Hi to you all!
When I was in highschool in the electricity shop tall us the rotation of an AC motor cant be reversed.
Today we gave mainance to an AC 110-220V motor and in the plate has the legend; for changue rotation changue black wire to blue.
Of course nothing to do with changing the color of the conductor. Just their position in the electrical joints.
Latter on we have to changue rotation.
And I'm guess whath is the theory behind this?
From the rotation part... I guess the 110-220 has to do with the resistance of windings .
Thanks.
