Product Description:

The MDD025A-N-100-N2G-040GC0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies rotational energy to axes that demand rapid acceleration and stable velocity in automated lines, pick-and-place modules, and small tooling spindles. It converts commands from a Rexroth servo amplifier into precise rotary motion while remaining compatible with the power and feedback connections used in this motor family. Its compact format makes it suitable for installations where available space is limited but controlled motion is still required.

At standstill, the motor develops a continuous torque of 0.33 Nm, which provides steady holding force for light loads without exceeding thermal limits. During operation, the rotor can reach a nominal speed of 10000 rpm, which supports high throughput on short-stroke axes and compact spindle tasks. Position and velocity are controlled through resolver feedback, which sends analog sine-cosine signals to the drive for closed-loop operation. The unit is supplied without a blocking brake, so any holding function must come from the application or an external mechanism. Mechanical power is transferred through a plain shaft, which avoids keyway stress and supports straightforward coupling alignment. Standard dynamic balancing helps reduce vibration across the speed range, and the aluminum housing supports even heat dissipation during continuous use.

The mounting pilot has a centering diameter of 40 mm, which supports accurate alignment with flanges or gearheads. The electrical and feedback connections are located on Side A, which allows cable routing toward the drive cabinet in many machine layouts. A shaft seal at the output end helps limit the entry of particles and the escape of lubricant during operation. The motor uses frame size 025 with length code A, giving it a compact body for narrow axis compartments. It is supplied with a standard housing and a single-ended shaft, so it can fit into compact motion assemblies without requiring extra mounting space.
