Product Description:

The Bosch Rexroth Indramat MDD025C-N-100-N2K-040MA0 is a compact synchronous motor in the MDD Synchronous Motors series. Built as a motor for digital drive controllers, it converts regulated current from the drive into precise rotary motion for small automation axes. By combining a high pole-pair density with lightweight rotor construction, the unit serves in pick-and-place heads, printed-circuit routing tables, and miniature spindle stations where rapid acceleration and exact position feedback are mandatory.

Under continuous load the rotor can deliver 0.90 Nm of torque while parked, indicating the electromagnetic force available to hold a static load in closed-loop mode. The mechanical top speed reaches 10000 min⁻¹, allowing fast cycle times when paired with a matching inverter. Accurate concentric mounting is assisted by the 40 mm centering diameter that aligns the flange to the machine frame. Power and feedback conductors exit on Side A, simplifying cabinet layout when multiple motors are mounted in parallel, and the single plug-in connector reduces wiring time during installation or service.

Inside the standard housing the rotor is dynamically balanced to the specified grade, and the size code 025 keeps mass low for lightweight gantries. Motion data is captured by an integrated absolute encoder, while the drive refines velocity information through resolver feedback, giving dual-channel position verification. Because the motor is supplied without a holding brake it relies on drive-generated torque for standstill security, a suitable choice where external clamps or gears already lock the axis. The keyed keyway shaft transmits torque directly to couplings, and the absence of a shaft seal cuts friction at high-speed runs. Length code C adds stack depth without providing a side-B shaft end, completing the mechanical outline.
