Re: How to determine with DMM which one is the start winding & which one is run windi
a centrifugal switch is operated by rotational force.
it will be in closed position at start of rotation and until a set speed is reached.
beyond which , it will open.
the centrifugal switch is connected to aux wndg circuit.
So that , aux wndg will be connected at satart. when motor is reaching the full speed it will be cut from supply by centrifugal switch.
you can refer the diagram , attached in the earlier message.
