Product Description:

The MDD025B-N-100-N2G-040GE1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Built for digital drive controllers, it transforms precisely metered current into accurate shaft rotation that supports fine-resolution positioning tasks in automated machinery. Its compact frame and wiring layout help the unit fit near sensors, actuators, and adjacent motion components where installation space is limited. This arrangement makes the motor suitable for tightly packed axes that still require responsive and repeatable motion.

At a nominal speed of 10,000 rpm, the rotor can sustain a continuous standstill torque of 0.60 Nm, giving the drive a predictable margin for holding and low-speed moves. Loss of mains power is managed by a blocking brake that delivers 1.0 Nm of static torque so vertically mounted loads can remain stationary. Mounting concentricity is set by a 40 mm centering diameter, and the rotor-stator assembly is balanced to the standard grade to help keep vibration within normal servo limits at high speed. The power and feedback leads exit on the left side through a connecting cable with a coupling unit, which supports orderly cable routing and reduces strain on the connection.

The motor uses frame size 025 and length code B, producing a short body that helps reduce axis mass for rapid acceleration. Motion data are returned through resolver feedback, allowing closed-loop control when the axis changes speed or position quickly. A plain shaft is supplied on the drive end, while the opposite face remains undrilled to save space and inertia. Contaminants are blocked by a shaft seal, which helps keep fine dust or stray coolant away from the bearings. The aluminum housing also helps keep the assembly light for compact motion systems.
