Product Description:

The MDD025A-N-100-N2G-040MB1 is a compact synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated electrical output from a drive into rotary motion that can be coordinated with CNC or PLC commands in automated assembly, packaging, or pick-and-place axes. This type of motor is commonly used where the controller must command quick starts, stops, and short indexing moves with repeatable motion. Because it works with a digital drive, current and speed can be regulated closely during dynamic duty cycles.

The motor reaches a nominal speed of 10000 rpm, enabling high-cycle positioning in light mechanical stages. At standstill, it can deliver 0.33 Nm of continuous torque, while a normally energized blocking brake provides 1.0 Nm to hold the load when power is removed. A centering diameter of 40 mm aligns the housing in precision mounts, and power and feedback conductors exit on side B so cable routing can be kept away from moving parts. That layout supports consistent mechanical alignment and keeps the cable exit on one end of the motor body. Standard balancing helps limit shaft vibration across the full speed range, and the housing uses the default series style for general indoor machinery.

The motor uses resolver feedback for real-time position loops without requiring a high-resolution encoder. Resolver signals remain useful in applications that value simple, durable feedback rather than very fine encoder resolution. The output shaft uses a keyway for torque transfer to couplings, and the motor is built without a shaft seal, so it is intended for clean areas free of liquid spray. Frame size 025 and length code A keep the package short for tight installation spaces. The short body can fit crowded machine sections where adjacent tooling or guards leave limited axial space. Connector-based wiring keeps the electrical interface compact, and there is no rear shaft end, which helps reduce mass at the back of the motor.
