For changing the direction of rotation of a single phase
induction motor u reverse either starting winding
connection or running winding (but do not change both
winding connection otherwise it will rotate in the same
direction). For this you can simple reverse the connection
of capacitor.

For three phase motor interchange the connection of any two
phase.
