MDD025B-N-100-N2G-040ML0
The MDD025B-N-100-N2G-040ML0 is a brushless synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It operates as a torque and speed transducer for digital drive controllers, making it suitable for feed axes, small gantries, and tooling spindles that require quick positioning cycles. By pairing with the manufacturer's intelligent drives, the motor delivers responsive closed-loop motion while maintaining a compact envelope that simplifies mechanical integration in modern automated production lines.
The motor develops a continuous standstill torque of 0.60 Nm, giving the connected axis enough holding force for light clamping or indexing without overheating. A rated mechanical speed of 10,000 rpm allows high-throughput operations such as rapid spindle starts or pick-and-place rotations. Mounting accuracy is aided by a 40 mm centering diameter that aligns the stator housing to the machine frame. Electrical power and feedback conductors terminate through a connector, and these terminations are positioned on the left side of the housing to keep cable routing clear of moving parts and to match the orientation of adjacent modules.
For applications that use external braking devices, the unit is supplied without a blocking brake, eliminating internal drag and reducing mass. Position and speed are monitored through resolver feedback, which provides an analog sine-cosine signal supported by many legacy and current Rexroth controllers. Mechanical torque is transmitted through a keyway shaft, providing positive locking to pulleys or couplings without relying on friction alone. Because the front bearing area is delivered without a shaft seal, the motor is intended for clean environments or cabinets where contamination ingress is already controlled.
