Today on site, I bought in a couple of 12hp pumps, motors wired in star. They spun in reverse when I hooked them up to the generator fed supply, despite my knowing the configuration was correct and already tested in my workshop.
3 windings and a star point. With the phase rotation you had, configuration was incorrect for the rotor direction you wanted. A motor spinning the other way to what you want is still technically correct electrically......just not the way you wanted it . What he did Switching any 2 phases was the right thing to do.
