STEPS INVOLVED IN THE WINDING OF A FAN The following things must be kept in mind while choosing a fan for winding

Step 1 CHOOSING A FAN we have different types of fans, but we wanted to go for a simplest one. Therefore we consulted a technicians and he guided us that ceiling fan could be the best for winding. So we chose ceiling fan for winding.

STEP 2 LEARNING WINDING Fan winding is such a thing you can't do it of yourselves. It involves some technical, steps where you would work with different electric devices. We consulted a technician in Golimar he taught us fan winding in a very easy way.

STEP 3 HOW WINDING IS DONE? Fan winding needs your technical skills, if you are good at work you can learn winding at least in one week We bought a fan (not in working condition) and the technician opened and told us the basic steps taken for fan winding. the technician opened and repaired the fan by using different tools and at last the fan was running Then we started by our own and it took two days for us to make the fan running.

WINDING STEPS First of all you would find the no of turns in the coil by counting one by one, if you are expert you can guess it. Then you would make coils according to the no of turns. Insulate the in the stator holes with a paper to avoid the contact of coil with the stator. Now place the coils one by one on the stator The process of placing coils is done for both starting and running winding.

After the completion of placing coils you would give connection of coils in both windings. In last you would leave four wires, two of them are connected with each other which is known as common. Then a series board is used for testing the winding, if it is not short circuited a bulb glow and other steps are done on the winding. The starting winding is now connected with capacitor and the running winding is directly connected with main supply. Then the capacitor is connected with main supply.

After the connections the fan is closed and is connected with the main supply. If the fan is moving in anti clockwise direction, then it’s connections are reversed. Anticlockwise movement is useless because it takes air towards the ceiling.

STEP 4 CHOICE OF WIRE FOR WINDING Winding can be done with any conductor, we chose silver because it was not much expensive. You will spend 200 rupees for silver. If you want to do winding with copper you need to spend more than 500 rupees

A FAN CONSISTS OF THE FOLLOWING PARTS PARTSFUNCTIONHANGER It is support of a fan with ceiling. It is stationary part which keeps the fan hanging. STATOR Winding is done on rotor which enables the fan to rotate. ROTOR It is the part of fan which rotates around the rotor.

CAPACITOR The function of capacitor is to give a phase difference, due to which a magnetic field is induced which moves the fan. WINGS Wings of a fan pushes the air around it to all parts of a room.
