Product Description:

The MDD025A-N-100-N2G-040FL1 is a compact servo motor from Bosch Rexroth Indramat’s MDD Synchronous Motors series. Intended for use with digital drive controllers, it supplies precise torque and high rotational speed to miniature axes found in semiconductor handling, labeling equipment, and light assembly tooling.

At standstill the motor develops a continuous torque of 0.33 Nm, giving stable force for holding or slow-speed positioning without overheating. Its rotor can reach a nominal velocity of 10000 min⁻¹, supporting fast cycle rates when matched with low-inertia loads. Mounting is guided by a centering shoulder diameter of 40 mm, ensuring concentric alignment to gearheads or fixtures. Position and speed are returned to the controller through resolver feedback, which tolerates high shock and ambient noise while still providing absolute shaft angle after power-up.

Additional mechanical features reinforce the performance envelope described above. A blocking brake rated for 1.0 Nm secures the shaft during power loss and allows vertical-axis integration. Power and signal leads exit on the Left side through a keyed circular connector, simplifying cable runs in dense cabinets. The frame corresponds to size 025 with length code A, keeping mass and inertia low for quick acceleration. Motion is transmitted through a plain shaft that omits keyways to minimize backlash; the shaft end is standard on side A only, and there is no shaft seal, so the motor should be installed in clean, dry environments. Standard housing and balancing complete the package.
