Product Description:

The MDD025A-N-100-N2G-040FE0 is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Built for digital drive controllers, the unit supplies precise rotary motion to pick-and-place heads, light conveyors, and small spindle axes in automated equipment where quick response and repeatable positioning are required. A standard housing protects the stator, and the motor uses a plain shaft without a shaft seal, so it can couple directly to light mechanical loads in machines that provide their own external sealing.

At its rated excitation, the rotor reaches 10000 rpm, enabling fast positioning cycles on compact axes. The servomotor sustains 0.33 Nm of continuous standstill torque, so it can hold moderate static loads without overheating. Machine alignment is simplified by a 40 mm centering diameter that seats the motor concentrically in a pilot bore. All power and feedback conductors exit on the left side, which can ease cable routing in gantry layouts or tight machine frames. Motion feedback relies on resolver feedback, giving the drive a robust rotor-position signal for closed-loop control across the speed range. The shaft is provided only on side A, and the motor comes without a blocking brake, so applications that require mechanical holding need an external brake or clamp.

The removable interface is a connecting cable with coupling unit, which allows the motor to be disconnected without hardwiring at the housing. The motor uses frame size 025 with the short A length code, keeping the package compact and helping reduce rotor inertia for quick acceleration. A Standard balancing quality limits residual vibration across the speed range and supports smooth running in small-axis motion systems. Low rotor inertia supports short indexing moves in compact automation axes.
