One new circuit for is invented by Mohamedthambi, student of MKU University for Electronic Fan Regulator which is cheap and best. In the current available fan regulator, the barroter is used to the voltages at various level. But in our product is the PCB is used to drop the voltages at various level.
1.fig B shows the full view of the product and the external side of the product.
2.figA shows the full connection diagram of the product 3figC shows the PCB without resistance 1st we have to take PCB as shown in figA then we put the resistance and solder in PCB holes as shown in fig A Now we connect the PCB ends with rotator switch as shown in figA.
Now we connect the rotator switch with as 230v supply if we vary the rotator switch we can get the five different speed of fan The Resistance network is used to drop the voltages in five-level. The terminal 1 no resistance is connected to the fan so we can get the full speed of the fan. At terminal 2 13ohms resistance is connected to the fan so the speed of the fan is reduced due to resistance connected to the fan the speed is less than that of terminal 1. At terminal 3 26ohms is connected to the fan the speed of the fan is reduced than the previous level. Hence we get five various levels by rotating rotator switch we can get the different speed of the fan. In the available fan regulator, the Barrotor is very costlier than PCB with resistance
What is the idea?
The ideas is to design a new circuit to reduce the cost and increase the performance.
What does it do?
It regulates the speed of the electric fan motor by dropping a.c. voltages in a different level.
How does it work?
It is working by ohms law and circuit theory principles.
Have ever seen anything similar?
Yes, I have seen available electrical fan regulator but the circuit is different in available.
What makes this idea unique?
Low cost, low care and a lot of advantages
Advantages of this new Electronic Fan Regulator
cheap cost, low care, low power loss, low heat loss, Good
Performance Estimation required
- 28 RESISTANCE
- ONE PCB
- ROTATOR SWITCH
- PLASTIC CABINET
In the Indian market, One resistance price is 0.15, 28 resistance = 4.20 One PCB 5.00 One rotator switch 8.00 One plastic cabinet 5.00 Total 22.20. That’s all.
