MDD025C-N-100-N2G-040FR0
The MDD025C-N-100-N2G-040FR0 is a small-frame synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled current from an inverter into rotary motion for compact pick-and-place units, light indexing tables, and other high-speed automation axes where precise velocity control is required. Its compact format suits installations where available mounting space is limited but responsive motion is still necessary. The motor is intended for closed-loop operation with a matching drive that regulates current, speed, and position during repetitive machine cycles in compact machinery.
This model is rated for a nominal speed of 10000 rpm, allowing fast rotation in compact automation axes. At standstill it delivers 0.90 Nm of continuous torque, which supports light loads when the axis remains energized. Positioning repeatability is supported by standard dynamic balancing, which helps reduce residual vibration around the centering pilot. The pilot measures 40 mm and keeps the mounting flange concentric with the machine interface. Power and feedback conductors exit on the right side through a keyed connector, which helps cable routing in tight enclosures.
Feedback is generated by an integrated resolver feedback element, providing rotor angle signals to the drive controller for closed-loop control. The motor is supplied without a blocking brake, so any holding function during power loss must come from the machine or the drive system. Mechanical output is transferred through a plain shaft, which is suited to clamping-style couplings in clean installations. The front bearing area is built without a shaft seal, so the motor is best used in dry environments with limited contamination. A standard aluminum housing with natural-convection fins keeps the assembly light and helps remove heat during continuous operation while accommodating the C-length winding package for the 025 frame size.
