What selector motor are you meaning?
80%
EFF1 is a high efficiency motor. EFF2 is a standard efficiency motor.
Motor bird is not a compound word.
Yes this is what we call efficiency of the motor. We give 100 but the motor in turn gives 40, so its efficiency is 40%
Its flattened
Motor size depends upon number of factore. 1- flow of pupm 2- required head 3- efficiency of pupm used 4- efficiency of electric motor used The formula is H.P required= Q.H\ 3960. Pump efficiency. Motor efficiency where Q= GPM H= Ft Efficiency= In fraction( 70 % = 0.7) Engr. Usman Khalid +923336901945 usman.engr87@gmail.com
It is maximum at about 75% to 100% of the motor rated load. Efficiency is maximum at unity power factor , when R=X and when variable losses Is equal to constant losses at rated load.
I measure the efficiency of an internal combustian engine by doing (bhp)/((displacement)*(rpm))
Motor efficiency depends on the motor size and how much it is loaded. You get the best efficiency above 75% of the rated load for that motor. Note the table below: Horsepower Standard Premium Efficiency Efficiency% Efficiency% 1 --- 78.0 --- 82.5 2 --- 78.5 --- 84.0 5 --- 84.0 --- 89.6 10 --- 84.0 --- 91.1 15 --- 87.5 --- 91.7 25 --- 90.2 --- 93.0 50 --- 91.7 --- 94.1 100 --- 91.7 --- 95.0 250 --- 94.1 --- 95.8
You can calculate the quantity of energy that a motor turns into heat with either one of these equations: Heat energy = ( 1 - efficiency of the motor) x (energy input to the motor) or Heat energy = ( 1 - efficiency of the motor) x (power input to the motor) x (running time)
ratio of energy output to energy input.
