Product Description:

The MDD025A-N-100-N2G-040GA1 is a compact servo unit manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts electrical commands into rapid mechanical motion, providing tight position and velocity control for small automation axes and auxiliary machine functions.

The motor seats against mounting fixtures with a centering diameter of 40 mm, ensuring concentric alignment and minimal radial run-out. When held motionless it can supply a continuous shaft torque of 0.33 Nm, enough to counter modest process loads without overheating. A blocking brake is integrated and secures the rotor with up to 1.0 Nm of holding torque, permitting safe power-off stops on vertical or indexing axes. For dynamic operation the rotor is wound to achieve a nominal speed of 10000 min⁻¹, allowing high linear feed rates when coupled to low-ratio belt or screw transmissions.

Position feedback is generated by a resolver feedback device, giving absolute angle data for closed-loop drives even after power interruptions. Power and signal conductors exit on Side A through a single connector, simplifying cable routing in dense cabinet layouts. The stator stack corresponds to length code A, keeping overall mass low while maintaining thermal surface area for continuous duty. A plain shaft with an installed shaft seal prevents lubricant egress and protects internal bearings from airborne contaminants during extended service cycles.

Wake Industrial offers a 1-year warranty on this model, can arrange same-day shipping for time-critical orders, and provides a free chat tool for questions about fault codes or type codes.
