The Wonder ZWE180L6 is a three-phase induction motor built by Wonder. The rated output is 18.5 kW. The motor is six-pole, which at 50 Hz gives a synchronous speed of 1,000 rpm. The housing is frame size 180 L in foot-mounted form. The protection class is IP55, IP56 and IP66. The efficiency is 90.5 per cent at full load, 91.1 per cent at 75 per cent load and 89.5 per cent at half load. The motor is built in China. The values are recorded in the Australian MEPS registration under the GEMS Determination 2012; measured to IEC 60034-2-1 (Edition 2.0). Rated output across the Wonder range ranges from 0.75 to 180 kW; the ZWE180L6 sits at the bottom of that range with 18.5 kW. Its immediate neighbours are the WEA 180L6 below it with 15 kW and the SWE 180L4 above it with 22 kW. 80 Wonder models across 5 series are on record.

Wonder – other models: the collective page of MEPS-registered ZWE three-phase motors outside the named ranges, frame sizes 180 and 225, 18.5 to 55 kW, two- and six-pole, multi-voltage up to 690 V

This page gathers the Wonder three-phase motors the Australian energy-efficiency register could not assign to a named range. The designations recorded in the register, ZWE180L6 and ZWE225M2, follow a scheme of a range code, the IEC frame size (180, 225), build length (L, M) and pole count at the end (6, 2).

The register lists here 2 versions with 18.5 to 55 kW rated output, six- or two-pole, for a multi-voltage supply of 400, 415, 440 and 690 V, with full-load efficiencies from 90.46 to 93.51% and at 75% load from 91.1 to 93.74%. Protection ranges from IP55 through IP56 to IP66, frame sizes from 180 to 225; the mounting code covers a broad spectrum of installation positions with B3, B5, B6, B7, B8, B35 and the vertical forms V1, V3, V5, V6 and V36. Manufacturing takes place in China, testing followed the 2012 GEMS determination with test method A.

The span from two to six poles alongside a wide power range points to two different drive tasks: the two-pole 55 kW version at 3,000 rpm for high-speed pumps and compressors, the six-pole 18.5 kW version at 1,000 rpm for slow-running conveyors and agitators; the multi-voltage design up to 690 V allows use across different grid systems without a separate transformer.

When buying used, bearing condition and a checked insulation resistance of the winding, the tightness of the terminal box and shaft lead-through given the partly high protection classes up to IP66, the condition of shaft and key, and a legible nameplate with frame size, pole count and voltage range matter. Spares run through Wonder's distribution.

Frequently asked questions

How much power does the Wonder ZWE180L6 have?

The Wonder ZWE180L6 delivers 18.5 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.
