Product Description:

The MDD025A-N-100-N2K-040FB1 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded currents into precise rotary motion for lightweight automation axes. The A-length, size-025 frame keeps inertia low, while permanent-magnet excitation lets the rotor accelerate quickly. Used with a matching drive, the unit positions small tools, grippers, and indexing tables in pick-and-place modules, laboratory equipment, and compact packaging machinery.

At standstill, the windings generate a continuous torque of 0.33 Nm, allowing the axis to hold or creep without thermal overload. When full velocity is demanded, the rotor can reach a nominal speed of 10,000 rpm, supporting fast cycle times in short-stroke applications. A blocking brake rated at 1.0 Nm secures vertical loads during shutdown or emergency stop events. Accurate concentric mounting is aided by a 40 mm centering diameter on the end flange, and the rotor is supplied with standard balancing so vibration remains within acceptable limits for nearby precision bearings.

Electrical interfaces are routed to the rear because the power and feedback plugs are located on side B of the housing and use a keyed connector for quick exchange. Position data come from an integrated absolute encoder together with resolver feedback, giving the controller both coarse and high-resolution signals. A smooth plain shaft is provided as the output element; the rear face carries no second shaft end, and the motor is delivered without a shaft seal, so external sealing must be added if contaminants are present. The standard housing, compliant balancing, and compact form let the unit couple directly to miniature pulleys or friction wheels without additional machining.
