Atlas Copco VSD280

The register lists here 113 versions with 2.2 to 132 kW, two- and four-pole, full-load efficiencies from 87.2 to 96.11% and at 75% load from 86.4 to 95.69%. Frame sizes run from 100 to 280 under IEC, mostly in protection rating IP55, alongside IP54, IP23 and IP56. China is recorded throughout as the manufacturing country, tested under the GEMS determinations of 2019 and 2012 with test methods B, 2-1-1B and A. For 98 of the 113 motors the High Efficiency Level classification is documented, though only 3 reach the 2005 level and 2 the 2018 level; the remaining 93 fall into neither class. Mounting code B5 dominates, alongside the IM3001 flange with support foot, B34, B35, B3 and IM1001.

The page thus shows the motor programme with which Atlas Copco drives part of its own compressor and blower manufacturing, while the manufacturer's large named ranges have their own register pages; competitors for compressed-air drives include Kaeser and Ingersoll Rand. The Australian GEMS certification shows that part of the programme is also approved for the Australia-Pacific market.

When buying used or replacing, what matters is bearing condition and a checked insulation resistance of the winding, visible overheating marks on the terminal box and fan cover, the condition of shaft and key, and a legible nameplate with frame size, pole count and efficiency class; for compressor drives it is also worth checking the fit to the specific compressor unit. Spares usually run through the Atlas Copco sales network.
