Product Description:

The MDD025C-N-100-N2G-040MB1 is a brushless AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is intended to deliver precise rotational positioning and speed control on compact machine axes in industrial automation. Its compact format makes it suitable for small handling systems, light indexing tasks, and other applications where fast response is important but installation space is limited. It can be paired with digital servo electronics in packaging equipment, laboratory devices, and other machinery that requires accurate repeatable motion.

This unit reaches a nominal speed of 10,000 rpm, so the rotor can follow rapid command changes on high-speed axes. The motor provides a continuous standstill torque of 0.90 Nm, which indicates the torque available while the shaft is held at zero speed by the drive. An integrated blocking brake adds up to 1.0 Nm of braking torque for power-off holding or emergency stopping. The centering diameter is 40 mm, which helps align the motor on a matching flange. Power and feedback leads exit on Side B, and the wiring uses a sealed connector for a compact rear connection. The housing is made of standard cast aluminum, and the motor uses a single shaft end rather than a second output on the rear.

The motor uses resolver feedback to report rotor position to the drive for closed-loop control. This arrangement supports precise speed regulation during frequent starts and stops. Torque is transmitted through a keyway shaft, which allows secure coupling to gears, pulleys, or other driven elements. The front bearing seat is supplied without a shaft seal, so the installation should protect that area from dust, coolant, or other contaminants. Size code 025 and length code C identify the motor’s compact stator geometry, which suits short-cycle motion on small machine axes.
