    Hello guys.

    I want a help in understanding how electromechanical meters work. To be specific I want to know what's the circuit that rotates the disk with kilowatt readings. schemes would be great.

    Thanks.

    its a simple induction motor, the house current goes through coils, inducing current of a different phase in the aluminum disk.

    yes, this is the basic idea. But, I want to know more about the circuitry.

    yes I have. But I didn't find any circuit diagrams for that.

    There are no electronic components in the meter. It's a metal disk that is rotated by a magnetic field and turns the dials through gears.

    That was fantastic. Except that the meter that I'm looking for is a 3 phase meter....What are the differences??

    Think of a coil meter as a motor.
