MDD025B-N-100-N2K-040MA0
The MDD025B-N-100-N2K-040MA0 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a compact AC servo motor intended for digital drive controllers where quick speed changes and accurate positioning are required. That operating profile suits packaging, textile, and handling equipment that must start, stop, and reverse without long settling delays. By combining a low-mass rotor with high pole density, the unit converts electrical commands into controlled mechanical rotation for small pick-and-place axes and light gantry drives.
The mechanical interface uses a centering diameter of 40 mm, allowing repeatable alignment against gearboxes or mounting flanges. At standstill, the motor can deliver 0.60 Nm continuously without exceeding its thermal limits, which helps protect the windings during prolonged hold phases. Dynamic moves are supported by a nominal speed of 10000 rpm, so the drive can support high rotational speed before any gearing is considered. The motor uses frame size 025, and the small stator diameter helps keep inertia low for rapid acceleration. Power and feedback leads exit on the A-side, which can simplify routing when several motors are installed close together along a machine frame. This cable direction is useful in compact layouts where clearance around neighboring axes is limited.
An integrated absolute encoder supplies single-turn position data directly to the controller, eliminating external sensors and improving homing behavior after startup. The output shaft is machined with a keyway for secure torque transmission to couplings or pulleys, and the design is supplied without a blocking brake, so any load-holding duty must be handled by the drive or by external mechanics. Electrical commutation relies on resolver feedback, which is valued for noise immunity in electrically busy machine environments. Standard balancing supports smooth rotation at high speed and helps limit vibration at the coupling. Because no shaft seal is fitted, the motor is better suited to clean, dry machine spaces than to areas exposed to coolant or washdown.
