Product Description:

The MDD071A-N-040-N2S-095GR2 is a synchronous servo motor developed by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a compact drive element for digital drive controllers, the unit converts regulated current from the inverter into mechanical rotation for positioning axes, feed drives, or auxiliary spindles in automated machinery. Servo position data is returned through digital servo feedback, enabling the controller to close a high-resolution velocity and position loop.

The motor seats against a mounting pilot that has a centering diameter of 95 mm, which aligns the stator to the machine frame and minimizes radial runout. Power and feedback lines exit on the right side, matching installations that require right-side cable routing. At standstill, the electromagnetic system can supply 2.2 Nm of continuous torque, providing stable holding force without overheating under rated cooling conditions. The rotor can maintain production speeds up to 4000 rpm, supporting fast cycle rates on indexing tables or pick-and-place axes. Mechanical proportions correspond to size 071, so the flange pattern matches other 71 mm frame motors in the series.

The integrated blocking brake delivers 6.5 Nm of torque, allowing vertical loads to remain secure when the inverter is disabled. A shaft seal surrounds the plain shaft to limit lubricant migration and protect the interior from fine dust or coolant spray, complementing the standard housing and standard balancing grade on the rotor. The stator stack follows the A length code, giving a shorter body that reduces mass in moving-gantry applications while still accepting the connector-based power interface used for this product type. The shaft lacks a side B extension, simplifying coupling alignment, and the plain journal end is suitable for clamp or collet hubs without keys.
