MDD025B-N-100-N2K-040FL0
The Bosch Rexroth Indramat MDD025B-N-100-N2K-040FL0 is a compact synchronous servo motor in the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts DC bus power into precise rotary motion for light pick-and-place axes, small assembly stations, and other high-speed positioning duties. The model uses the 025 frame size and the B length magnetic stack, giving the motor a short overall body that fits inside tight mechanical envelopes while still delivering closed-loop performance. Its compact format suits automation axes where installation space is limited and repeatable positioning is required.
The motor has a continuous standstill torque of 0.60 Nm, which indicates how much load the rotor can hold indefinitely without exceeding thermal limits. Rated speed reaches 10000 rpm, enabling rapid cycles where high shaft velocity is essential. A centering diameter of 40 mm aligns the housing concentrically on the mounting pilot. Cables leave the motor through a keyed connector on the left side, simplifying routing in multi-axis machines. The built-in integrated absolute encoder reports the exact rotor position immediately at power-up, supporting homing-free operation. Standard dynamic balancing is applied to the rotor to keep vibration within permissible limits during acceleration.
Position information is available as absolute feedback at startup, so the axis can be referenced without a separate homing routine. The rotor is supplied without a blocking brake, so any power-off holding force must come from external clamping devices or the drive itself. A hardened plain shaft is provided without a secondary shaft end or shaft seal, so the standard housing should be installed in clean, splash-free zones. The absence of a shaft seal reduces friction and is better suited to dry areas with controlled contamination.
