MDD025C-N-100-N2G-040MF0
The MDD025C-N-100-N2G-040MF0 servo motor is built by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is supplied in the compact 025 frame for use with digital drive controllers where rapid speed changes and precise positioning are required. In automated assembly stations, indexing units, or pick-and-place axes, the motor converts electrical power from the drive into controlled mechanical rotation. Its synchronous design supports stable torque production, quick response to command changes, and repeatable positioning during short motion cycles.
A continuous standstill torque of 0.90 Nm indicates the load it can support indefinitely while the windings remain within thermal limits. The maximum operating speed is 10,000 rpm, a value suited to applications that benefit from fast acceleration and short cycle times. Cable exits are oriented to the right side, so the machine layout must provide clearance for routing and service access. The mounting flange has a centering pilot of 40 mm, which helps align the motor concentrically and reduce coupling misalignment during acceleration. For feedback, resolver feedback supplies rotor position data to the controller, allowing the drive to regulate speed and position through a closed loop.
The drive end uses a shaft with a keyway, which allows positive torque transfer to pulleys, pinions, or small gear sets without relying only on friction clamping. Power and signal conductors connect through a connecting cable with a coupling unit, reducing separate connection steps and helping protect the housing against dust. Because the motor is supplied without a blocking brake, holding torque must be provided by the drive or by external mechanics when the axis is stationary. The motor uses length code C, which is the longest version in the 025 frame and adds axial stack length without changing the centering diameter.
