How can the direction of a three phase induction motor be reserved..

THe direction of 3 phase induction motor can be reversed by
interchanging the connections i.e. if motor is connected to
3 phase as RYB now by connecting motor in RBY will result
in reversal of direction of motor as the direction of flux
is reversed by changing the connections
