Baldor – other models: the collective page of MEPS-registered three-phase motors outside the named ranges, an ABB subsidiary since 2011 based in Fort Smith, Arkansas, frame sizes 56 to 315, 0.75 to 185 kW
This page gathers the Baldor three-phase motors the Australian energy-efficiency register could not assign to a named range. Baldor Electric, founded in 1920 in St. Louis and now headquartered in Fort Smith, Arkansas, has been an ABB subsidiary since the 2011 takeover and still trades in the North American market under the Baldor or Baldor-Reliance name. The identifiers in the register, such as 07H531W722G2 or 10K552X209G1, are mostly serial numbers of individual production lots rather than type codes; recognisable range names only appear in the motor-family field, led by the metric M4 range (M4A/C, M4AC) for IEC frame sizes.

The register lists here 814 versions with 0.75 to 185 kW, two- to eight-pole, full-load efficiencies from 76.4 to 96.3% and at 75% load from 75.3 to 96.4%. Protection is overwhelmingly IP55 (657 of 814), alongside IP54, IP44, IP65, IP56 and IP23; frame sizes run from 56 to 315, and the mounting form is broad – 308 motors purely in B3 and a further 200 versions in the full B3/B5/B14/B34/B35 set. The USA (459) and China (355) are recorded as manufacturing countries. Testing mostly followed the 2012 GEMS determination and AS/NZS 1359.5, with test methods B and A; only 198 of the 793 classified motors reach a High Efficiency Level (182 the 2005 level, 16 the 2018 level), the rest remain unclassified.
Baldor is one of the long-established US motor makers and, through ABB, now part of the world's largest supplier of industrial motors; in North America the brand remains positioned independently, with a focus on rugged motors for pumps, fans and conveying plant in industry and agriculture.
When buying used, durability and winding-wire quality typically matter on the older motors made in the USA, bearing and fan-cover condition on the newer Chinese-made lots; a measured insulation resistance, a legible nameplate with frame size and efficiency class, and, on IP55 motors used outdoors, the condition of the seals at the terminal box and shaft lead-through are important. Spares and service run through the Baldor/ABB network.

The Baldor M4C280S-2B3C delivers 75 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.
