Product Description:

The MDD025B-N-100-N2K-040MD0 is a small-frame synchronous servo motor manufactured by Bosch Rexroth Indramat for use in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precisely regulated rotary motion that can be coordinated with CNC or PLC axes in printing stations, pick-and-place heads, or compact packaging tools. Its construction follows the series' standard housing outline, which helps it fit machine layouts intended for this motor class.

During continuous stall operation, the motor delivers 0.60 Nm of torque, indicating the sustained load it can hold without overheating when the rotor is locked. The rated mechanical speed reaches 10000 rpm, a value that supports high-throughput indexing while allowing direct coupling to miniature gear stages. Position data is generated by an integrated absolute encoder, and motion loops close through resolver feedback, providing single-turn position resolution and good immunity to electrical noise. Electrical and feedback connections exit on side B, so cables can be routed away from moving machinery. A centering diameter of 40 mm aligns the flange in precision fixtures and supports repeatable concentricity during installation.

A connecting cable with a coupling unit locks to the housing and provides a secure interface for power and feedback wiring. The shaft uses a keyway shaft profile, allowing positive torque transfer into pulleys or pinions, and the front end is delivered without a shaft seal, so the bearing area requires protection from coolant or dust ingress. The motor is supplied without a blocking brake, so holding duty during power loss must be handled by the drive or an external mechanical latch. Standard balancing and the B-length housing provide the mass distribution typical of this frame size.
