Product Description:

The MDD025B-N-100-N2G-040MA0 is an AC synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for closed-loop motion axes driven by digital amplifiers in packaging machines, pick-and-place modules, and other light automation equipment where small servomotors must respond quickly and repeatably. By combining permanent-magnet excitation with electronic commutation, the motor supplies high-speed positioning capability required for tightly regulated industrial tasks. This makes the motor suitable for compact indexing units and transfer axes that need accurate motion over short, repeated cycles.

At standstill, the motor can deliver a continuous torque of 0.60 Nm, allowing fine force control on light mechanical loads. The rotor is designed for operation up to 10,000 rpm, so high-speed duty cycles can be achieved without mechanical gear reduction. Electrical and feedback wiring leave the housing on the A-side, which simplifies cable management when the unit is mounted in compact cabinets. A centering collar with a diameter of 40 mm locates the flange accurately against the machine frame and helps keep radial runout low. Position data are returned through resolver feedback, which provides stable angle signals with strong noise immunity in electrically harsh environments.

For mechanical integration, the output shaft is machined with a keyway, enabling direct coupling to pulleys, miniature gear sets, or universal joints without custom hubs. The motor is supplied without a blocking brake, so vertical or safety-critical axes must rely on the drive’s torque holding or an external clamp when power is removed. Power and resolver circuits terminate on a compact connector, eliminating permanent leads and supporting quick replacement during service. The unit is a motor for digital drive controllers, and its B length code with the 025 frame gives a compact format with low inertia and low mass. Standard rotor balancing is used for smooth rotation at high speed. The motor also omits a shaft seal, which suits installations that are already protected inside the cabinet.
