MDD071A-N-040-N2T-095PL1
The MDD071A-N-040-N2T-095PL1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers. It is intended to generate controlled rotary motion in compact industrial axes that demand precise position feedback, repeatable response, stable torque at low speed, and accurate behavior during frequent start-stop cycles.
The motor delivers a continuous standstill torque of 2.2 Nm, giving small pick-and-place stations or auxiliary spindles a predictable mechanical holding force under rated current. Its rotor can reach a nominal speed of 4000 rpm, so cycle times remain short when acceleration profiles are aggressive. Position data are supplied by an Integrated multiturn absolute encoder working with Digital servo feedback (DSF), which removes the need for external homing routines after power loss. Shaft concentricity is referenced to a centering diameter of 95 mm; that dimension aligns the housing in standard machine mounts and works with the motor’s standard balancing to minimize vibration. A fitted shaft seal helps protect internal bearings from contamination, and the housing uses the standard series style without an added surface cooling channel.
The unit ships with a blocking brake that applies 3.0 Nm of static torque, preventing back-drive on vertical loads when power is removed. Power and feedback lines are routed through a connector located on the left side of the stator, matching cable trays that enter the enclosure from that direction. A keyed output shaft with a keyway accepts couplings or pulleys without slip, and the single-ended shaft leaves the opposite end free of auxiliary extensions. Motor size 071 and length code A keep the package compact for small-axis layouts.
