Product Description:

The MDD025B-N-100-N2K-040MB0 is a compact AC synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is used with digital drive controllers on lightweight machine axes where high-speed positioning and repeatable torque are required. The motor converts controller commands into controlled rotary motion for pick-and-place equipment, indexing tables, and similar automation tasks. Its compact format makes it suitable for installations where axis mass and available space must both be kept low.

The frame uses a centering diameter of 40 mm, which provides a fixed reference surface for coaxial mounting to gearheads or flanges. All power and feedback leads exit on side B, and the single plug-in connector keeps cable routing concentrated on one side of the motor. When energized, the rotor can generate 0.60 Nm of continuous holding torque at standstill, which helps the axis remain stable during short dwell periods. During motion, the motor reaches a nominal speed of 10000 rpm, making it suitable for fast cycling applications. Standard dynamic balancing and the normal MDD housing profile allow operation without external fans, and the motor fits machine layouts that need a compact drive package.

Position feedback is handled by an integrated absolute encoder, while the drive also receives coarse commutation data through the built-in resolver feedback channel. This combination gives the controller both precise position information and commutation signals without requiring external transducers. The output shaft uses a keyway for torque transmission through compatible couplings or hubs. The motor is supplied without a shaft seal, so it is intended for clean, dry environments where liquid ingress is not expected. It also comes without a blocking brake and without a second shaft end, which helps keep overall length and rotating inertia low.
