The WE 1A100L1-4 is a three-phase induction motor. The rated output is 2.2 kW. The motor is four-pole, which at 50 Hz gives a synchronous speed of 1,500 rpm. The housing is frame size 100 L in foot-mounted form. The protection class is IP55. The efficiency is 81 per cent at full load, 81.8 per cent at 75 per cent load and 80.2 per cent at half load. Mounting arrangements to IEC 60034-7: B3, B5, B35, B14 and B34. The motor is built in China. The values are recorded in the Australian MEPS registration under the GEMS Determination 2012; measured to AS/NZS 1359.102.3:2000. Rated output across the WE range ranges from 0.75 to 160 kW; the 1A100L1-4 sits at the bottom of that range with 2.2 kW. Its immediate neighbours are the 1D90S-2 below it with 1.5 kW and the 1A100L-2 above it with 3 kW. 125 WE models are on record. The model is listed under Electric motors. 21 verified figures from 1 source are on file.

WE – other models: the collective page of three-phase motors from the Australian GEMS/MEPS register, 0.75 to 160 kW, 2- to 8-pole, IP55 throughout, Chinese manufacture, efficiencies up to 95.4%

This page gathers the three-phase motors registered under the short brand WE in the Australian GEMS/MEPS register that could not be assigned to a named range. Neither headquarters nor group ownership behind the short designation WE can be reliably determined from the register; what is confirmed is that all 125 models recorded here come from Chinese manufacture. The type codes follow the pattern 1A-frame size-additional digit-pole count, for example 1A100L-2 for a motor of frame size 100L with two poles; the prefix 1A is likely to denote a range or design variant, the precise content of which cannot be inferred from the register.

The register lists here 125 versions from 0.75 to 160 kW, 2- to 8-pole, with efficiencies from 72.1 to 95.4% at both full load and 75% load, all in protection class IP55 and frame sizes from 80 to 355 (IEC). No GEMS "High Efficiency Level" classification is recorded for any of the 125 models.

In the register, WE appears as a straightforward supplier of consistently IP55-rated standard motors for the Australian and New Zealand market; without confirmed manufacturer information, its market role can only be read from the register data itself.

For used WE motors, the usual checkpoints for standard motors 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 the rating plate – frame size, pole count and efficiency class – against the intended application. For inverter operation, check separately whether the winding insulation and bearings are rated for it, since the register contains no data on this.

Frequently asked questions

How much power does the WE 1A100L1-4 have?

The WE 1A100L1-4 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.
