Bldc fan block diagram

Just as the traditional incandescent lamps today are almost replaced with the much efficient LED lampsit's now time for the ceiling fans to become smarter and more efficient. In fact making a BLDC based ceiling fan circuit may be much easier than a capacitor-start type of fan, and could be done by even by an ordinary hobbyist having basic knowledge of electronics.

The BLDC controller specs can be selected as per the available BLDC motor's specs, for example if you find it comfortable procuring a V or V BLDC you could probably go for a controller design having matching specs, such as the following circuit which was posted sometime back in this website. Let's assume we select a 24V 2 Amp BLDC for our ceiling fan, as shown in the following example, make sure it includes sensors with it:.

To control this motor and apply it like a ceiling fan, we can use the 50V driver circuit link as indicated in the previous paragraph, and modify the attached diagram to suit the ceiling fan control parameters, as indicated below:. The diagram looks pretty straightforward, and you just need to connect the parts as displayed in the diagram, using a well designed PCB.

From the above shown BLDC ceiling fan controller circuit, we can understand that the circuit will require a DC power for operating, and this may be fulfilled through any standard SMPS unit, the best example being your laptop charger which can be effectively used for operating the proposed 24V BLDC motorthrough the given controller circuit.

Here the secondary winding ratio could be suitably doubled for getting the required 24V instead of the specified 12V in the design. The main objective of using a BLDC fan is to implement a capacitor less motor or brushless motor where the rotor does not carry any winding, which in turn ensures virtually zero friction and therefore extremely high efficiency compared to the normal capacitor type ceiling fan units.

However it must be noted that motors rated with higher voltage will give higher efficiency for this particular application. This concludes the explanation regarding the making of a simple BLDC ceiling fan circuit, if you have any related doubts let me know through your valuable comments. If you have any circuit related query, you may interact through comments, I'll be most happy to help!

Your email:. Good afternoon. Hi, those are current limiters which are actually not too critical. You can calculate them using Ohms law. Actually u already gave it but parts are not available in market kindly give any online vendor which can deliver to my home. I am interested in innovative ideas and predominantly focusing more on the eco-friendly environment. This article is quite useful to get the basic knowledge on the bldc motor control circuit for ceiling fan.

However, it would be really helpful, if you could enhance the circuit to include the speed control and is there any efficient way to reduce the power consumption. Thanks Manikandan, The 10K pot at top right of the schematic is for controlling speed of the motor. All BLDC drivers will essentially have a feature for the speed control. Hi Dennis, I am not so sure about motor winding, but for transformers I have a few articles published in my website which you can read below:.

This works, but the brushes wear out due to continuous physical operation. The BLDC also has an electronic commutation system.

Brushed motors have a commutator a mechanical rotating switch that periodically reverses the current between the rotor and external circuitry. Brushless DC motors are often small, and range from a few watts to tens of watts.

BLDC motors have been in commercial use since the 60s and the advent of solid state semiconductors, whereas brushed motors have been in use since the origin of motors in the late s. You must be logged in to post a comment.

Our information pack failed to arrive before we left home (but we were in Norway for a week before our itinerary started).

Delighted to find it waiting for us at check in at our Oslo hotel. Any concerns I had were promptly responded to and effectively dealt with by Kolbrun. Delighted with our holiday and by our experiences of Nordic Visitor, and cannot recommend highly enough.

My husband and I went on the 10 day self guided tour of Iceland August 10-19. The books and maps we received help us plan each day and the inss and hostels they picked for us were comfy and perfect.

I am an organizer so getting the information sent to us first was great. I had the tour planned but of course when we got there - there were many things to see. The phone they gave us was a big help with dinner reservations. More than enough mins. When we first arrived we stopped by the office and they went over the map with us and asked us what we wanted to see and then pointed out great items all over the country to stop.

We were able to hit every one of them.

I recommend Nordic Visitor to anyone. They are a great help and so organized. We really appreciated the fine service and flexibility provided by our agent Larus as well as the entire NV staff.

The trip exceeded expectations. Thanks to Alexandra who organised our trip very comprehensively. We were very impressed with all the suggestions and how the map corresponded with the itinerary. We even went to the homemade ice cream seller Alexandra highlighted and had delicious dandelion ice cream. The preparation ensured our holiday went really smoothly. I found the process incredibly easy and informative. The map provided to us with areas of interest was used often and I found all of the documentation to be extremely helpful but easy to process.

Erla accommodated all of our requests - she kept us updated and informed.

I'd like to thank you for organising such a perfect trip in what has to be one of the most beautiful and friendly places I have ever been. I have nothing but positives to bring back from this trip and would highly recommend you to others We were very pleased with our experience using Nordic Visitor. Everything went smoothly, the accomodations were comfortable and clean, and the transportation services excellent. We truly enjoyed our time in Norway seeing your beautiful country.

This was the first time we had used this type of service as we usually do all our travel planning and bookings ourselves. It took the stress and worry out of our trip and so we had a much improved experience of 'drive yourself'.

We found we could relax and enjoy our holiday and we maximised our time in country. We were very happy with all arrangements made by Maria and had NO ISSUES at any venue - suberb. We will definitely do this again in the future as our experience was so positive. Nordic Visitor exceeded our expectations for booking and travel in Iceland. We were well informed prior to even going on our trip about what to expect and how to plan for our travels. We were encouraged to ask questions about any concerns that we had, and we were given very timely responses in return.
