Answer / mani

We have to interchange either starting winding connection
or running winding connection.But not both.

Answer / tauseef tarique, engineer(e)

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 / raghunandan

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.

Answer / joji joseph

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.

Answer / joseph

inter change the start winding or running winding connections of a motor it will DOR should change

Answer / ahmed

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

Answer / mayank chauhan.

Reverse the connections of either starting wdg. or running wdg., Also by reversing the connections of capacitor we can reverse the direction of 1-phase ind. motor.
