KDA 3.1-100-3-LQI-W1

Product Description:

The KDA 3.1-100-3-LQI-W1 spindle drive from Bosch Rexroth Indramat belongs to the KDA Spindle Drives family, with a setup meant to stay steady under pressure. Rated current lands at 100 A, and what stands out is the liquid-cooled (LQI) design pulling heat down fast, which is better for places where air cooling doesn't keep up. Cabinet mounting, all set for vertical position, fits right in when there’s not much room left sideways on the control wall. This model connects up on the main line with a 400–480 VAC supply, a pretty standard range for big installations.

Running in a stressed-out plant, the IP20 protection class on this spindle drive mostly shields from fingers or bigger parts, though it’s not for wet spaces. For jobs needing more ways to connect and measure, this unit supports both analog and digital control interfaces alongside access by like INTERBUS or optional SERCOS links. The maximum power dissipation isn't rigid and stretches between about 50 to 100 W per axis, most times it depends on workload and application, so it doesn’t push things to their limit for no reason. Built in for the control signals, U/V/W inputs give another step in wiring options that most installers like.

With a layout designed for three axes, the KDA 3.1-100-3-LQI-W1 fits setups targeting more than simple basic movement. Feeds on 24 VDC (nominal) to keep field circuits ready and safe, matching after hours work too. Safe mounting height can be set at up to 1000 m with no derating, so it’s also workable for facilities off the usual flatland. Packing it all together, this spindle drive steps in when automation asks for quiet, steady, and heat-controlled motion, serving metal shops, industrial lines, even spots known for vibration that shakes less rugged gear apart.
