What are IE standards?

What are IE standards?

Internationally, there is a standard which stipulates the energy efficiency of low voltage AC motors, namely the International Efficiency (IE). The purpose of which is to promote higher energy efficiency to reduce the energy consumption and the energy cost of low voltage AC motors.

What is IE 1 and IE2?

Efficiency classes IE1 (Standard Efficiency) IE2 (High Efficiency) IE3 (Premium Efficiency) IE4 (Super Premium Efficiency)

What is insulation class of motor?

NEMA motor insulation classes describes the ability of motor insulation in the windings to handle heat. There are four insulation classes in use namely: A, B, F, and H. a 10° C increase in the operating temperature above the allowed maximum can cut the motor’s insulation life expectancy in half.

What is efficiency class IE3?

Electric motors that are identified with the new IE code for energy efficiency classes must also be measured with the new measurement procedure as per IEC 60034-2-1:2007….Overview of energy efficiency classes for electrical drives.

What is motor insulation class F?

The F refers to the insulation class for the windings, while the B refers to an 80°C rise (the maximum temperature rise for Class B is 80°C). This type of notation is becoming more widespread because many motors use Class F insulation, and there is a reason for that.

What is iec600341?

IEC 60034-1:2017 is applicable to all rotating electrical machines except those covered by other IEC standards, for example, IEC 60349. Machines within the scope of this document may also be subject to superseding, modifying or additional requirements in other standards, for example, IEC 60079 and IEC 60092.

What is IE2 and IE3?

The IE Efficiency classes defined as: IE1-Standard Efficiency (Comparable to EFF2) IE2-High Efficiency (Comparable to EFF1) IE3 – Premium Efficiency.

What is the difference between IE2 and IE3?

IE3=IP55, which improves the ability of the motor to dust and waterproof. Efficiency:IE3 average value is 91.5\%, IE2 average value is 87\%. While high efficiency motors have higher efficiency and highly improved the power factor, and make all system saving energy.

What are insulation classes?

There are basically four classes of insulation – A, B, F and H – class F being the most commonly used. These insulation classes were established to meet motor temperature requirements found in industrial applications.

What is H class insulation?

Class H insulation consists of materials such as silicone elastomer and combinations of materials such as mica, glass fibre, asbestos etc., with suitable bonding, impregnating or coating substances such as appropriate silicone resins.

What is IE2 IE3?

What does class B insulation mean?

Temperature Rise Letter The F refers to the insulation class for the windings, while the B refers to an 80°C rise (the maximum temperature rise for Class B is 80°C). This type of notation is becoming more widespread because many motors use Class F insulation, and there is a reason for that.
