Product Description:

The MDD025B-N-100-N2K-040GL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise rotary motion for positioning or speed-control tasks in automated machinery such as small pick-and-place axes or spindle drives. The motor uses size code 025 with length code B, giving it a compact frame for tight mechanical envelopes. When paired with a compatible controller, it can support repeatable starts, stops, and speed changes during automated cycles.

This model delivers a continuous standstill torque of 0.60 Nm, which supports light loads while the rotor is energized and stationary. During motion, it reaches a nominal speed of 10,000 rpm, allowing high-speed cycles where short process times are required. This operating range is useful in compact machinery where fast response and short move times are important. A centering diameter of 40 mm provides the pilot fit that aligns the motor housing on the machine plate and helps keep coupled mechanics concentric. Power and feedback cabling exits on the left side of the stator, which can simplify wiring when drives are mounted in sequence. Electrical terminations are made through a molded connector, and the rotor-stator assembly uses a standard dynamic balancing grade to reduce vibration transmitted to nearby components.

An integrated absolute encoder provides single-turn position data at power-up, while complementary resolver feedback supplies analog angle information for current control. This combination lets the drive monitor rotor position immediately after startup and maintain stable control during changing operating conditions. The shaft is supplied with a shaft seal, so the internal bearings are protected against coolant mist or fine dust. The plain shaft is a single-ended design without a side B extension. The unit is built without a blocking brake, so external holding is required if the application must remain fixed when de-energized.
