MDD071B-N-030-N2S-095GR2
The MDD071B-N-030-N2S-095GR2 is a synchronous AC motor built by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is intended for use with digital drive controllers that provide controlled torque and speed in automated machine axes, packaging stations, and material-handling stages within industrial automation. By converting commanded current into repeatable rotary motion, the unit supports indexing tables, small conveyors, and auxiliary positioning axes that must follow programmed profiles with minimal lag. Its overall arrangement suits compact servo applications that require accurate starts, stops, and short positioning moves throughout repeated cycles.
The motor delivers a continuous torque at standstill of 4.4 Nm, allowing stable force output while the axis remains stationary and energized. During motion, the rotor reaches a nominal speed of 3000 rpm, which matches common operating conditions for responsive servo duties. The motor mounts into machine frames through a centering diameter of 95 mm, and the housing uses length code B. It also uses frame size 071, which keeps the package suitable for mid-range servo axes without excessive installation space. Position and velocity are returned to the controller through digital servo feedback (DSF), so closed-loop regulation can be maintained without an external encoder.
The integrated blocking brake delivers 6.5 Nm of holding torque, so a parked axis can remain locked when power is removed. The output uses a plain shaft with a shaft seal, and the rotor is supplied with standard balancing to help limit vibration at rated speed. Cable terminations use a right-hand mounted connector, which supports the stated connection direction without requiring a separate terminal housing. The housing uses the standard design, and the shaft end is provided only on side A for coupling to gearboxes or pulleys.
