Product Description:

The MDD025A-N-100-N2K-040MR1 is a compact synchronous motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed for use with digital drive controllers, it provides controlled torque and speed for small positioning axes in assembly equipment and electronics handling lines. The frame follows the standard housing format and uses standard dynamic balancing to keep vibration within servo-grade limits during rapid motion. A size code 025 stator and the short length code A minimize weight and rotor inertia, allowing the motor to fit where mounting space is limited without sacrificing responsive acceleration.

The stator-rotor design supports a nominal speed of 10,000 rpm, so the shaft can follow high-frequency motion profiles generated by the drive. This speed capability suits compact feeders, test fixtures, and other light mechanisms that depend on fast reversals and short cycle times. At standstill, the motor can deliver 0.33 Nm continuously within the standard housing. Mechanical centering is handled by a 40 mm pilot diameter that aligns the flange with gearheads or machine plates. The pilot helps seat the motor accurately against the mating surface before the mounting bolts are tightened. Power and feedback lines exit on the right side because the connector block is fixed there, and a single-plug connector simplifies cabling in densely populated cabinets. The shaft is supplied as a standard end without a side-B extension, ready for coupling or pulley installation.

A blocking brake is integrated to secure vertical or indexing loads, and its release torque is rated at 1.0 Nm. Position data is furnished by an integrated absolute encoder that stores multi-turn information, while the drive uses resolver feedback for closed-loop commutation. The output shaft uses a keyway profile so torque is transferred without slip, and the front face is delivered without a shaft seal for dry cabinet interiors rather than washdown areas.
