Product Description:

Bosch Rexroth Indramat produces the MDD025A-N-100-N2K-040FR0 synchronous servo motor as part of the MDD Synchronous Motors series. Designed for pairing with digital drive controllers, the unit converts electrical commands into controlled mechanical rotation for tasks that demand high speed and repeatable positioning in automated machinery. This compact frame size 025 model serves conveyor pick-and-place heads, electronics assembly spindles, and other axes where minimal mass and rapid acceleration are priorities.

The motor delivers a continuous stall torque of 0.33 Nm, allowing steady force output when the shaft is locked while the drive maintains current. Its rotor can reach a nominal speed of 10000 rpm, and this high speed suits fast-cycling platforms that prefer transmission reduction over larger gear ratios. Accurate mechanical alignment is supported by a centering diameter of 40 mm, so the flange seats concentrically on standard machine frames. Power and feedback lines exit on the right side, and the interface uses a single industrial connector. Standard rotor balancing keeps vibration low, the housing follows the normal series outline, and motor length code A corresponds to the shortest stator stack to minimize inertia.

High-resolution commutation is handled by the motor’s Resolver feedback, while the built-in integrated absolute encoder provides position information after each power cycle. Stopping torque is not available internally because the unit ships without a blocking brake, so any holding force must come from the drive or external mechanics. The output end is a plain shaft without a keyway, and the front bearing has no shaft seal to reduce friction. The omission of a side-B shaft extension further shortens the assembly, helping it fit into cramped pick-and-place heads and small gantries.
