The Brook Crompton WM2-DF112MT-6 is a three-phase induction motor from the Brook Crompton range. The rated output is 2.2 kW. The motor is six-pole, which at 50 Hz gives a synchronous speed of 1,000 rpm. The housing is frame size 112 M in foot-mounted form. The efficiency is 81.9 per cent at full load, 77.3 per cent at 75 per cent load and 73.2 per cent at half load. The motor weighs 55.2 kg. At full load it delivers 22.1 Nm. Stated countries of manufacture: China and Poland. The values are recorded in the Australian MEPS registration under the GEMS Determination 2019; measured to AS/NZS 1359.102.3:2000. Rated output across the Brook Crompton range ranges from 0.75 to 160 kW; the WM2-DF112MT-6 sits at the bottom of that range with 2.2 kW. Its immediate neighbours are the WM2-DF90SMX-2 below it with 1.5 kW and the T-D132S above it with 3 kW. 161 Brook Crompton models are on record.

Brook Crompton – other models: the collective page of three-phase motors outside the named ranges from the Australian GEMS/MEPS register, 0.75 to 160 kW, 2- to 8-pole, Polish-Chinese manufacture, efficiencies up to 96.2%

This page gathers the Brook Crompton three-phase motors the register could not assign to a named range, from the Australian GEMS/MEPS registration database for electric motors. Brook Crompton is a long-established British electric motor brand that today belongs to the Chinese drives group Wolong. The register lists several manufacturing countries at once for most models, with an emphasis on Poland and China, alongside mentions of the United Kingdom and India as further, partly historical, manufacturing locations. The type codes follow a pattern of prefix, range letter and frame size, for example A-EF100L, T-D100L or W-D100L; the prefixes A, T and W distinguish separate execution lines within the same frame-size range.

The register lists here 161 versions from 0.75 to 160 kW, 2- to 8-pole, with efficiencies from 72.4 to 96.2% at full load and 72.4 to 96.3% at 75% load, protection classes mostly between IP54 and IP66, and frame sizes from 80 to 355 (IEC). No GEMS "High Efficiency Level" classification is recorded for any of the 161 models.

As a Wolong brand, Brook Crompton represents the continuation of British electric motor tradition under Chinese group ownership, with manufacturing today concentrated mainly in Poland and China; the models gathered here represent the broad range outside the separately maintained series.

For used Brook Crompton motors, the usual checkpoints apply: measure the winding's insulation resistance, check the bearings for running noise and play, check the shaft turns freely, assess the condition of the fan and fan cowl, and match frame size, pole count, protection class and efficiency class on the rating plate against the intended application. For inverter operation, check separately whether the winding insulation and bearings are rated for it, since the register provides no data on this.

Frequently asked questions

How much power does the Brook Crompton WM2-DF112MT-6 have?

The Brook Crompton WM2-DF112MT-6 delivers 2.2 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.
