Operate principle

Due to different phase, different spatial positiuon and produced by two fixed electromagnet and current induced in the rotating element(round plate) interaction, to rotate the rotating element. And due to magnet steel braking action to accelerate the round plate to reach a certain speed, and also due to magnetic flow and voltage, current are in proportion, rotation of disck is transmitted to the meter by worm, and the number of the meter is shown to be the actual power consumption of the circuit.
