Answer / a.p.nanjappa

there is no different for the fan,whether itis clockwise or
anticlockwise for table and ceilinf fans. it is just the
design of fan blades.

But it matter for the exhaust fans.

Answer / sukumar

Ceiling fans usually can rotate in either direction. There
is usually a switch on the unit. This allows downflow during
the warm season and upflow during the winter.

The direction of rotation of a table fan is determined by
the shape of the blades. A motor can be made to run in
either direction but to force air to the front of the table
fan, it must rotate in the direction that the blades will
force the air properly.

Answer / shri..

Because stator is fixed & rotar moves in ceiling fan & in
Table fan the stator is fixed & rotar moves.
