YE3 Series IE3 Low-Voltage Three-Phase Induction Motor

The YE3 series is the IE3 high-efficiency replacement for the older Y, Y2 and YE2 ranges that most plants still run. Same mounting dimensions, same shaft height, same terminal box position - the motor drops in where the old one came out, with a lower current draw at the same output.

Typical duty: centrifugal pumps, fans and blowers, conveyors, compressors, mixers and machine tools, indoors or under a simple canopy. Frames up to 160 are aluminium, from 180 up they are cast iron, which keeps the larger sizes stiff enough for belt-driven and direct-coupled loads. Winding is Class F with a B temperature rise, so there is thermal margin for a 1.15 service factor or for a slightly higher ambient than the nameplate states.

For each order we confirm four things before release: the required output and pole number, the site voltage and frequency, the mounting arrangement, and whether the driven machine needs a brake, encoder, separate cooling fan or tropicalised winding. Test reports with efficiency, current and no-load losses are issued against the serial number, and a nameplate photo is sent before packing on request.
