Product Description:

The MDD025B-N-100-N2G-040PE0 is a compact servo motor manufactured by Bosch Rexroth Indramat for integration with digital drive controllers in the MDD Synchronous Motors series. Supplied in a standard housing with standard dynamic balancing, the unit uses frame size 025 and motor length code B. Its primary role in industrial automation is to provide precise rotary motion where high speed and low continuous torque are suitable, such as small indexing axes or light pick-and-place stations. Its compact format also suits installations where moving mass and available mounting space must both remain limited.

The motor’s nominal speed reaches 10000 rpm, allowing rapid positioning cycles when paired with high-bandwidth drives. A continuous standstill torque of 0.60 Nm indicates the sustained load the magnetic circuit can hold without overheating while the rotor is locked. Accurate mechanical alignment is supported by a centering diameter of 40 mm, which matches common machine flanges. Power and feedback conductors exit on the left side, simplifying cable routing when the machine layout requires service access from one direction. Rotor position is returned through resolver feedback; this analog transducer supplies angle data over each electrical cycle and maintains operation at high shaft speeds without incremental count loss.

An integral shaft end with a keyway transmits torque to pulleys or couplings, and a durable shaft seal helps limit lubricant migration into the stator air gap. The motor is delivered without a blocking brake, so applications that need static holding must rely on external clamping or drive torque. Electrical terminations are provided by a connecting cable with coupling unit, which eliminates separate terminal boxes and reduces assembly time. This arrangement reduces extra connection hardware around the motor body and helps keep installation areas less crowded. The standard housing, the absence of a side B shaft, and the resolver electronics keep the overall envelope compact for light automation machinery.
