KDA 3.1-100-3-LY0-U1

Product Description:

The KDA 3.1-100-3-LY0-U1 is part of Bosch Rexroth Indramat’s KDA Spindle Drives collection, shaped to handle jobs in bigger cabinet setups. Rated at 100 A, this drive doesn’t slow down when heavy current rolls in, and a 3-phase, 400 V AC input does the trick for powering higher-demand spindles found in machines or conveyors. Control is single axis so all the power is put behind one piece of moving hardware instead of getting split up. Feedback comes in from resolver or encoder, so real-time machine position never dips too far off. Standard in this series, a control cabinet mounting design helps with steady installs and saves space where the box gets crowded.

Internal air cooling, handled through a built-in fan, clears away any worries about heat causing slowdown. The housing holds up with an IP20 protection rating, which stops small bits and fingers from sneaking in but stays open enough to breathe with the fan system working. Connection is set up for SERCOS plus analog/digital lines, keeping comms open for controls or safety. Light touches like CE and UL (per variant) mean the checks for electrical safety clear most plant requirements easily.

This drive sits at about 10 kg and lines up at 383 x 74 x 213 mm, so getting it into an already loaded cabinet doesn’t chew up too much room. Metal sides and a compact layout hold firm over a lot of start and stop cycles in tough settings. Strong point for this unit is the continuous amperage on tap, working best in lines or machines that never really see a rest, including wood cutting, metal shaping, and bigger robotic actions where repeatability is the priority. Everything about this spindle drive puts reliable pushes and stops first, keeping breakdowns out of the day shift.
