In the 3 to 15 kW power range, the YE2/YE3 programme covers the classic demand of small and medium industrial drives for pumps, fans and conveyors, which numerous Chinese manufacturers offer in parallel under their own brand names.

When buying used, 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 the YE2 or YE3 designation. Spares are usually available independent of manufacturer thanks to the widely used frame size.
