MDD025A-N-100-N2K-040MC1
The MDD025A-N-100-N2K-040MC1 is a compact AC servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended to pair with digital drive controllers, supplying closed-loop rotary motion in automated pick-and-place modules, miniature actuators, and precision tooling stages where high speed and tight position control are required. Its compact format suits installations where limited mounting space and fast response are both important.
At standstill, the motor can deliver a continuous torque of 0.33 Nm, which is the load it can hold continuously without overheating. During operation, it can reach a nominal speed of 10000 rpm, supporting fast cycle times in light-inertia axes. A centering diameter of 40 mm allows accurate concentric mounting to gearheads or flanges, which helps reduce radial misalignment. The integrated blocking brake supplies 1.0 Nm of holding torque, allowing vertical axes to remain stationary when power is removed. For power and feedback, the motor is supplied with a connecting cable with coupling unit, which simplifies installation and keeps electrical connection routing straightforward.
The housing is balanced to a standard grade, and all electrical terminations exit on Side A, so cable routing stays consistent in multi-axis frames. A single shaft end machined with a keyway transfers torque to pulleys or couplings, while the design is intentionally without a shaft seal to avoid added friction in clean, enclosure-mounted environments. An integrated absolute encoder works alongside resolver feedback to report real-time rotor position, supporting precise velocity regulation and quick homing sequences. This layout is useful in compact automation systems where stable feedback and predictable cable direction are important for repeatable motion.
