Product Description:

The MDD025A-N-100-N2G-040GD1 is a compact member of the Bosch Rexroth Indramat MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it provides closed-loop rotary motion for light-duty automation axes that need rapid acceleration and accurate positioning. The motor’s small frame and standard housing allow it to fit into tight machine spaces while still delivering the torque required for feeders, test fixtures, and miniature conveyors. Its compact size also suits indexing modules and small handling units where low moving mass and repeatable positioning are important.

This model reaches a nominal speed of 10,000 rpm, enabling high cycle rates when paired with appropriately rated inverters. At standstill it can generate 0.33 Nm continuously, so it can support light holding duty during dwell periods without overheating. A holding brake is integrated, and its static capacity of 1.0 Nm secures the shaft when power is removed, which helps prevent unwanted movement while the axis is idle. Position feedback is supplied by resolver feedback, which provides analog sine-cosine signals that remain tolerant of electrical noise and support stable control across the speed range. The centering register measures 40 mm, providing the alignment reference for flange mounting and helping maintain concentric rotation relative to the driven mechanics.

Cabling exits on Side B, so wiring can be routed away from moving parts and kept clear of nearby machine hardware. Power and sensor lines are provided through a connecting cable with coupling unit that mates directly to standard drive harnesses and supports orderly cable routing in compact installations. The output uses a plain shaft, which simplifies coupling to precision gearheads, clamp hubs, or belt pulleys without key machining. Contaminant ingress at the interface is limited because the motor is built with a shaft seal. Standard balancing helps reduce vibration during operation and supports smooth running in small servo-driven assemblies.
