MDD025A-N-100-N2G-040PF1
The MDD025A-N-100-N2G-040PF1 is a compact AC synchronous motor engineered by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts drive current into controlled mechanical rotation for indexing tables, small pick-and-place heads, and other fast-cycle automation axes. Its compact format suits small servo axes that need quick response without adding much mass to the moving assembly. The size 025 motor with short length A fits installations where axial space is limited, and the integrated blocking brake helps secure the load during power-off events.
At standstill, the rotor can deliver 0.33 Nm of continuous torque, providing stable holding force for precision positioning without overheating. During rapid acceleration or vertical holding, the blocking brake supplies 1.0 Nm of static torque so the load remains fixed when the drive is disabled. High-speed moves are supported by a nominal speed of 10,000 rpm, enabling short indexing times in light servo duties. Mechanical coupling is simplified by a centering diameter of 40 mm, which helps align the motor face to gearboxes or machine frames with minimal runout. Closed-loop control uses resolver feedback, which reports rotor position and speed to the drive for stable performance under dynamic load changes. This combination is suitable for small axes that require quick starts, short travel intervals, and accurate positioning.
The rotor and shaft use standard balancing, which helps keep vibration levels low across the speed range. A standard housing encloses the stator windings, and a shaft seal is fitted to help limit oil ingress at the output journal. Power and feedback conductors exit on the right through a connecting cable with a coupling unit, which reduces plug length inside narrow cabinets and helps with cable routing in tight spaces. Torque is transmitted through a single-ended keyway shaft on the A-side output. Only the A-side shaft end is provided, which helps keep the overall package short for compact machine layouts.
