Product Description:

The MDD025A-N-100-N2G-040FL1 is a synchronous servo unit manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is intended for tightly regulated axes in assembly machines and semiconductor handlers. The model is delivered with a standard housing that simplifies cabinet mounting, and its rotor is factory balanced to the standard grade for vibration-controlled operation. Its compact form suits high-cycle positioning tasks where space and mass are constrained. This layout is useful on light, fast-moving axes that require accurate starts, stops, and short indexing moves.

The electrical output characteristics center on a nominal speed of 10,000 rpm, giving the drive ample speed range for light mechanical loads. At standstill, it can deliver 0.33 Nm of continuous torque, so the servo maintains position under static demand without overheating. A blocking brake is integrated, and its static holding capacity is rated at 1.0 Nm, preventing back-driving when the controller is de-energized. For positional feedback, the rotor carries resolver feedback, enabling analog angle detection over the full speed range. The front flange provides a centering pilot of 40 mm, which aligns the motor precisely on gearboxes or mounting plates and helps limit radial runout.

Electrical and signal terminations exit on the left side through a keyed industrial connector, so cable routing can remain inside protective cable chains. This side-exit arrangement can help keep wiring clear of adjacent moving components in narrow machine layouts. With a length code of A and frame size 025, the motor occupies minimal axial depth while still matching standard MDD flanges. The drive-train interface uses a plain shaft that mates directly with clamp couplings. There is no secondary shaft on side B, and the shaft area is supplied without a shaft seal, so the motor is intended for clean, enclosed environments where liquid ingress is controlled.
