HOW TO DISCOVER FAULTS IN ELECTRIC FAN

Electric fan is one of the major electrical appliances used in countries with hot weather conditions like Nigeria. Though common in the area, it is possible that every home across the globe have electric fan, the usability relies on the weather conditions in each country.

The electric fan manufacturers had done a lot to improve the technology by coming up with several designs to suit the need of the consumers over the years. Starting from the popular industrial fan expellers to domestic and personal fans. One of the ways they achieved that was through the making of electric fan for different purposes like; the standing fan, table fan, wall fan, ceiling fan, floor fan and window fan called expeller. These fans have their various uses, designs and sizes meant for a particular need. But basically they all operate with the same principle.

The basic principle electric fan operates with is that of the electromagnetic induction. If two magnets are brought together and current is meant to pass through one it will create a rotation effect and that is the principle all electric motors were made and that is the same motor all electric fan use. Details of electromagnetic inductions and how electric fan engines use its principle for operation can be discovered later in this blog.

Therefore, to know the problems of electric fan; one must understand the basic principle of electromagnetic inductions. There are several faults electric fan can develop which do not relate to its engine, such includes; blade problems, cracking of covers, and the base or support damage, etc. so finding faults in electric fan require the individual to know how to identify basic causes of the problems of electric fan first, which had been written in our previous posts.

We had explained basic causes of electric fanfan problems and their solutions in our previous post as said earlier. So, it important to go through the post after reading this one. There are several ways one can identify faults in electric fan and that can be done either through direct inspection or through a device. For faults relating to the motor coil, using an ohmmeter to check for discontinuity can be a better option.

To check for the discontinuity in the coil of electric fan, obtain the two or more edges of the coil and start checking edges to edges to detect where the coil has discontinuity which can be the major source of the fan’s engine problem. Other categories of faults can be obtained through inspection or physical observations.

However, it is common for one to give up easily while trying to ratify faults in electric fan coil while using the method mentioned above. The reason is because, it is tedious and requires lots of patience to detect the actual cause of the problem in the coil. If one should visit the technicians that usually repair electric fan you would observe that it is the same technique they are using to detect serious faults in the fan’s engine coil. Other methods may include running a live current through the coil and using a voltmeter to note where the voltage stopped flowing in the coil but the method is very risky and unsafe because it do lead to electric shocks while doing it.

  2. “Whats up! I just want to give a huge thumbs up for the good info you have got right here on this post. I will be coming again to your weblog for extra soon.”

  3. “I have seen lots of useful things on your internet site about personal computers. However, I have the opinion that notebook computers are still not quite powerful sufficiently to be a good choice if you usually do tasks that require many power, such as video modifying. But for net surfing, word processing, and most other prevalent computer work they are just fine, provided you can’t mind small screen size. Many thanks sharing your notions.”

  4. “I love your blog.. very nice colors & theme. Did you make this website yourself or did you hire someone to do it for you? Plz respond as I’m looking to construct my own blog and would like to find out where u got this from. kudos”

  5. “You really make it seem so easy with your presentation but I find this topic to be really something that I think I would never understand. It seems too complex and very broad for me. I am looking forward for your next post, I will try to get the hang of it!”

  6. “Good – I should certainly pronounce, impressed with your website. I had no trouble navigating through all tabs as well as related info ended up being truly simple to do to access. I recently found what I hoped for before you know it in the least. Reasonably unusual. Is likely to appreciate it for those who add forums or anything, site theme. a tones way for your client to communicate. Nice task..”

  7. “Thanks for enabling me to get new strategies about computers. I also contain the belief that certain of the best ways to keep your laptop computer in prime condition is by using a hard plastic material case, or shell, which fits over the top of the computer. These types of protective gear usually are model specific since they are manufactured to fit perfectly on the natural casing. You can buy all of them directly from the vendor, or via third party sources if they are for your mobile computer, however only a few laptop can have a shell on the market. Yet again, thanks for your tips.”
