Induction motors are a cornerstone of both domestic and industrial applications, providing versatile power solutions across various settings. Small induction motors find their niche in household appliances, while their larger counterparts are indispensable in heavy industry sectors, driving machinery and powering complex systems. According to the International Efficiency 60034-30-1 standards, these motors are distinguished by their efficiency levels, falling into four distinct categories: IE1, IE2, IE3, and IE4. Each step up in the IE classification represents a leap in performance and energy savings—IE1 motors offer Standard Efficiency, IE2 motors deliver High Efficiency, IE3 motors boast Premium Efficiency, and IE4 motors excel with Super Premium Efficiency. As you move through the series, each subsequent motor class surpasses its predecessor in operational efficiency, marking technological advancements in energy conservation.


IE1 Motors (Standard Efficiency Motors)
IE1 motors are classified under the IE1 category of global efficiency standards, known for their Standard Efficiency. They span an output range from 0.75kW to 355kW, with pole configurations available in 2, 4, 6, 8, 10, and 12. These robust motors operate at speeds from 500rpm to 3600rpm, adaptable to both 50Hz and 60Hz frequencies. The aluminum frame sizes range from 56-200, while for cast iron, they extend from 80-400. Engineered for dependability, they feature a B temperature class, employ IC411 cooling technology, and are crafted with class F insulation. Functioning under Type S duty, they are fortified with protection technologies such as IP55, IP56, IP65, and IP66, all in adherence to international standards IEC 60034-30 and IEC 60034-2-1.


IE2 Motors (High Efficiency)
IE2 motors, representing the IE2 class of the international efficiency standard, are engineered for High Efficiency. They share the same power output range as other classes, from 0.75kW to 355kW, but focus their pole configurations to 2, 4, and 6. With a speed range stretching from 1000rpm to 3600rpm, and accommodating frequencies of 50Hz or 60Hz, they are designed for both versatility and reliable performance. Their aluminum frame sizes are 80-160, and cast iron frames span 80-400. Operating within the B temperature class, they utilize IC411 cooling technology and are insulated with class F materials. Geared for Type S duty, these motors are safeguarded by IP55, IP56, IP65, and IP66 technologies, in compliance with international standards IEC 60034-30 and IEC 60034-2-1.



IE3 Motors (Premium Efficiency)
IE3 motors shine in the IE3 class, celebrated for their Premium Efficiency within the international efficiency standards. Their output ranges from 0.75kW to 355kW, featuring pole options of 2, 4, 6, and 8. They operate within a speed range of 750rpm to 3600rpm, adaptable across 50Hz and 60Hz frequencies, ensuring consistent and optimized performance. Aluminum frame sizes are offered between 80-160, while cast iron frames are available from 80-400. These motors are classified under the B temperature class and adopt advanced cooling technologies like IC411 and IC416, combined with class F insulation. Designed for varied duty types including S1, S2, and S3, they incorporate sophisticated protection mechanisms such as IP55, IP56, IP65, and IP66, adhering to the IEC 60034-1-30 international standards.
