The EMT Y2 200L4 comes from the Y2 series. The rated output is 30 kW. The motor is four-pole, which at 50 Hz gives a synchronous speed of 1,500 rpm. The rated voltage is 400 V. The housing is frame size 200 L in foot-mounted form. The protection class is IP55 and IP56. The efficiency is 93 per cent at full load, 93.1 per cent at 75 per cent load and 92.4 per cent at half load. The motor weighs 235 kg. At full load it delivers 193.8 Nm. Mounting arrangements to IEC 60034-7: B3, B5, B14, B34, B35, V1, V3 and V5. The motor is built in China. The figures come from the Australian MEPS register under the GEMS Determination 2019; measured to IEC 61972. The Y2 series covers 42 models. Rated output within it ranges from 0.75 to 75 kW; the Y2 200L4 sits in the lower part of that range with 30 kW. Its immediate neighbours are the Y2 HE 200L26 below it with 22 kW and the Y2 200LX2 above it with 37 kW. 274 EMT models across 5 series are on record.

EMT Y2 – other models: the collective page of MEPS-registered three-phase motors built to the Chinese Y2 standard-motor scheme outside the named ranges, frame sizes 80 to 280, 0.75 to 75 kW, 2- to 8-pole

This page gathers the three-phase motors from the supplier EMT that the Australian energy-efficiency register could not assign to a named range. The model designations consistently follow the Y2 range scheme – Y2 200L4, Y2 AHE 112M2, Y2 HE 100L14 – a standard-motor design for three-phase induction motors widespread in China that replaced the older Y range. The AHE and HE suffixes within the model designation mark separate range variants; their exact technical meaning cannot be reliably reconstructed from the dump alone.

The register lists here 42 versions with 0.75 to 75 kW, two- to eight-pole, full-load efficiencies from 77.5 to 95% and at 75% load from 76.6 to 95.2%. Frame sizes run from 80 to 280, protection is IP55/IP56 for practically all 42 motors, and the mounting codes are uniformly set to the full B3, B5, B14, B34, B35, V1, V3, V5 set. China alone is recorded as the manufacturing country. Testing mostly followed AS/NZS 1359.5:2004 and the 2019 GEMS determination, with test method B for the large majority; only 5 of the 42 motors reach the 2005 High Efficiency Level, 37 remain unclassified.

The Y2 range is built by numerous Chinese makers in near-identical form and forms the backbone there of value-oriented standard-motor demand for pumps, fans, compressors and conveying plant; EMT appears here as one of the suppliers registering this scheme under its own brand name.

When buying used, what matters is bearing condition and a checked insulation resistance of the winding, the visible build quality of the terminal box and fan cover, the condition of shaft and key, and a legible nameplate with frame size, pole count and, where present, efficiency class; since only a small share of the models carry a High Efficiency classification, inverter suitability should be checked case by case. Spares run through the relevant EMT distribution channel.

Frequently asked questions

How much power does the EMT Y2 200L4 have?

The EMT Y2 200L4 delivers 30 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.
