KDA 3.1-100-3-AYI-W1

Product Description:

The KDA 3.1-100-3-AYI-W1 module comes from the KDA Spindle Drive lineup by Bosch Rexroth Indramat. This drive handles a nominal current of 3.1 A and fits well in tight installations due to its compact form. It measures around 390 x 103 x 227 mm and uses a simple W1 mounting configuration. Cooling is handled through an air-cooled system, which removes heat efficiently without the need for liquid components. Weight stands at roughly 7.5 kg, which makes handling straightforward during cabinet builds.

With a protection level of IP20, the unit stays protected in closed electrical enclosures but isn’t made for open or dusty environments. It performs best in a controlled space with temps between 0 to +45°C. Input frequency typically falls at 50/60 Hz, making it compatible with general industrial power feeds. Voltage sits at 100 V, matching the internal power needs of most standard machine setups.

Drive configuration includes an AYI-type feedback interface, which likely supports analog or incremental encoder systems. That makes it a good fit for servo motor connections that need accurate speed or position feedback without digital-only restrictions. Built for three-phase systems, this spindle drive offers reliable communication with supported motors in lathes, mills, and material feed systems. The enclosure and internal layout are designed for steady output without frequent resets or overheating. Component layout helps with heat flow, and the air movement design avoids buildup around heat-generating parts. As part of the broader KDA line, this model fits into larger automation systems that demand balance between space-saving form and dependable electrical behavior. Designed to stay stable under typical machine loads, the KDA 3.1-100-3-AYI-W1 brings solid drive performance where tight size and decent feedback matter most.
