Product Description:

The MDD025B-N-100-N2K-040FA1 is a small-frame synchronous motor built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it provides controlled torque and high rotational speed for positioning and cyclic transport duties in automated equipment. Its compact housing allows direct installation on machine frames where fast response and precise rotary motion are required. In packaging, handling, and other small-axis applications, the motor is suited to repeated start-stop motion and accurate speed control rather than simple constant-speed operation.

Its continuous stall capability is rated at 0.60 Nm, indicating the steady torque the shaft can deliver at standstill without overheating. During motion, the rotor can reach a nominal speed of 10000 rpm, which suits fast indexing cycles on light mechanical loads. The flange face has a centering diameter of 40 mm, allowing the housing to fit accurately into standard mounting recesses while maintaining concentric alignment. This mounting fit helps reduce misalignment between the motor and the driven mechanism. Power and feedback leads exit on side A, and a plug-in connector interface simplifies cable attachment without opening the motor housing. Standard dynamic balancing helps reduce vibration during high-speed operation.

The blocking brake at the non-drive end supplies 1.0 Nm of holding torque so the axis can remain stationary when power is removed. This feature is useful when a mechanism must stay in place during stops or power loss. For position sensing, the drive reads resolver feedback, which tolerates electrical noise and provides rotor angle information to the control loop. Mechanical coupling uses a plain shaft that omits keyways, which suits clamp-style or friction-based couplings. The front end is built without a shaft seal, making the motor better suited for cabinets or enclosed machines where oil spray is not expected.
