MDD071A-N-030-N2T-095GR0
The MDD071A-N-030-N2T-095GR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Built for digital drive controllers, it converts regulated three-phase current into precise rotary motion. This operating principle supports closed-loop speed and position control in pick-and-place modules, packaging stations, and general machine tool axes. The motor is intended for servo applications that require repeatable starts, controlled acceleration, and consistent positioning during cyclic motion.
Its continuous torque at standstill is 2.2 Nm, providing stable holding force under closed-loop current control. During motion, the rotor maintains a nominal speed of 3000 rpm, which suits common drive frequencies for mid-range positioning tasks. A centering diameter of 95 mm provides the pilot fit on the machine flange and keeps the stator aligned with the load coupling. Power and feedback leads exit on the right side through a single connector, which helps simplify cable routing in compact cabinets. The right-side connection keeps both cable groups at one outlet, which can help organize routing where machine space is limited. Contaminant ingress at the output journal is limited because a shaft seal is present, helping protect the bearing set during washdown or exposure to airborne coolant.
An integrated multi-turn absolute encoder reports rotor position across multiple revolutions, and the signal is transmitted through digital servo feedback (DSF) so the drive can close high-resolution position loops without external sensors. Absolute position data remains available over more than one revolution, which supports applications that cannot rely on a single-turn reference alone. The motor is supplied without a blocking brake, so any vertical axis using this unit must secure loads with an external brake or mechanical lock when power is off. Its architecture follows motor size 071, with a short axial length coded as A and standard balancing, which helps reduce reflected inertia during acceleration and supports accurate alignment in dynamic motion.
