Re: 110v vs 240 v

In series the same current must flow through both does it not?

I don't know how the motor is wired inside, I only know how to switch it from 120 to 240, or I did when I switched it. The picture and instructions are inside.

Because it's alternating current. In 110 V the power line (L1) goes to one end of each winding, The neutral line (L2) goes to the other end of each winding. There is 110V at each winding and each draws 6 amps for a total of 12 amps at L1.

In 220 you have a line (L1) at one end of one winding and one line (L2) at one end of the other winding and the other two winding ends are joined together. The windings draw 6 amps each and you have 6 amps at L1 and 6 amps at L2. You are still drawing a total of 12 amps.

Because it's AC, the current alternates at L1 from power to neutral at 60 times per second. L2 is out of phase with L1 and alternates opposite. When L1 is power, L2 is neutral and vise versa.
