Product Description:

The MDD071B-N-030-N2T-095PA2 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for integration with digital drive controllers where compact rotary power and accurate positioning are required. By converting commanded current into proportional torque, the unit serves as the actuating element for feed axes, pick-and-place heads, and other motion tasks within automated assembly lines, packaging equipment, and machine tools. Its synchronous design supports controlled acceleration and repeatable motion in applications that depend on stable speed and position feedback.

In mechanical terms, the motor mounts through a flange with a centering diameter of 95 mm, which helps align the motor accurately with the driven machine housing. Its continuous torque at standstill of 4.4 Nm indicates the load it can hold indefinitely without exceeding permissible winding temperature. Under rated excitation, the rotor has a nominal speed of 3000 rpm, giving a predictable velocity ceiling for direct coupling to fast axes. All power, feedback, and brake leads exit on Side A, which can simplify cable routing in compact multi-axis layouts. Torque is transferred through a keyway shaft end, so couplings or pulleys can be locked positively without relying only on friction. This arrangement also supports secure mechanical connection where repeated starts, stops, and direction changes are common.

For applications that must prevent drift when power is removed, the blocking brake supplies a holding torque of 6.5 Nm, allowing vertical or cantilever loads to remain stationary. Position data comes from an integrated multi-turn absolute encoder, which records full-circle counts as well as completed revolutions. The drive receives high-resolution angle information through digital servo feedback, supporting precise closed-loop control during positioning and speed regulation. A dedicated shaft seal sits behind the front bearing to help keep dust, oil, and coolant out of the stator cavity. This added sealing helps protect internal components in machinery where contamination can collect around the motor face and shaft area.
