The 1H180M-2 from Western Electric is a three-phase induction motor. The rated output is 22 kW. The motor is two-pole, which at 50 Hz gives a synchronous speed of 3,000 rpm. The rated voltage is 400 V. The housing is frame size 180 M in foot-mounted form. The protection class is IP55. The efficiency is 92.3 per cent at full load, 92 per cent at 75 per cent load and 89.9 per cent at half load. The motor weighs 199 kg. At full load it delivers 71.39 Nm. The motor is built in China. 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 Western Electric range ranges from 0.75 to 185 kW; the 1H180M-2 sits at the bottom of that range with 22 kW. Its immediate neighbours are the 1H225S-8 below it with 18.5 kW and the 1H200L-4 above it with 30 kW. 80 Western Electric models are on record.

Western Electric – other models: the collective page of MEPS-registered three-phase motors outside the named ranges, frame sizes from 90, 0.75 to 185 kW, 2- to 8-pole, 400 V, IP55

This page gathers the three-phase motors carried in the Australian energy-efficiency register under the Western Electric brand, which the register does not assign to a named range. The Western Electric brand carried in this register has no connection to the historic American telephone and electrical group of the same name; Australia's GEMS programme and its Levels are independent of the IEC IE1-to-IE4 classes. The type designations follow the scheme 1H with IEC frame size, a foot-form letter and pole count, e.g. 1H100L-2 or 1H160M-6.

The register lists here 80 versions with 0.75 to 185 kW, two- to eight-pole, all rated for 400 V. Full-load efficiencies run between 73.46 and 95.82%, and at 75% load between 73.62 and 95.74%. All 80 motors are built to protection rating IP55, frame sizes start at 90 under IEC and reach into the upper three-digit range; manufacturing is consistent in China, testing followed AS/NZS 1359.5:2004 with test method B. For 3 of the 80 motors the High Efficiency Level 2005 is documented, the remaining 77 reach no classification. Mounting codes cover a very wide spectrum from B3 and B5 through B14, B6, B7, B8 to combined foot-flange forms and the vertical forms V1, V3, V5, V6, V18, V19.

The page thus covers a broad IEC standard-motor programme without significant efficiency certification; the wide variety of mounting codes points to a catalogue programme adapted to very different installation situations in pump, fan and conveyor technology.

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 class; given the large number of mounting variants, it is especially worth checking the exact mounting code against the intended installation before buying. Spares depend on the distribution channel.

Frequently asked questions

How much power does the Western Electric 1H180M-2 have?

The Western Electric 1H180M-2 delivers 22 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.
