Product Description:

The MDD071A-N-040-N2T-095GL1 is a servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it delivers closed-loop rotary motion to axes that require repeatable speed and position control in automated machinery. Its compact 071 frame size and A length code make it a practical choice for packaging lines, pick-and-place units, and light tooling spindles. This layout supports installations where responsive motion, compact dimensions, and accurate feedback are all required in the same axis package.

Its centering diameter of 95 mm provides a locating surface for accurate coaxial mounting to adjacent mechanical components. Power and feedback cables exit on the left side through a sealed connector, which helps when space around the motor is limited. At standstill, the motor can deliver a continuous torque of 2.2 Nm, allowing it to maintain load without excessive thermal stress during constant current operation. Position information is supplied by an integrated multi-turn absolute encoder, so the controller can recover shaft angle after power loss without an external homing routine. An integral blocking brake generates up to 3.0 Nm of static torque, which helps keep vertical or suspended loads from drifting when the drive is disabled.

During motion, the rotor can track speed commands up to 4000 rpm, matching applications that combine quick indexing with smooth constant-speed operation. Commutation and servo loop closure rely on Digital servo feedback (DSF), which provides the drive with high-resolution data for stable velocity and position control. The drive end uses a plain shaft that connects directly to couplings or timing pulleys. Contamination ingress is limited by a design supplied with a shaft seal, and the standard housing supports use in general machine layouts where dependable rotary performance is needed over repeated operating cycles.
