Efficiency Class Ie3 Motors Plastcompany The standard defines four ie (international efficiency) efficiency classes for single speed electric motors that are rated according to iec 60034 1 or iec 60079 0 (explosive atmospheres) and designed for operation on sinusoidal voltage. Ie3 motors strike a balance between efficiency and cost, making them a preferred choice for industrial use. ie4 motors further reduce energy consumption, offering superior efficiency for demanding work.
Ie3 Efficiency Class Motor If the motor efficiency is 86%, it will be considered as ie1 class as well as the motor efficiency is 88.7 and above, it will be considered as ie2 class and for the efficiency of 90.4 and 92.6 are ie3 and ie4 rating. Electric motors are categorised into efficiency classes: ie1, ie2, ie3, and ie4, each representing a step up in energy efficiency. ie1 motors are the least efficient, while ie4 motors are the most efficient. Iec 60034 motor efficiency guide for africa and middle east projects. covers ie2, ie3, ie4 and ie5 classifications, regulatory expectations, and application guidance. Switching from ie2 → ie3 typically saves 5–15% energy, and ie3 → ie4 saves even more. that means buying the “more expensive” motor often pays for itself within 6–18 months.

As per new standard iec 60034 30 1 published in march 2014, four level of motor efficiency are defined for three phase induction motors. the updated standard iec 60034 30 1 includes ie1, ie2, ie3 and the fourth efficiency level ie4. Ie 2 motors are approximately 92 3% efficient, while ie3 motors are approximately 93.6% efficient. these motors can run continuously on warehouse conveyors for up to 3,500 hours a year. Here is an extract of the statutory minimum efficiency levels: from 1 june. 2021, three phase motors from 0.75 kw to 1000 kw must be at least ie3 efficient. similarly, electric motors from 0.12 kw to 0.55 kw must be manufactured to at least efficiency class ie2. Ie3 motors typically improve efficiency over ie2 by reducing copper and iron losses simultaneously: more copper in the slots (heavier winding), better electrical steel grades, and optimized geometry.
