Product Description:

The MDD025A-N-100-N2G-040MB0 is a compact synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. When coupled to a digital drive controller, it provides high-speed rotary motion for pick-and-place tables, small conveyors, and light tooling axes that require repeatable positioning. Its resolver supplies real-time rotor data to the controller, and the motor uses standard Rexroth mounting geometry for straightforward installation in existing automation frames. Its compact format also suits small machine sections where fast indexing and consistent motion are important.

With a continuous standstill torque of 0.33 Nm, the size 025 frame can hold modest loads without thermal derating, even when the shaft is at rest. During operation, the rotor sustains a nominal velocity of 10000 rpm, giving short acceleration times in systems that cycle rapidly. A centering diameter of 40 mm helps align the housing concentrically to the machine plate and limits runout. Power and feedback exit on Side B, and the single circular connector simplifies cable routing at one end of the motor. Internal components are balanced to the standard grade so the assembly remains suitable for high-speed operation.

The resolver interface returns rotor position signals to the controller through resolver feedback, which uses a transformer-based design that resists electrical noise. Torque is transmitted through a ground shaft with a keyway, which helps prevent slip between the motor and the coupling hub. For applications that rely on external holding devices, the unit is supplied without a blocking brake, which reduces inertia and maintenance points. An IP-tight front bearing cover is omitted, so the motor operates without a shaft seal to minimize friction. The motor body uses a standard housing style that matches other MDD models in the series.
