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.

I have made a 3 phase thyristor full bridge rectifier. But at the moment it is working only for the half bridge operation. Both the half bridges are on operation separately but when i put it into full bridge operation the oscilloscope output is zero. I rechecked that the pulses are correct for each thyristor. what could be the possible reason for this?
