Product Description:

The MDD025A-N-100-N2K-040PL1 is a compact permanent-magnet servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It serves as the rotary actuator in tightly coordinated digital drive systems, converting commands from an electronic controller into rapid, repeatable motion for pick-and-place axes, small spindles, or indexing stations used across industrial automation. The motor operates from a matched servo inverter that supplies controlled three-phase power. Its compact format suits space-limited assemblies where accurate acceleration and repeatable stopping are required from the same axis.

At its rated operating point, the motor reaches a nominal speed of 10,000 rpm, allowing high-cycle positioning where short travel times are critical. A continuous standstill torque of 0.33 Nm is available without additional cooling, and a blocking brake provides 1.0 Nm of holding torque to secure the load when power is removed. Mechanical alignment is simplified by a 40 mm centering diameter, while power and feedback cabling exit on the left side through a sealed connector. Standard dynamic balancing limits vibration during acceleration, and the cast housing includes an internal shaft seal that helps prevent lubricant migration. A single shaft end without a side-B extension reduces overall length and keeps inertial load low during fast indexing.

Position data are returned to the drive through resolver feedback, and an integrated absolute encoder allows power-on commutation without a homing routine. The shaft uses a DIN 6885 keyway to transmit torque without slip. Frame designation 025 and length code A indicate the smallest build in the series, which helps keep rotor inertia low for quick response. The connector orientation helps the motor fit into compact machine spaces.
