The WEG 02018ET3ER256TC-W22 is a three-phase induction motor from the WEG range. The rated output is 15 kW. The motor is four-pole, which at 50 Hz gives a synchronous speed of 1,500 rpm. The housing is frame size 256TC. The protection class is IP56. The efficiency is 92.8 per cent at full load, 93.4 per cent at 75 per cent load and 93.2 per cent at half load. Mounting arrangements to IEC 60034-7: B5, V1, V3 and V19. Stated countries of manufacture: Mexico and Brazil. The values are recorded in the Australian MEPS registration under the GEMS Determination 2019; measured to IEEE 112-B(USA). Rated output across the WEG range ranges from 0.75 to 160 kW; the 02018ET3ER256TC-W22 sits at the bottom of that range with 15 kW. Its immediate neighbours are the W21 K29/1TAC below it with 11 kW and the K33 EXDE2 above it with 18.5 kW. 433 WEG models across 12 series are on record.

WEG – other models: the collective page of three-phase motors outside the named ranges from the Australian GEMS/MEPS register, 0.75 to 160 kW, 2- to 8-pole, IEC frame sizes 80 to 355, efficiencies up to 96.3%

This page gathers the WEG three-phase motors the register could not assign to a named range, recording them individually from the Australian GEMS/MEPS registration database for electric motors. WEG was founded in 1961 in Jaraguá do Sul, Brazil, the name taken from the initials of its three founders, and the manufacturer is today one of the world's largest builders of electric motors. The models recorded here come almost entirely from Brazilian production. The type plates follow noticeably different schemes: codes such as 160M appear to name the IEC frame size directly, while ranges such as K10A or K11 mark a product family with protection- and ignition-safety variants (ALE, EXNE, EXDE, STDE).

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.

Frequently asked questions

How much power does the WEG 02018ET3ER256TC-W22 have?

The WEG 02018ET3ER256TC-W22 delivers 15 kW.

What to check before buying

  • Match the data plate against the order: frame size, mounting and rating have to agree.
  • Check the ingress rating against the installation site — outdoors or in dust the demands differ.
  • Hold the mounting form and dimensions against the existing seat before ordering.
  • The pole count sets the speed — when replacing an older unit, compare this first.
  • For used units, ask about winding condition and bearing play.
  • Ask about parts availability for this series — the running costs hang on it.
