DESIGN INFORMATION:
1. What is the power absorbed by a Motor load?
Power absorbed is the input power drawn by the motor. It should be noted that a motor’s rated kW or name plate rating is the output rating of the motor (also known as the shaft power).
When we are calculating the total load requirements of a system, we have to always use absorbed power, which is the actual power drawn by the motor.
Power absorbed= input power=kW rating/ efficiency
It is also represented as “ P1” in pump data sheets.
Also note that the Input current drawn by a motor= kW/(1.732 *V* pF)
