How we can change the rotation of ceiling fan? Is it possible or not? All ceiling fans rotate in a clockwise direction. How we can rotate a ceiling fan in to anti-clockwise direction? ( all ceiling fans are single phase motor ).

Most ceiling fans have a reverse switch on the side of the motor housing, so they can operate in either direction.

Read the owners manual.

Most ceiling fans are reversible, there's a switch located on fan in visible spot, if so....

just change the wire connection of capacitor i.e the wire which comes from the main source to capacitor, just change the wire position from capacitor +ve point to -ve point or if wire is alreday attached to -ve terminal of capacitor than change it from -ve to +ve terminal of capacitor

dear you say you have two wires L AND N L is +ve and N is -ve

ie L means phase and N means neutral

now listen in your celling fan, your main two wires L and N are coming from main source and then either L or N wire goes directly to the motor windings wire and it is directly connected to the winding say this wire N wire , now the other wire say L is coming to capaciter terminal... now simple work which you have to done is that you have to change the wire from capacitor one terminal to another....be carefull do not change any more just change the wire L from capacitor one terminal to another.....

You can quickly tell an electric motor novice. They think that the type of motor they have is defined by the function it performs. They have no idea if there motor is a synchronous induction, universal, series or parallel brushed, stepping, DC brushless, hysteresis, linear or even a piezo motor. I've yet to find a motor that couldn't be rewired to rotate in either direction but I'm certain that a universal motor exists that the stator and rotor windings cannot be separated.

Import one from the southern hemisphere. They do everything backwards down there.

That's not true. The fans still go the same way, it's just that we're looking at them from a different angle!

Lots of great and sometimes funny answers here, I love you guys.

I would say that one would need to know the motor type to be able to reverse it and to be honest, I personally do not know the type.

There are some good infos on these weblinks that may help further:-

For the fan to reverse the direction of rotation and still give discharge , the blades design has to be changed.

Giggle.

I'm certain that the goal of reversing the motor rotation was to reverse the air flow.

Not true, the change in air direction is required as a summer versus winter thing.

Read the link I posted....

Your country is not known, but in Americas and UK the ceiling fans has 2 or 3 clutch switches operated by a cord hanging down.

1 for light on/off

2. for fan on/off and speed

3rd one for speed Fwd /Rev

Now technically:

For a fan without direction change switch

fan has 3 connections [keep the speed connections alone]:

1. Common [normally connected to Neutral ]

2 and 3 are across the [Starting] capacitor.

Here any one has 2 wires connected, 1 from winding and the other from mains

[may be through on-off switch].

If you take this wire to the other end of capacitor it will reverse the direction.

Theoratically: Chang of the phase produced through capacitor to lead or lag the mains phase.

For a fan with direction change switch

Here yuo will see 2wires connected to capacitor ends.

one from each end goes to windings and the others going to Direction change switch.
