MDD025A-N-100-N2G-040GB1
The MDD025A-N-100-N2G-040GB1 is a miniature synchronous servo motor manufactured by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It interfaces with digital drive controllers to convert programmed current profiles into precise rotary motion for pick-and-place stations, dosing pumps, and other tightly regulated axes within automated lines. Permanent-magnet excitation and closed-loop control let the motor execute rapid start-stop cycles that support high throughput in industrial automation. Its compact format also suits machinery where low moving mass and repeatable motion are important in short indexing sequences. This makes it a practical choice for small mechanisms that must reverse quickly without sacrificing positioning consistency over long production runs.
The motor’s electromagnetic ratings indicate how it performs under load. At a continuous standstill torque of 0.33 Nm, it can hold small indexing tables or tensioning spindles without overheating. Once released, the rotor can accelerate to a nominal speed of 10,000 rpm, making the unit suitable for high-cycle positioning tasks. A blocking brake rated for 1.0 Nm keeps the shaft locked when power is removed. Correct axial alignment is simplified by the 40 mm centering diameter, while internal resolver feedback supplies rotor position data to the controller. The short A-length housing, standard dynamic balancing, and plug-in connector interface help keep installation compact and stable during repeated motion.
Additional mechanical features complete the package. Operation is supported by a shaft seal, which limits lubricant escape and helps keep fine particulates away from internal components. Power and sensor leads exit on side B, allowing tight cabinet layouts when the opposite face is needed for mounting. The rotor uses a plain shaft, and the design omits a secondary shaft end to reduce coupling complexity. Within the compact 025 frame size, the standard housing supports air convection cooling and fits light automation stages that require accurate holding and responsive velocity control during frequent cycling.
