Product Description:

The MDD071A-N-030-N2T-095GA2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts electrical commands into controlled rotary motion for positioning and velocity tasks on automated machinery. This model uses motor size 071 and the compact A length code, so it fits installations that need a short motor body without giving up closed-loop servo operation. It comes in a standard housing with standard dynamic balancing, and a shaft seal is fitted to help limit contaminant ingress during continuous industrial duty.

The motor has a centering diameter of 95 mm, which seats the unit accurately in gearbox or machine flanges. Power and feedback conductors exit on side A through a single connector, allowing service access from one direction and helping reduce cable loops inside the cabinet. Under stalled conditions, it can supply 2.2 Nm of continuous torque, which supports steady holding force on axes that must resist external loads without overheating. During motion cycles, the rotor reaches its nominal speed of 3000 rpm, matching the operating range commonly used with digital servo controllers.

Closed-loop positioning is handled by an integrated multi-turn absolute encoder and digital servo feedback (DSF), so the drive receives position data without requiring a homing sequence after power loss. A blocking brake rated at 6.5 Nm engages when the axis is disabled, helping prevent drift on vertical or suspended loads. The mechanical interface uses a plain shaft without a side-B extension, allowing couplings to mount flush with the front face while maintaining axial alignment. That arrangement is useful on machines that must restart with known position data already available to the control system.
