MDD025B-N-100-N2K-040FR0
The MDD025B-N-100-N2K-040FR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for digital drive controllers, it supplies tightly regulated torque and speed for compact pick-and-place axes, light rotary tables, and small spindle drives used throughout automated production lines. A standard aluminum housing protects the stator, and the rotor is balanced to a standard grade so vibration stays within allowable limits even at high rotational speed.
The motor reaches a nominal speed of 10000 rpm, giving it a wide mechanical speed range without external gearing. At standstill, it can provide a continuous torque of 0.60 Nm, which is suitable for modest holding loads while current remains within continuous drive limits. The flange has a centering diameter of 40 mm for coaxial alignment with gearboxes or mounting plates. The motor has size code 025 and length code B, which indicate a compact housing and short installation depth. The shaft end is supplied in a standard single-ended form without a side-B extension, and the feedback system provides position data to the drive for commutation and velocity control.
All electrical terminations exit on the right. Each interface uses a detachable connector, which suits modular machine layouts and keeps wiring straightforward. Angular position is also available through an integrated absolute encoder, allowing the drive controller to recover rotor location after power cycling without a homing move. Because the motor is supplied without a blocking brake, external holding methods are required when static holding is needed, and the lack of a shaft seal limits use to protected enclosures where liquids and dust are controlled. Power is transmitted through a plain shaft that accepts clamp couplings or adhesive-bonded pulleys.
