WEG Other models

The register lists here 375 versions from 0.75 to 160 kW, 2- to 8-pole, with efficiencies from 76 to 96.3% at full load and 73.5 to 96.3% at 75% load, protection classes from IP55 to IP66 and frame sizes from 80 to 355 (IEC). For 106 of the models the register shows the classification "2005 High Efficiency Level", roughly equivalent to class IE2; the majority carry no such classification.

Alongside ABB and Siemens, WEG is one of the volume manufacturers of industrial three-phase motors, and this collective page covers the broad middle ground of standard motors not assigned to any separately maintained range – from small units for pumps and fans to motors for compressors and conveying plant.

For used WEG standard motors the rating plate comes first: frame size, pole count, efficiency class and protection class must match the intended application. Beyond that comes an insulation resistance test of the winding, the condition of the bearings (running noise, bearing play, re-greasing ability on larger frames), free running of the shaft, the condition of the fan and fan cowl, and – for planned inverter operation – whether the winding insulation and bearings are rated for operation on a variable-frequency drive.
