Because in celling fan rotor working as a static device &
Stater also working as a Rotating device.
But in case of table fan Rotor working as arotating device
& stator working as a static device.

Answer / tamil

the ceiling fan can usually 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.

In earlier days, the ceiling fan is very heavy and down rod pipe is connected with fan through threaded coupling and chuck nuts. When the ceiling fan starts rotating in anti clock wise direction the armature winding part take jerk in clock wise direction. This clock wise movement helps to prevent the joint getting loosen. Hence the ceiling fan designed to rotate in anti clock wise direction.

Answer / thiagarajan.e

In pedastal fans or table fans the rotar is rotating,in celing fans the winding part is rotating as a rotar

Answer / g.bhardwaj

Basically there is no any difference in rotation, if you
see the both type of fan from blade side both are rotating
in clockwise direction.generally we always in doubt because
in ceiling fan we saw the fan from upper side when it not
connected with ceiling.

Hi, I've just got into my electrical engineering course and I need some help with a question of mine here. During a site visit, we were shown a main LT panel which has switchgears, ammeters and different kinds of relays and the distribution network from that panel. In the main LT panel I've noted down the current readings as Ir - 163A, Iy - 150A and Ib - 147A. The Line to Line voltage is 415 V at 50 Hz and Line to Neutral voltage is 230V at 50 Hz. From the above details, how would I calculate the kVA rating of transformer? The primary side voltage of the transformer is 11 kV and the secondary side voltage is 415V and the frequency is 50 Hz.
