Invertek Other models

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.
