, which helps secure vertical or inclined axes when motion must stop. Feedback is handled through Digital servo feedback (DSF), which works with compatible drive amplifiers for current, speed, and position control. The rotor reaches a nominal speed of 3000 rpm during normal operation. The motor also uses a plain shaft with an integral seal and a single-ended shaft arrangement, so there is no shaft extension on side B. The sealed shaft area supports general industrial use where light contamination may be present around the drive end.
