Product Description:

The MDD025B-N-100-N2G-040FR0 is a compact AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for digital drive controllers and provides precise torque and speed control for light-duty axes in packaging, small handling, and electronic assembly lines. Its compact housing suits tightly spaced machinery, and the motor responds quickly to drive commands during positioning and speed-controlled motion. This makes it well suited to small axes that start, stop, and reverse frequently during automated cycles.

Accurate mechanical coupling is set by a centering diameter of 40 mm, letting the motor seat concentrically in flanged housings. Power and feedback leads are routed on the right side through a single industrial connector. When held at zero speed, the shaft can deliver a continuous torque of 0.60 Nm, which suits low-inertia loads such as pick-and-place heads. The unit is supplied without a blocking brake, so holding force during power-off must come from the drive or external mechanics. Rotor position is communicated by resolver feedback, which provides analog angle data with high noise immunity for the controller. Standard dynamic balancing and a standard housing finish support stable operation in compact machine assemblies.

High-cycle applications benefit from the nominal speed capability of 10,000 rpm, which lets the axis reach commanded velocities quickly without oversized gearing. Torque is transmitted through a plain shaft that omits keys to minimize play, and no secondary shaft is provided on side B. The plain shaft also works well with clamping couplings that need accurate concentricity and low backlash at the motor interface. Because the front end is supplied without a shaft seal, the motor is best installed inside protected cabinets or gearboxes where dust and fluid exposure are controlled. The frame follows size code 025 with length variant B, which keeps mass and rotational inertia low. The connector interface allows quick cable connection and helps keep installation compact.
