Product Description:

The MDD025C-N-100-N2G-040PA0 is a small-frame AC servo motor engineered by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a drive element for digital drive controllers, the unit converts controlled electrical input into precise rotational motion for indexing tables, pick-and-place heads, and other high-speed axes in industrial automation. Its compact 025 frame and C length code support installations where limited space and rapid acceleration are equally important. Because it is intended for digital drive controllers, motor current can be regulated closely during acceleration, deceleration, and holding phases. That helps short-cycle machinery maintain accurate motion profiles during repetitive operation.

At standstill, the motor can supply 0.90 Nm of continuous torque, which indicates the maximum static load it can hold without exceeding thermal limits. Once energized, it reaches a nominal speed of 10000 rpm, allowing fast positioning cycles when coupled to a suitable inverter. Mechanical alignment is helped by a centering diameter of 40 mm, which helps the motor seat accurately on machine plates. All power and feedback conductors exit on Side A, and the factory-fitted connector interface allows quick electrical connection. The cable exit on Side A can also simplify routing where the motor is mounted close to guards, slides, or adjacent machine components. The housing follows the general MDD outline, so it fits compact machine layouts that use standardized mounting space.

The motor is supplied without a blocking brake, so holding torque must come from the drive or an external clamp when the axis is parked. Rotor position is reported through resolver feedback, which gives the controller reliable angle information across the speed range. Resolver-based feedback is also well suited to industrial motion systems because it remains stable under vibration and changing temperatures. Torque is transmitted through a hardened keyway shaft, and the shaft includes a shaft seal to help keep lubricant in place and contaminants out. The sealed shaft entry helps protect internal parts in environments where dust or light contamination may be present.
