MDD025A-N-100-N2G-040PC0
The MDD025A-N-100-N2G-040PC0 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a compact synchronous servo motor intended for direct connection to digital drive controllers in automated assembly, packaging, and handling modules. By supplying precise torque at high rotational speed, the unit converts electrical commands from the controller into tightly regulated mechanical motion that can be scaled to small positioning axes or auxiliary spindles on larger machines.
This motor uses standard dynamic balancing to limit vibration and has a centering diameter of 40 mm for repeatable alignment to gearbox flanges or mounting brackets. Power and feedback conductors exit on Side A, and the factory-installed connecting cable with coupling unit shortens installation because intermediate terminal blocks are unnecessary. During continuous duty at standstill, the rotor develops 0.33 Nm of holding torque, allowing light loads to remain fixed when the controller maintains excitation. Once in motion, the magnetic design supports synchronous rotation up to 10000 rpm, a speed suitable for fast pick-and-place heads or high-frequency metering pumps. Housing and shaft-end configurations follow the standard pattern of the series, and the frame is identified by motor size 025 with a length code of A, indicating the shortest stator stack in this family.
The position loop receives signals from resolver feedback, so the drive can monitor rotor position during operation. Torque is transmitted through a shaft machined with a keyway, simplifying coupling to pulleys or pinions. Contamination is limited by a shaft passage with a shaft seal, which helps retain lubricants and reduce the entry of debris into adjacent mechanisms. The motor is supplied without blocking brake, so when power is removed the application must secure the load through external braking or by holding torque from the drive. A standard housing completes the assembly and matches enclosure dimensions across the MDD portfolio.
