Hi all
ok...i was asked to wire a motor for a fan today....3 phase motor...it had its mains lead attached pre wired.
when we finished wiring the supply and starter i was surprised to see it was spinning in the wrong direction.......well not that surprised ...the owner got it from ebay from a bankruptcy sale..!
so...no bother i thought....and when to swap 2 phases over (as done many times before)
when i opened the terminal cover i saw that the red and yellow (old colours) were round the wrong way....
so swapped them back to the standard r , y , b ...job done...
but the motor continued to run the same direction......???
why...?
how can i change the direction of rotation..?
cheers
