MDD025B-N-100-N2K-040FF1
The MDD025B-N-100-N2K-040FF1 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a compact motor for digital drive controllers that supplies high-speed rotary motion to positioning axes in automated machinery. By combining an integrated absolute encoder with an internal blocking brake, the unit lets a controller read precise rotor angle data and hold load position when power is removed, making it suitable for pick-and-place gantries, small spindle drives, and lightweight robotic joints. Its compact format is useful where the motor must fit into dense machine layouts without giving up accurate feedback or holding capability.
The stator flange has a centering diameter of 40 mm, allowing accurate pilot fit to gearheads or machine plates. Power and feedback conductors exit on the right side, and the factory-installed connecting cable with a coupling unit can be disconnected without tools. At standstill, the motor develops 0.60 Nm of continuous torque, and the winding design supports a rated mechanical speed of 10000 rpm for rapid indexing cycles. The blocking brake can apply up to 1.0 Nm of holding torque, so suspended or vertical loads remain fixed after a controlled stop. A standard housing, a plain shaft end, and a B-length stator frame complete the mechanical layout.
Position data are transmitted through the integrated absolute encoder and are processed by the drive as resolver feedback, providing rotor angle information that remains available after power cycles. Because the shaft is specified without a shaft seal, the motor is best used in clean areas where splash and oil ingress are not expected. The rotor uses standard balancing, which helps limit residual vibration so the 025 frame size can run at full speed without placing unnecessary force on adjacent bearings. Stable rotation is especially helpful on small axes that use light couplings and fast acceleration profiles.
