Product Description:

The MDD025B-N-100-N2K-040GR1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it delivers controlled torque and speed for compact axes that need fast response and accurate motion. In automated assembly systems, electronics equipment, and light material handling units, this motor supports precise angular positioning and repeatable velocity control. Its compact format makes it suitable for installations where available space is limited and moving masses must remain low.

At its nominal speed of 10,000 rpm, the rotor can sustain continuous operation without losing synchronization, which makes the unit suitable for compact spindle tasks. During standstill, it delivers 0.60 Nm of continuous torque, and the installed blocking brake adds 1.0 Nm of static holding torque for power-off retention. Mechanical alignment uses a 40 mm centering diameter, and all power and feedback plugs exit on the right side to simplify cable routing in narrow machine spaces. A plain shaft couples to friction hubs or collets, while the molded connector, standard housing, and compact body help the motor fit narrow Z-axes and other tightly spaced assemblies.

Position data is generated by an integrated absolute encoder, which allows immediate commutation after power-up without a homing routine. For dynamic control loops, the drive also receives resolver feedback, providing continuous sine-cosine signals that remain stable in electrically noisy environments and at high rotational speed. A fitted shaft seal helps keep coolant or dust out of the front bearing cavity while retaining lubricant during rapid reversals. The motor has a shaft end on side A only, while side B remains closed to keep the overall package short.
