Product Description:

The MDD025A-N-100-N2K-040FC1 is a compact synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It pairs with digital drive controllers to provide rapid acceleration in space-limited axes. By converting drive output into precise rotation, it supports high-speed positioning for machine tools and pick-and-place equipment. The motor has a standard housing and standard balancing, so it mounts into existing frames without extra counterweights.

Its continuous torque capability is 0.33 Nm, meaning the rotor can hold this load indefinitely at standstill without exceeding thermal limits. When commanded by the drive, it can reach a nominal speed of 10000 rpm, which suits the magnetic design and the small 025 frame size. To secure vertical or intermittent loads, a blocking brake is built in, and the brake produces 1.0 Nm of holding torque so the shaft remains fixed when the drive is disabled. Position data are generated by an integrated absolute encoder. The drive uses resolver feedback for closed-loop control. The motor length code A keeps the overall body length minimal, while the lack of a shaft seal reduces friction where sealing is not required.

Power and feedback leads exit on side A, allowing routing toward the cabinet without crossed cables in common gantry layouts. The motor centers in a flange bore with a 40 mm centering diameter so concentricity between the shaft and the driven element is maintained. Electrical power is delivered through a connecting cable with a coupling unit, which provides a fixed connection method and strain relief at the interface. Motion is transmitted through a plain shaft, and the shaft end follows the standard arrangement without a secondary extension on side B. These features support straightforward alignment in high-speed spindles and lightweight auxiliary axes.
