Product Description:

The MDD025B-N-100-N2K-040FL0 synchronous servo motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts regulated inverter power into rotary motion for compact pick-and-place, indexing, or auxiliary spindle duties within automated production lines. The frame size 025 and length code B indicate a slim stator that fits restricted spaces and supports compact axis layouts. Its compact format also suits machinery that requires rapid starts, short travel distances, and frequent direction changes. It is suitable for compact automation equipment where installation space is limited.

Its continuous stall capability is 0.60 Nm, permitting stable low-speed holding without overheating. When commanded by the drive, the rotor can accelerate up to 10000 rpm, a speed suited to miniature conveyors and high-cycle tooling. Mechanical centering is handled by a 40 mm pilot diameter that aligns the flange and helps keep runout low. Service wiring is simplified because the power and feedback terminals sit on the left side, and all leads terminate on a sealed connector rather than fixed glands. Because the connections are grouped on one side, the motor can be mounted close to guards, brackets, or adjacent axes without awkward cable bends.

Primary commutation data are delivered through resolver feedback, while an integrated absolute encoder reports rotor angle to the controller without homing cycles. The motor is supplied without a blocking brake, so holding force for vertical axes must come from drive torque or an external clamp when power is removed. A plain shaft with no secondary end transmits torque through friction or collet couplings and avoids keyway stress points. This shaft arrangement is well suited to light rotating loads that benefit from low backlash at the coupling. The combined feedback arrangement supports accurate commutation and stable positioning during rapid starts, stops, and reversals.
