Product Description:

The MDD025C-N-100-N2K-040MR1 is a brushless AC servo unit produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. In automation cells, it pairs with digital drive controllers to translate command currents into high-speed, position-controlled rotation for indexing tables or tooling spindles. By integrating feedback and brake hardware inside a compact frame, the motor allows tightly regulated axis control without adding external holding devices or separate position transducers.

The motor reaches a nominal velocity of 10,000 rpm, so rapid acceleration and short dwell times are possible when lightweight loads must be cycled repeatedly. At standstill, it supplies 0.90 Nm of continuous torque, providing steady holding force for precision stops while the windings remain within thermal limits. An internal blocking brake delivers 1.0 Nm of mechanical torque to secure the shaft after power is removed, preventing drift on vertical or safety-critical axes. Mounting is guided by the 40 mm centering diameter that aligns the housing to the machine interface, and all power and signal lines are plugged through a single industrial connector, simplifying cabinet wiring. The motor uses the C-length version of the 025 frame to keep the envelope size minimal.

All terminals are oriented to the right, which simplifies cable routing when multiple axes are installed in parallel. Position feedback is generated by an integrated absolute encoder, while a separate channel supplies resolver feedback to the drive, giving the controller position data and velocity information. The motor has a keyway shaft without a side-B extension, and no shaft seal is fitted, so it is intended for clean, closed cabinet environments. Rotor balancing is carried out to a standard grade. The aluminum housing follows the series' standard fan-free design, and the compact stator keeps mass and inertia low for responsive servo behavior.
