MDD025A-N-100-N2K-040MA1
The MDD025A-N-100-N2K-040MA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical input into precise rotary motion for positioning and speed-regulated axes in automated machinery. The compact size code 025 and length code A allow installation in dense multi-axis assemblies where high acceleration and feedback accuracy are required. This compact format also suits light handling units and other space-limited equipment that benefit from fast motor response.
Its continuous torque capability at standstill is 0.33 Nm, which indicates the static torque available while the windings remain energized within thermal limits. When motion is commanded, the rotor can reach a nominal velocity of 10,000 rpm, supporting short mechanical time constants in pick-and-place units or small spindle duties. A blocking brake rated at 1.0 Nm is integrated to secure the axis during power loss or emergency stops. Position data are delivered by an integrated absolute encoder, so the control system can recover position after a restart without a homing cycle. The motor aligns concentrically through a 40 mm centering diameter, which helps it seat accurately on compact machine flanges.
Electrical and feedback links are routed on side A through a single connector, simplifying cable management in tight panels and reducing the number of separate connection points. Rotor mass distribution follows the standard balancing grade, minimizing vibration when the keyway shaft is coupled to lightweight loads. The motor uses a standard housing, and the shaft is delivered without a side-B extension to reduce overhang length. Because the assembly comes without a shaft seal, it is intended for clean, dry enclosures rather than washdown zones. A resolver feedback channel is also present, providing another source of coarse angle information alongside the absolute encoder.
