Product Description:

The MDD025A-N-100-N2K-040MC0 is a synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is designed for use with digital drive controllers where compact, high-speed rotation positions light loads in automated machinery. Within a motion axis, the unit converts commanded current into the mechanical torque and speed needed for pick-and-place heads, small conveyors, or web-tension stations. Its compact format also suits installations where available mounting space is limited.

Its nominal speed reaches 10000 rpm, enabling short cycle times when paired with a matching inverter. At standstill, the winding provides 0.33 Nm of continuous torque, which is suitable for low-inertia loads. Accurate mounting is aided by a centering diameter of 40 mm, and all power and feedback conductors exit on the A side, which helps simplify cable routing in tight cabinets. Connection is made through a connecting cable with a coupling unit, allowing the motor to be disconnected without disturbing fixed wiring. Standard rotor balancing keeps vibration low at high speed, and the single-ended shaft layout keeps the rear of the motor compact. Because no shaft seal is installed, the motor should be used in clean, dry areas or protected externally.

Position data comes from an integrated absolute encoder working together with resolver feedback, so the controller knows the rotor angle immediately after power-up. This arrangement supports rapid restart after brief stops without a separate reference run. The motor is supplied without a blocking brake, so any static holding force must be provided electrically or by an external clamp. A keyway shaft mates directly to small pulleys or couplings with minimal backlash. The A-length stator core and 025 frame size keep mass and inertia low for axes that accelerate, decelerate, and reverse frequently.
