Just remember those "7.5amps each" are not additive. (Robatoy,
don't look ) It's the same amps in each leg - one's coming to
the motor, the other's returning it from whence it came. Just like
120v, one line brings the amps in, the other line takes it back.

Not additive? Now I am back to the beginning of understanding. Isn't
the motor running at 15amps on either 120v or 240v?

No. If it draws 15 amps on 120 it should draw 7.5 amps on 240. On
120 15 amps come in the hot and go out the neutral, on 240 7.5 amps
go in the hot and go out the other hot.- Hide quoted text -

OK, so if I could run the motor on 60volts it would draw 30amps?

If it's designed to run on 60 volts with the same power output as it gives
on 120, yes.
