Product Description:

The MDD025C-N-100-N2G-040FA0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts controlled electrical input into rapid rotary motion for positioning axes in automated machinery. Its narrow frame and resolver interface make it suitable for light-duty tooling, pick-and-place heads, and small conveyor segments where high speed and accurate feedback are required. The compact format also helps reduce moving mass on small axes that rely on short indexing moves and quick direction changes.

It delivers a continuous standstill torque of 0.90 Nm, allowing the motor to hold or start loads without overheating during stationary operation. A nominal speed rating of 10000 rpm supports rapid cycle times when paired with a suitable drive. Electrical power and feedback are routed through a compact connector that faces side A of the housing, which helps simplify cable runs in tight machine spaces. The mechanical output uses a plain shaft, so couplings or pulleys mount directly without keys, which can help reduce runout at very high rotational speeds. These operating values help determine suitable load inertia and drive selection in high-speed axis applications.

A resolver provides resolver feedback for commutation and closed-loop velocity control, and this feedback method remains resistant to electrical noise. The centering pilot is 40 mm, which helps align the motor accurately with mounting flanges or gearbox interfaces. Size code 025 and length code C identify the compact stator stack used for this motor. The housing uses a standard unventilated build, the rotor is balanced to standard quality, and the shaft end is single-sided. Because the unit comes without a shaft seal and without a holding brake, added protection or external locking may be needed in washdown areas or on vertical axes.
