Product Description:

Bosch Rexroth Indramat manufactures the MDD025A-N-100-N2K-040PF0, a compact synchronous servo motor in the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into precise rotational motion for small industrial axes. The size 025 housing fits tight assemblies, and the standard rotor balancing helps keep operation smooth during rapid starts, stops, and short positioning moves. This motor is well suited for pick-and-place stations, labeling heads, and other automation tasks that require low inertia and fast response.

The rotor can deliver a continuous standstill torque of 0.33 Nm, which supports stable holding force during closed-loop positioning. When the axis is running, the motor reaches a nominal speed of 10000 rpm, allowing very fast index cycles on compact equipment. Accurate centering on mating machine surfaces is provided by a 40 mm pilot diameter, which helps the motor seat correctly on compatible mounts. Angular position is returned through resolver feedback, which gives the controller a durable feedback signal in electrically noisy environments. The motor is supplied without a blocking brake, so any holding function must be provided by the drive or by external mechanics.

Cabling exits to the right side and is routed by a connecting cable with coupling unit, which supports a compact electrical connection. Power is transferred through a hardened output journal that uses a keyway shaft for positive torque transmission, and the rotor is built without a side B shaft end. Running surfaces are manufactured with shaft seal, which helps limit the entry of lubricant and outside contamination near the bearing area. The motor also uses an A-length frame and a standard housing finish, keeping the package compact for dense multi-axis machine layouts.
