MDD025A-N-100-N2G-040GC1
The MDD025A-N-100-N2G-040GC1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated current from an inverter into mechanical rotation that positions or drives light axes in packaging machines, pick-and-place gantries, and similar equipment where fast speed changes are required. This operating profile suits compact axes that need quick acceleration, controlled stopping, and consistent response during repetitive cycles. Standard balancing limits vibration at high speed.
This model develops a continuous standstill torque of 0.33 Nm, giving it enough static force to hold small loads without overheating. During normal operation it can reach a nominal speed of 10,000 rpm, allowing short index times in high-cycle processes. Position and velocity data are returned to the drive through resolver feedback, which is resistant to electrical noise during operation. A blocking brake rated at 1.0 Nm locks the rotor when the system is disabled, preventing drift on vertical or rotary indexing stations. The mechanical output is provided by a plain shaft, so no second shaft projects from side B. This shaft style supports direct coupling where a keyed connection is not required.
Cabling exits on side A and uses a connecting cable with a coupling unit, simplifying motor connection where compact routing is needed. The flange has a centering diameter of 40 mm for accurate concentric alignment to the machine frame, and there is a shaft seal that keeps lubricants inside and contaminants out. The enclosure uses the standard housing pattern for size 025 motors with length code A, keeping weight and thermal mass low. The centering fit helps keep the motor face aligned with the driven assembly during installation and operation.
