Product Description:

The MDD025C-N-100-N2G-040FF0 is a compact synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical power into precise rotary motion required in packaging, pick-and-place, and small assembly stations. The unit’s mechanical outline follows the manufacturer’s 025 frame to fit tight machinery envelopes while delivering high dynamic response to position commands from a compatible drive.

Key operating data define how the motor interfaces with a drive. At a standstill it can supply 0.90 Nm of continuous torque, which is the sustainable twisting force for holding or low-speed tasks without overheating. When excited at rated frequency the rotor reaches a nominal speed of 10000 min⁻¹, allowing rapid cycle times in servo axes with low inertia loads. Rotor position is returned to the controller through integrated resolver feedback, enabling sinusoidal commutation and closed-loop accuracy even during acceleration. Accurate centering is supported by a 40 mm pilot diameter that aligns the flange to the machine interface and minimizes run-out. Power and signal conductors leave the housing through a connecting cable with coupling unit, simplifying installation because the mating half is already terminated.

The remaining construction details refine how the motor is mounted and sealed. Cable glands are positioned on the right side, so panel designers can route harnesses away from moving parts. The shaft is a plain shaft and follows the manufacturer’s standard end-machining, with no side-B extension to keep the overall length low. Because the design is supplied without a blocking brake, external holding devices or drive torque must secure vertical axes when power is removed. The frame size code 025, length code C, a standard housing, factory balancing, and the absence of a shaft seal tailor the motor to clean, dry environments where minimal axial space is available.
