Product Description:

The MDD025C-N-100-N2K-040PF1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive output into rotary motion for precision positioning, velocity control, and cyclic tasks. It is suited for automated assembly equipment, pick-and-place stations, and compact machine tools where accurate shaft response is required. Its synchronous design supports controlled motion in applications that depend on repeatable speed and position behavior.

This model delivers a continuous standstill torque of 0.90 Nm, allowing the axis to hold loads without overheating when the shaft is locked. Under rated excitation, it reaches a nominal speed of 10,000 rpm, which supports short cycle times in high-speed applications. An integrated blocking brake supplies 1.0 Nm of static holding torque during power-off states. The motor mounts with a centering diameter of 40 mm, and power and feedback are routed through a connecting cable with a coupling unit for a detachable connection without soldered joints. The rotor is balanced to a standard quality grade to reduce vibration at high speed, and an integrated absolute encoder provides multi-turn position data for closed-loop operation. The housing uses standard construction, and a shaft seal helps protect the interior from splash ingress.

Cabling exits on the right side of the stator so conductors can follow a common raceway. The drive can read rotor angle through resolver feedback, which supports sinusoidal commutation. Mechanical length code C indicates the longest stack in the 025 frame, increasing active length while keeping the same basic frame size. The output shaft has a keyway for positive torque transmission, and the motor uses a single shaft end on side A rather than a second shaft extension. This arrangement keeps the rear end of the motor closed and supports compact installation in confined machine spaces.
