MDD065A-N-040-N5M-095GA0

The MDD065A-N-040-N5M-095GA0 is a compact synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Developed as a motor for digital drive controllers, it converts regulated current into precise rotary motion for automated tooling, pick-and-place axes, and light transfer stations. When installed, the motor couples directly to the mechanical load, minimizing external transmission parts and enabling tight closed-loop positioning through its internal feedback elements.

The mechanical profile centers on a 95 mm centering diameter that aligns the 065 frame size and the short “A” length code with standard mounting flanges. Dynamic output is defined by a continuous standstill torque of 0.8 Nm, while peak shaft speed reaches 4000 min⁻¹ for fast indexing moves. Rotor and housing are trimmed to a standard balancing grade, and the enclosure is also supplied in a standard housing style. Electrical interfaces leave the stator on Side A through a single Connector, simplifying cable routing inside compact machine envelopes. A fitted shaft seal blocks lubricant migration along the plain steel journal and maintains IP protection around the bearing set.

For drive coordination the motor transmits position data through Digital servo feedback (DSF), sourced from an integrated multiturn absolute encoder that counts revolutions without auxiliary batteries. The rotor is machined as a plain shaft, allowing backlash-free clamp couplings, and the assembly is delivered without a blocking brake so holding torque must be generated by the drive or external mechanics. These features, combined with the motor’s designation as a product for digital drive controllers, allow deterministic motion sequencing, quick homing after power cycles, and straightforward maintenance because feedback, power, and mechanical interfaces follow uniform Indramat conventions.
