Product Description:

The MDD025A-N-100-N2G-040GC1 is a small-frame synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Built to work with digital drive controllers, the unit supplies precise rotary actuation for tasks such as light pick-and-place modules, dosing pumps, and auxiliary axes in machine tools. Its compact 025 size and A-length housing make it suitable for installations where space and mass must be minimized without sacrificing dynamic response.

The motor reaches a nominal speed of 10000 rpm, allowing rapid indexing cycles when paired with high-frequency control signals from the drive. At standstill, it can deliver a continuous torque of 0.33 Nm, enough to hold lightweight loads against static friction while still meeting the thermal limits of the standard housing. An integrated blocking brake supplies a holding capacity of 1.0 Nm. This spring-applied device prevents back-driving when the system is de-energized. Position and velocity are reported to the controller by resolver feedback, which tolerates elevated temperatures and electrical noise common in servo cabinets. Mechanical power is transmitted through a plain shaft, simplifying coupling to precision gearheads or direct-drive fixtures without keyways.

A centering diameter of 40 mm ensures concentric seating in the machine frame and helps limit runout during high-speed operation. All power and feedback leads exit on side A, so cable routing can remain on one face of the enclosure. The motor ships with a connecting cable with coupling unit, and this plug-in interface allows removal without disturbing sealed cable entries. A dedicated shaft seal blocks coolant splash and airborne particles from reaching the front bearing. This helps protect the bearing area during prolonged duty cycles and supports reliable operation in compact machine layouts.
