Product Description:

The MDD025A-N-100-N2K-040GE0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It delivers precise rotary motion in compact automation modules such as light pick-and-place axes, labeling spindles, and miniature gantries. Closed-loop operation supports controlled acceleration, velocity, and position so machine cycles remain consistent under changing load conditions. Its compact format also suits installations where short motor length and stable motion control are both important.

Internally, the rotor is balanced to the standard grade, which helps reduce radial forces on adjacent bearings during high-speed operation. A centering diameter of 40 mm aligns the frame with servo flanges, while the size 025 housing with length code A keeps the motor compact. The winding provides a continuous standstill torque of 0.33 Nm, and the magnetic circuit supports a nominal shaft speed of 10,000 rpm for fast indexing duty. Position data are supplied by an integrated absolute encoder, and the drive also receives coarse-angle information through resolver feedback during startup. Cables exit on the left side of the stator, which can simplify routing in narrow enclosures and reduce congestion around nearby machine elements.

Power and feedback conductors are supplied through a connecting cable with a coupling unit, so the motor does not use a terminal box. The assembly is delivered without a blocking brake, which keeps rotating mass lower for continuous-duty applications that do not require holding torque at standstill. A factory-installed shaft seal helps limit the ingress of coolants and dust during operation. Torque is transmitted through a plain shaft with no side B shaft extension, which helps keep the drive train compact where motors are mounted close to adjacent components.
