MDD025B-N-100-N2K-040MB0
The MDD025B-N-100-N2K-040MB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a compact 025-frame unit, it serves digital drive controllers that require fast response in a limited footprint. In automated assembly cells, laboratory handling stations, and light conveyor zones, the motor converts commanded current into high-speed rotation so that small loads can be positioned quickly and repeatedly.
This model delivers a nominal speed of 10000 rpm, allowing actuators to cycle rapidly without gearbox multiplication. At standstill, it can apply 0.60 Nm of continuous torque, enough to maintain position against modest static loads while staying within the thermal limits of the standard housing. The flange registers to machinery through a centering diameter of 40 mm, which aligns the rotor axis and minimizes runout. Power and feedback leads exit on side B, simplifying cable routing when the drive cabinet is mounted behind the axis. A sealed connector interface replaces fixed glands, which helps prevent wiring errors and supports quick cable connection.
Position information is generated by resolver feedback, which withstands vibration and high rotational speed, while an integrated absolute encoder supplies multi-turn data for immediate homing after power-up. Because the motor is supplied without a blocking brake, vertical loads must be held by the drive or by an external mechanical lock during shutdown. The single-ended keyway shaft ensures positive coupling to pulleys or couplings, and it is supplied without a secondary shaft end or shaft seal to reduce length and friction. Standard dynamic balancing and the lack of additional seals help keep inertia low, which supports quick response to speed commands from the paired controller.
