MDD025C-N-100-N2G-040PE0
The MDD025C-N-100-N2G-040PE0 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. This brushless AC servo motor is designed for use with the manufacturer’s digital drive controllers, where it delivers finely regulated torque and speed to indexing tables, pick-and-place axes, and compact packaging equipment. In such systems, the unit converts timed current pulses from the inverter into controlled rotary motion, enabling closed-loop positioning and rapid velocity changes during continuous production. Its compact layout also suits machines that need precise motion in limited installation space.
At standstill the motor supplies a continuous torque of 0.90 Nm, allowing small loads to be held without thermal overload. During operation it can reach a nominal speed of 10,000 rpm, supporting high-cycle machinery that demands short move times. Accurate mounting is aided by a centering pilot diameter of 40 mm, while frame size code 025 identifies the motor platform used in this subfamily. Length code C indicates the longest stack in the 025 size, which increases copper volume for higher power density. Rotor position is reported through resolver feedback, providing reliable angle data under shock and electrical noise. Power and sensor leads are supplied on a connecting cable with a coupling unit for straightforward connection.
Standard dynamic balancing helps keep vibration low during rotation, and the housing follows the series' standard enclosure profile. The output shaft is machined with a keyway for positive coupling and protected by a shaft seal that helps block coolant splash and dust ingress. Only the A-side shaft end is present, which keeps the motor shorter and leaves the opposite end without a second output stub. All cabling emerges on the left, simplifying routing where right-hand clearance is limited. The motor ships without a blocking brake, so holding torque must be supplied electrically.
