What is IE2 motor efficiency?

What is IE2 motor efficiency?

The IE Efficiency classes defined as: IE1-Standard Efficiency (Comparable to EFF2) IE2-High Efficiency (Comparable to EFF1) IE3 – Premium Efficiency. Havells is the first in India to introduce complete range of IE2, IE3 Efficiency Motors.

Which is better IE2 or IE3?

Efficiency:IE3 average value is 91.5%, IE2 average value is 87%. Note: The above all are calculated value of electromagnetism. From the above data, we can see that: one 7.5KW motor which has Grade 1 energy efficiency can save 892 degree than Grade 2.

What is IE2 in induction motor?

In the IEC 60034-30-1 the following efficiency classes are defined for induction motors (IE = International Efficiency : IE1 (Standard Efficiency) IE2 (High Efficiency) IE3 (Premium Efficiency)

What is the efficiency of IE1 motor?

The IE1 motors lie in the IE1 class of the international efficiency standard. The output of the IE1 motors is 0.75kW to 355kW. The poles for the IE1 motors are 2, 4, 6, 8, 10 and 12. The speed range of the IE1 motors is from 500rpm to 3600rpm.

What is IE4 efficiency?

IE4 represents the highest energy efficiency whilst IE1 represents the least energy efficiency. In other words, the higher the class number, the higher the motor efficiency. IE5 is to be incorporated in the next edition of IEC 60034-30-1, with a goal to obtain an energy loss reduction of 20% relative to IE4.

What is the relation between IE1 and IE2?

IE1 is normal class. IE2 is Energy Effecient class of Motors.

Why is IE2 greater than IE1?

Second ionization enthalpy is more than first ionization enthalpy because it requires more energy to remove an electron from a unipositive ion to make it a dipositive ion. Penetration of orbitals in to inner space.

What does IE2 mean chemistry?

Explanation: The second ionization energy ( IE2 ) is the energy required to remove an electron from a 1+ cation in the gaseous state. X+(g)→X2-(g)+e- Just like the first ionization energy, IE2 is affected by size, effective nuclear charge, and electron configuration.

What is IE1 and IE2 why IE2 is greater than IE1?

IE2 is greater than IE1 because after losing an electron, size of atom decreases and the gripping force on the remaining electrons gets stronger and it needs higher energy to remove the second electron. IE decreases when size of atom increases and vice-versa. IE is higher for cations because of smaller atomic radius.

Why is IE1 always less than IE2?

ionisation energy or ionisation enthalpy is the enrgy required to remove the most loosely bound electron from an isolated gaseous atom . and IE1 , IE2 , these are the removal of first as well as second electron from an atom . the second ionisation energy is always more than that of first ionisation energy .
