Product Description:

The MDD025B-N-100-N2K-040PC0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive commands into precise rotary motion for positioning axes and high-speed spindles in automated equipment. Standard housing, shaft-end, and balancing options let the motor fit existing MDD mechanical layouts without additional adapters, so it is often used in compact pick-and-place stations, light assembly tools, and electronics production lines that benefit from high rotational speeds. Its compact format also suits installations where cable space and mounting clearance are limited.

It generates a continuous standstill torque of 0.60 Nm, which is the continuous torque available at zero speed while the motor is energized. During operation, the rotor reaches a nominal speed of 10000 rpm, allowing short cycle times in indexing or spindle tasks. Installation accuracy is aided by a 40 mm centering diameter that aligns the motor on the machine frame. Position feedback is provided by an integrated absolute encoder, so the drive receives position data immediately at startup. Power and sensor conductors exit through a connecting cable with a coupling unit on side A, reducing connector count and simplifying cable routing inside narrow cabinets.

For axes that use external clamps or gravity compensation, the motor is supplied without a blocking brake, which removes residual drag when the shaft is moved by hand. Control loops remain closed because the drive receives continuous angle data during operation. Contaminants are kept out of the bearing chamber by a shaft seal, while torque is transmitted through a keyway that accepts standard couplings. The size 025 frame with length code B keeps inertia low so light loads can accelerate quickly. This arrangement is suitable for clean enclosures that use standard keyed couplings and external holding devices.
