With the M2BAX 160 MLB 4, ABB offers a three-phase induction motor in the M2BAX series. 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 160. The protection class is IP55, IP56, IP65 and IP66. The efficiency is 92.5 per cent at full load, 92.7 per cent at 75 per cent load and 92 per cent at half load. Mounting arrangements to IEC 60034-7: B3, B5, B8, B35, V1, V3, V5 and V6. Stated countries of manufacture: Finland, Poland, China and India. The values are recorded in the Australian MEPS registration under the GEMS Determination 2019; measured to IEC 60034-2-1 (Edition 2.0). The M2BAX series covers 61 models. Rated output within it ranges from 0.75 to 184.99 kW; the M2BAX 160 MLB 4 sits at the bottom of that range with 15 kW. Its immediate neighbours are the M2BAX 160 MLB 6 below it with 11 kW and the M2BAX 160 MLC 2 above it with 18.5 kW. 2141 ABB models across 12 series are on record.

ABB M2BAX – three-phase motor range, per manufacturer logic the predecessor generation to the M3 range, manufactured in Finland, Poland, China and India, frame sizes 80 to 355, 0.75 to 185 kW

This page gathers the M2BAX range motors from ABB as listed in the Australian energy-efficiency register. M2BAX belongs, per manufacturer logic, to the older generation of ABB's IEC low-voltage motors that preceded the current M3 range (see the separately listed M3BP and M3JM ranges). The type designations, such as M2BAX 160 MLA 2, follow the scheme M2BAX <frame size> <length+variant> <pole count>.

The register lists here 61 versions with 0.75 to 185 kW, two- to six-pole, full-load efficiencies from 82.6 to 96.3% and at 75% load from 82.5 to 96.6%. Frame sizes run from 80 to 355, all motors are recorded with the full IP55/IP56/IP65/IP66 protection combination. The combination of Finland, Poland, China and India dominates the manufacturing countries (45 of 61), with Sweden appearing singly. Testing followed the 2019 GEMS determination throughout, mostly with test method A (58); of 61 motors, 57 reach the 2005 High Efficiency Level (roughly IE2) and 3 the 2018 level (roughly IE3), only 1 stays unclassified.

As an older ABB range, M2BAX still covers a broad field of industrial applications, from pumps through fans to conveying plant, with an unusually high proportion of classified High Efficiency motors for ABB.

When buying used, what matters is bearing condition and a checked insulation resistance of the winding, the condition of shaft, key and fan cover, and a legible nameplate with frame size, mounting form and efficiency class; inverter suitability is given on most M2BAX models but should be confirmed individually from the nameplate. Spares run through the ABB service network.

Frequently asked questions

How much power does the ABB M2BAX 160 MLB 4 have?

The ABB M2BAX 160 MLB 4 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.
