I have a 100 watt extractor fan with metal blades. The fan has built in capacitors. The measured power factor is 1. There must be some advantage of using the capacitors.
I have another fan without capacitors and the power factor is 0.72.
The only possible advantage I can see is that the motor can run faster when the voltage and current are in phase. So if I put in capacitors in the other fan would this speed up the fan? I would like it to run faster.
The reason it is called a power factor must be that the fan motor has more power to move more air and therefore run faster with capacitors.
My question then is if I put in capacitors in my 0.72 power factor fan will the motor run faster? Raising it to a power factor of say 1. If the answer is yes what size capacitor should I use?
I know that the watt reading is the same with or without capacitors. I also know that increasing the watts of the fan motor also increases its power.
