WEG K12 – three-phase motor from the Brazilian manufacturer in Jaraguá do Sul: frame size 90 to 100, four-pole, 1.5 kW, IP55, five build variants
K12 is a three-phase motor range from WEG, the Brazilian electric motor manufacturer headquartered in Jaraguá do Sul in Santa Catarina. The five versions listed carry the suffixes ALBRKLE2, ALE2, EXDE2, EXNE2 and STDE2, marking different build variants within the range.

The register lists five versions with 1.5 kW rated output throughout, four poles, and an efficiency span of 85 to 85.6% at full load and 85.1 to 85.2% at 75% load. Frame size ranges from 90 to 100, protection is IP55 throughout, and the voltage entry is 415 V. Manufacturing takes place in Brazil, tested under the AS/NZS 1359.5:2004 standard, using test method B throughout. The mounting code covers practically the whole IEC spectrum across all five versions, from foot forms B3 to B8, through flange forms B14, B34 and B35, to vertical forms V1 to V36.
With five different build variants at almost identical output, K12 covers an output step in the lower band of WEG's broad programme of IEC standard motors, through which the group ranks among the largest electric motor manufacturers worldwide.
When buying used or swapping, check bearing condition, insulation resistance of the winding, visible overheating traces on the terminal box and fan cover, and a legible nameplate showing frame size, pole count and build variant. Given the wide choice of mounting codes, it is worth checking before purchase which of the many bolt patterns actually fits the installation point. Spare parts and support run through the WEG sales network.

The WEG K12 EXNE2 delivers 1.5 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.
