IE4 electric motors represent the Super Premium efficiency class under IEC 60034-30-1 and run with markedly lower losses than lower-class motors of the same power. To understand IE4 pricing you should read the lifetime energy balance, not just the purchase price.

What Sets the IE4 Price

IE4 motors use more copper winding, high-grade silicon steel and precise workmanship to cut losses, which lifts the list price above IE2-IE3. Price is also set by power (kW), speed (2/4/6 pole) and the choice of cast iron or aluminium frame. Higher power and lower speed move the band upward.

Payback Through Energy Savings

The upfront premium of an IE4 motor returns quickly in continuously running applications. Because higher efficiency means less waste heat every hour, annual electricity use falls and the difference is usually covered by savings within a few years. That makes IE4 a sound choice for multi-shift plants.

Where IE4 Fits Best

For equipment running limited hours a day IE3 may be enough, while for loads that turn all day such as pumps, fans and compressors the IE4 energy advantage becomes clear. The more operating hours, the faster the IE4 price premium is amortized.
