Product Description:

The MDD025B-N-100-N2K-040FF1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for operation with digital drive controllers that demand fast response and compact form factors in industrial automation. By supplying controlled torque and speed, the motor drives small positioning tables, feeders, or auxiliary axes while allowing closed-loop control through its integrated absolute encoder and resolver feedback. A blocking brake is fitted to secure the load whenever the controller removes power.

The motor has a nominal rotational speed of 10,000 rpm, enabling rapid cycle times in lightweight actuation tasks. At standstill, the electromagnetic structure can deliver 0.60 Nm of continuous torque, which is sufficient for maintaining position or applying gentle forming forces without thermal overload. For safety during power-off, the integrated blocking brake supplies 1.0 Nm of holding torque, keeping the shaft fixed against back-driving loads such as vertical carriages. Position and velocity information is produced by the motor’s resolver feedback, a sensor that outputs analog sine-cosine signals to the drive so that commutation and motion control retain full resolution even at the highest operating speed.

The mechanical layout supports straightforward installation. A 40 mm centering diameter aligns the front flange with gearboxes or mounting plates, while standard balancing keeps vibration within ISO limits at the stated speed range. Power and sensor conductors enter via a connecting cable with coupling unit, and this right-side connection keeps routing consistent in multi-axis cabinets. The output element is a plain shaft, suitable for clamp or press-fit couplings, and it is delivered without a shaft seal, so the motor should be placed in environments where fluid ingress is not expected.
