Question
how can we change the rotating direction of single phase AC 
induction motors?
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
We have to interchange either starting winding connection
or running winding connection.But not both.

# 2
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.

Answer
# 3
as single phase Ac induction motor are not self starting
they need capacitor to introduce phase difference.In
capacitor start and capacitor run motor(all ceiling fans) by
interchanging the leads of either capacitor or running
winding we can change the direction of rotation.

# 5
we can change the direction of single phase induction motor
by interchanging the leads of main winding or starting
winding,but not both.Also by by interchanging the leads of
capacitor, we can change the direction.

# 9
we can reverse the direction of the single phase induction
motor by change the connection of the capacitor or by change
the connection of the running winding
 
Is This Answer Correct ?    7 Yes 7 No

Answer
# 10
I thing if we just reverse the direction of capacitor then it will change the direction of main and starting coil field direction ..... so it will create a opposite directional rotational field then motor will start moving opposite direction
