Product Description:
The Rexroth Indramat makes the KDA 3.2-100-3-APS-W1 AC main spindle drive that can handle speeds within ±10 V and has an extra input for a 1 V sine encoder. The stable operation is supported by the heatsink and blower assembly's configuration, which allows for efficient heat dissipation. Under constant load, the forced cooling system keeps the temperature stable.
The dimensions of the KDA 3.2-100-3-APS-W1 spindle drive are 525 mm in height, 390 mm in width, and 355 mm in depth. The width of the heatsink is 160 mm when it is not equipped with an air duct and 185 mm when it is equipped with an air duct. The depth of the air duct is 25 mm. The horizontal mounting hole distances are 345 mm, and the vertical mounting hole distances are 160 mm. The dimensions of the blower unit are 169 mm in width and 88 mm in depth. There is an 80 mm gap between the blower and the enclosure. A 185 mm wide air duct is available. The blower, with the mounting frame, has a total height of 490 mm.
The main spindle drive AC uses 300 V and has a current rating of 100 A. The blower unit is 4.2 kg in weight, while the mounting accessories are 1.7 kg. For forced cooling, the drive makes use of a 115 V AC supply voltage at 50-60 Hz for the heatsink fan. The standard power infrastructure compatibility is guaranteed by the supply voltage standards. The design of the KDA 3.2-100-3-APS-W1 AC main spindle drive allows for accurate control of the spindle by utilizing encoder feedback and analog speed input. Consistent performance in automation processes is ensured by configuring all requirements accordingly.
