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?

According to Ohms's Law, yes.

Current = Volatge / Resistance, resistance is a constant given the same
motor.
