Product Description:

Bosch Rexroth Indramat builds the MDD025B-N-100-N2K-040FL1 as part of the MDD Synchronous Motors series. This compact rotary motor serves as the mechanical output element on digital drive controllers that regulate precise speed and torque loops in automated assembly stations, semiconductor handlers, and light gantry axes. By combining a high base speed with a low-mass rotor, the unit supports fast indexing moves while maintaining reliable position feedback for coordinated multi-axis motion. That makes it suitable for handling processes that require short cycle times and repeatable acceleration profiles.

The motor develops a continuous standstill torque of 0.60 Nm, giving it enough holding capacity for small linear stages without overheating under rated current. This output suits light-duty positioning tasks that must maintain stable holding force during short pauses in motion. A nominal operating speed of 10,000 rpm allows direct coupling to high-speed tool spindles or feeders without intermediate gearing, which helps reduce drivetrain complexity. Power and feedback connectors are oriented to the left side of the housing, simplifying cable routing in tight cabinets, and the interface uses a keyed industrial connector for secure attachment. Rotor position is monitored by an integrated absolute encoder, so the drive acquires the electrical angle immediately after power-up without a homing move.

When motion stops, a blocking brake supplies 1.0 Nm of static torque to secure suspended loads and prevent drift during power loss. The flange centering pilot measures 40 mm in diameter, providing a precise seat that limits radial runout, and overall balancing remains at the standard grade used in the series. For applications that use analog sinusoidal signals for drive-based interpolation, the motor provides resolver feedback. A plain shaft permits rigid clamping couplers, and the lack of a shaft seal reduces friction for high-speed duty while the enclosure provides protection against external contamination. This shaft arrangement is suitable for clean installations where external sealing at the coupling is not required.
