MDD025B-N-100-N2G-040GE0
The MDD025B-N-100-N2G-040GE0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is installed in compact axes where precise velocity and torque regulation are required for pick-and-place units, small machining spindles, or auxiliary packaging stations. A standard housing protects the stator assembly, and power and feedback are routed through a connecting cable with a coupling unit so the motor can be integrated directly into the drive chain of modular automation cells.
The rotor can hold a continuous load of 0.60 Nm at standstill, allowing tight position control during static clamping or indexing operations. Under rated excitation, it reaches a nominal speed of 10000 rpm, giving short cycle times in high-throughput equipment. Position and velocity data are returned through resolver feedback, which provides analog absolute sensing that tolerates electrical noise. Service wiring is simplified because the power and encoder connectors are mounted on the left side of the frame. Mechanical coupling is handled by a plain shaft, and the absence of keyways helps minimize concentricity errors while suiting clamp-style couplings. Standard housing geometry, motor size 025, and the B-length code keep the envelope small for side-by-side mounting.
Dynamic performance is supported by standard balancing, which limits residual vibration when the rotor tracks rapid speed changes. The flange face includes a centering pilot of 40 mm, helping maintain coaxial alignment with gearheads or belt pulleys. Contaminant ingress along the output journal is restricted by an integrated shaft seal, enabling installation in lubricated machine zones. The unit is supplied without a blocking brake, so any required holding function must be provided by the controller or by an external brake on the load side. The motor also has a single-ended shaft with no side B extension and uses a standard housing.
