MDD025A-N-100-N2K-040FE0
The MDD025A-N-100-N2K-040FE0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is installed in light-duty industrial axes where rapid positioning and repeatable speed are required for automated assembly, semiconductor handling, or laboratory equipment. In these applications, the motor converts controlled current into precise rotary motion for small transport slides, indexing units, and pick-and-place mechanisms. Its size 025 stator and short A-length housing keep moving mass low, which helps when the axis must reverse quickly without adding unnecessary inertia.
This model supplies a continuous standstill torque of 0.33 Nm, giving small fixtures enough holding force during low-speed interpolation and short pauses between moves. Under rated conditions, the rotor reaches a nominal speed of 10,000 rpm, allowing short cycle times in compact handling heads and other high-speed mechanisms. A centering diameter of 40 mm matches standard flange patterns so the motor can seat firmly without additional adapters. All power and feedback leads exit on the left side, and the factory-fitted connecting cable with a coupling unit removes the need for separate field terminations. Standard dynamic balancing keeps vibration within normal limits during rapid motion and supports smooth running in compact multi-axis assemblies.
Position data comes from an integrated absolute encoder, while the built-in resolver feedback supports reliable commutation at high speed. Because the unit is supplied without a blocking brake, external holding methods are required when vertical loads are present or when the axis must stay fixed after power is removed. The housing uses the series' standard vented construction, and the shaft seal is omitted to reduce friction in clean, dry environments where washdown protection is not required. The motor uses a plain shaft for coupling without keyways, and the standard side-B closure removes the need for through-shaft hardware.
