Product Description:

The MDD071A-N-030-N2S-095PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. As a motor for digital drive controllers, it turns controlled AC from an Indramat inverter into rotary motion for positioning and velocity loops in automated machinery. The 071 frame size and standard housing give the unit a compact footprint suited to packaging stations, pick-and-place axes, and small transfer modules where space and mass must be minimized. It is well suited to applications that require smooth acceleration, stable low-speed operation, and accurate response to changing command signals.

A machined centering shoulder of 95 mm keeps the stator concentric with a gearbox or adapter plate. When stalled, the windings hold 2.2 Nm of continuous torque, so the axis can support loads during dwell periods without thermal overload. In motion, the electromagnetic circuit reaches a rated speed of 3000 rpm, allowing direct coupling to 1:1 belt drives without excessive inverter frequency. Rotor balance is classified as standard, and the short A-length stator keeps copper mass low for quicker response during repeated start-stop cycles. Because the motor ships without a blocking brake, any vertical load must be secured by external clamping or active torque from the drive when power is removed.

For installation, power and feedback leads exit on Side B, and a threaded connector groups the phase conductors and protective earth in one plug. Position data returns through digital servo feedback, enabling high-resolution closed-loop control without separate encoders. The steel shaft uses a keyway interface to lock pulleys or couplings, and a molded shaft seal behind the front bearing helps block coolant splash and fine dust. The combined power and feedback arrangement keeps the motor interface compact and makes external cable routing more straightforward. A single drive-side shaft end keeps the mechanical layout simple and leaves the opposite end free of extra output hardware.
