Calculate output power of induction motor
Web%Efficiency of the motor is defined as its rated efficiency and it is ration between output input. Service factor is the ratio of actual maximum power to the rated power mentioned on the plate of the motor. Example # 1: A 230 volt three phase, 1/2 HP induction motor has an efficiency rating of 88% and a power factor of 85%. WebInduction Motor Power Flow. The purpose of a motor, of course, is to convert electrical energy into mechanical energy. The equivalent circuit can be used to visualize and calculate the flow of power through the motor. As shown in Figure 1, electrical power is put into the motor and is converted to heat or mechanical work.
