What is difference between IE3 and IE4 motors?
The initial investment cost of the IE4-motor is higher comparing to the IE3-motor. However, the payback period of the IE4-motor is only 2.9 years and much shorter than that of the IE3 motor. Therefore, even with the higher initial investment cost, the IE4-motor is significantly more profitable.
What is difference between IE2 and IE3 motors?
What is IE explain the factors affecting IE?
FACTORS AFFECTING IE. 1- atomic radius , 2- nuclear charge 3- orbital penetration. 4- sheilding or screening effect 5- electron pairing within a subshell . HOPE IT CLEARS NOW.
What is IE efficiency class?
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.
How do you calculate the power of a 3 phase motor?
How do I calculate a 3-phase motor horsepower? You can use this equation HP = amperage × motor voltage × power factor × efficiency × 1.73205 / 746 to calculate the power rating of a 3-phase motor in horsepower.
Why is there steep rise in IE from carbon to nitrogen?
Carbon has a higher electron affinity than nitrogen because if nitrogen was to gain another electron, the electron would experience electron repulsion in one of the orbitals, meaning that more energy is required.
