Product Description:

The MDD025A-N-100-N2G-040GL1 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Engineered for digital drive controllers, it converts commanded current into precise mechanical rotation for compact handling units, pick-and-place axes, and similar automation tasks. This design lets the motor translate current commands into stable rotary motion for tightly coordinated motion sequences. Its high-speed capability and integrated feedback support closed-loop positioning where several axes must start, stop, and synchronize with repeatable accuracy.

It uses a centering diameter of 40 mm, so the flange mates accurately with machine plates. The power and feedback connectors are oriented on the left side, which can simplify cable routing when several motors face the same direction in a compact machine. Continuous torque at standstill is 0.33 Nm, indicating the sustained force the stator can produce without overheating during holding duty. At its rated operating point, the rotor reaches 10,000 rpm, which suits applications that demand very rapid indexing and short cycle times. A resolver provides resolver feedback so the controller can track rotor position during operation and maintain stable speed regulation. Standard dynamic balancing limits vibration, and the housing uses a standard uncooled aluminum frame. Power and sensor lines use keyed connectors, which help prevent incorrect mating.

A blocking brake is integrated and exerts 1.0 Nm of static torque to hold vertical loads when power is removed. The motor has a plain shaft, and the front bearing area is protected by a shaft seal that helps reduce the ingress of coolant or dust. Because there is no side B shaft end, the rear of the motor stays compact for closely spaced assemblies. The motor size is 025, and its compact frame helps keep rotor inertia low for short acceleration profiles.
