The ABB M3ARF/S100LD4 is a three-phase induction motor. The rated output is 3 kW. The motor is four-pole, which at 50 Hz gives a synchronous speed of 1,500 rpm. The rated voltage is 400 V. The housing is frame size 100. The protection class is IP55. The efficiency is 87.4 per cent at full load, 87 per cent at 75 per cent load and 86 per cent at half load. The motor weighs 29 kg. At full load it delivers 19.7 Nm. Mounting arrangements to IEC 60034-7: B3, B5, B35, B14 and B34. The motor is built in Spain. The values are recorded in the Australian MEPS registration under standard AS/NZS 1359.5:2004; measured to IEC 60034-2-1 (Edition 2.0). Rated output across the ABB range ranges from 0.75 to 185 kW; the M3ARF/S100LD4 sits at the bottom of that range with 3 kW. Its immediate neighbours are the M3MA 90 MB 2 below it with 2.2 kW and the M2BA 112 MB 4B above it with 4 kW. 2143 ABB models across 2 series are on record. The model is listed under Electric motors. 24 verified figures from 1 source are on file.

ABB M3ARF – register of low-voltage standard motors from ABB's M3 platform: 30 versions, 0.75 to 22 kW, 2- to 8-pole, IP55, 400 V, made in Sweden and Spain

The M3ARF range belongs to ABB's global M3 platform for three-phase low-voltage standard motors, through which the group formed in 1988 from the merger of ASEA and BBC standardises its IEC motors worldwide. The model designation follows the pattern M3ARF/S plus frame size and pole count, for example M3ARF/S132S4 for the four-pole 132S version or M3ARF/S160L8 for the eight-pole 160L version.

The register lists here 30 versions with 0.75 to 22 kW, two- to eight-pole, at a uniform mains voltage of 400 V. Full-load efficiencies range from 80.9 to 93.3% and at 75% load from 79.3 to 93.9%. Frame sizes run from 80 to 180 under IEC, all motors carry protection rating IP55, mounting codes range from B3/B5/B35 to combinations with B14 and B34; manufacturing is mainly in Sweden, with further output from Spain and Italy, tested to AS/NZS 1359.5:2004 with test method B.

In the lower and middle power range, M3ARF competes with the standard-motor ranges of Siemens and WEG for applications in pumps, fans, conveyors and small compressors; manufacturing in Sweden and Spain places the range in the European core of ABB's low-voltage motor programme.

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, the condition of shaft and key, and a legible nameplate with frame size, pole count and efficiency figure. Spares and rewind service run through ABB's motor service network.

Frequently asked questions

How much power does the ABB M3ARF/S100LD4 have?

The ABB M3ARF/S100LD4 delivers 3 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.
