Fantech Y2AE90S-2 B5

The register lists here 76 versions with 0.75 to 11 kW, two- to eight-pole, full-load efficiencies from 71.9 to 89.4% and at 75% load from 71.2 to 89.9% — consistently smaller drives in the lower power range. Protection rating is mostly IP55, occasionally supplemented with IP00 or IP01; frame sizes run from 80 to 160 under IEC. Manufacturing is overwhelmingly in China, testing followed consistently the 2019 GEMS determinations with test method 2-1-1B. For 25 of the 76 motors a High Efficiency Level test is documented, though none reached either level; for 68 motors a motor family is additionally recorded with four identical versions per frame size, apparently differing by mounting code.

With its focus on smaller outputs up to 11 kW, the page shows the typical drive programme for fans that Fantech needs in its own residential and commercial ventilation range; competitors for fan drives include Systemair and Ebm-Papst.

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; since none of the tested motors reaches a High Efficiency Level, for continuous duty it is worth comparing against newer IE2/IE3 fan drives. Spares run through the Fantech sales network.
