The register lists here 6 versions with a rated output of 37 kW, all 4-pole, at a voltage of 415 V. Full-load efficiency ranges from 93.6 to 94.7%, and at 75% load from 93 to 94.6%. Frame sizes run from 200 to 225, protection ratings from IP55 to IP66. Testing mostly followed AS/NZS 1359.5:2004, with one motor tested under the 2012 GEMS determination.
At 37 kW, the K40 range sits in the upper industrial-motor segment used for pumps, compressors and heavy conveying equipment; WEG ranks alongside ABB and Siemens among the major suppliers in this power range. The wide range of mounting codes, from B3 through B6, B7 and B8 to the vertical forms V1 to V36, allows almost any mounting position.
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, and a legible nameplate with frame size, pole count and protection rating. On EX versions, the integrity of the explosion-proof housing and cable entries should also be checked. Spares and support run through the WEG sales network.

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.
