The Invertek IMP-80K-2 is a three-phase induction motor built by Invertek. The rated output is 0.75 kW. The motor is two-pole, which at 50 Hz gives a synchronous speed of 3,000 rpm. The housing is frame size 80 M in foot-mounted form. The protection class is IP55. The efficiency is 83.5 per cent at full load, 83.4 per cent at 75 per cent load and 80.9 per cent at half load. Mounting arrangements to IEC 60034-7: B3, B14, B34, B5 and B35. The motor is built in China. The data is based on the Australian MEPS registration under standard AS/NZS 1359.5:2004; measured to AS/NZS 1359.102.3:2000. Rated output across the Invertek range ranges from 0.75 to 160 kW; the IMP-80K-2 sits at the bottom of that range with 0.75 kW. Its immediate neighbours are the IMA-802-2 above it with 1.1 kW. 91 Invertek models are on record. The model is listed under Electric motors. 22 verified figures from 1 source are on file.

Invertek – other models: the collective page of MEPS-registered three-phase motors outside the named ranges, frame sizes 80 to 315, 0.75 to 160 kW, 2- to 6-pole

This page gathers the three-phase motors carried in the Australian energy-efficiency register under the Invertek brand, which the register does not assign to a named range. Invertek Drives, headquartered in Welshpool, Wales, is known chiefly as a British manufacturer of variable-frequency drives; the motors listed here are likely matched drives for the company's own inverters, although the dump itself shows no link to specific inverter types. The type designations follow the scheme IM- or IMA- with frame size and pole count, e.g. IM-100L1-4 or IMA-100L-2; the exact distinction between IM and IMA cannot be reliably established from the dump.

The register lists here 91 versions with 0.75 to 160 kW, two- to six-pole, full-load efficiencies from 77.8 to 95.8% and at 75% load from 76.7 to 95.6%. Protection rating splits roughly evenly between plain IP55 and a broader combination reaching IP65/IP66; frame sizes run from 80 to 315 under IEC, manufactured consistently in China. Testing followed mostly AS/NZS 1359.5:2004, a smaller share the 2012 GEMS determinations. For 17 of the 91 motors a High Efficiency Level is documented, spread across the 2005 level and the older 2001 level; the remaining 74 reach no classification.

As a motor programme alongside its core drives business, the page shows that Invertek can offer customers complete drive packages of inverter and matched standard motor rather than supplying only the power electronics; in the variable-speed drive market the company competes with Danfoss, ABB and Yaskawa.

When buying used or replacing, 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; anyone wanting to run the motor from an inverter should also check the insulation class and suitability for pulse-width modulation. Spares and support run through the Invertek sales network.

Frequently asked questions

How much power does the Invertek IMP-80K-2 have?

The Invertek IMP-80K-2 delivers 0.8 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.
