What is IE1 in 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) IE4 (Super Premium Efficiency)
Are TECO motors any good?
Superior quality motors TECO Electric Motors are regarded as one of the leading brands available on the market and are regularly specified and preferred amongst equipment manufacturers, constructors, engineering companies and major end-users alike.
What is IE 2 motor?
IE2 Motors (High Efficiency) The IE2 motors lie in the IE2 class of the international efficiency standard. The output of the IE2 motors is 0.75kW to 355kW. The poles for the IE2 motors are 2, 4, 6. The speed range of the IE2 motors is from 1000rpm to 3600rpm. The rpm frequency for IE2 motors is 50Hz or 60Hz.
How electric motors are rated?
Electrical motors are rated in horsepower or watt Power is in general rated in watt (W) or horsepower (hp). The old imperial unit horsepower is equal to 746 watts (0.745 kW) or 33000 lb ft per minute (or 550 lb ft per second).
What is IE1 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 IE1 & IE2 of motor?
IE is “International Efficiency” with class 1, 2 & 3 i.e. IE1 & IE2 & IE3. Over 70% of all electrical energy consumed in industries is used by the motors, hence improving the efficiency of electric motors can save energy as well as operating cost, which is more than its purchase cost.
Where are TECO motors made?
TECO formally changed the company name to TECO-Westinghouse Motors (Canada) Inc., which handles all the Canadian marketing, sales, and product services for TECO and TECO-Westinghouse branded motors manufactured in Taiwan, China and Malaysia.
Where are TECO air conditioners made?
The Teco air conditioner division utilises production facilities in Taiwan and China.
What is IE1 in chemistry?
IE1 is the ionisation enthalpy 1 which is the required energy to remove the outer most electron from an atom.
Why is IE2 greater than IE1?
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 .
Which is better IE1 or IE2 motor efficiency?
IE1 efficiency is 77.2% IE2 efficiency is 82.8% IE3 efficiency is 85.3% For bigger ones, 2 pole 200 kW operating at 50 Hz:
What are international efficiency ( ie ) standards for motors?
For these motors, the IEC 60034-30-1 standard defines four efficiency classes: The actual efficiency values required to meet each class (IE1, IE2, etc.) depend on the motor’s operating frequency, number of poles, and rated output, as shown in the example below.
Which is the under construction motor IE4 or IE5?
IE5 motor is the under-construction motor and which would be 20% lesser losses than the IE4 motors. Currently, the manufacturers are not allowed to develop IE5 motors. IE1, IE2, IE3, IE4 Efficiency Table: IE1, IE2, IE3, IE4 Efficiency Class Table
What is the difference between IE1 and eff2?
IE1 is nothing but an International Efficiency class 1. It is standard efficiency class as per the testing method of IEC 60034-30:2008. IE1 efficiency class is equal to the EFF2 class. The loss of the IE1 motors is 16% (including copper losses, iron loss) higher than the IE2 motors.
