Atomberg Fan Replacement

[Mario Roby]

Thenone rainy day after we had returned home from shopping we discovered the fan to be intact but it had stopped working. Another complaint raised and in 2 days a service personnel came home and replaced the whole circuit board with a brand new PCB. The new PCB looked way better than the old one. The service technician said it might have been damaged during the thunderstorm. That replacement too was free. Kudos to Atomberg for considering after-sales service so seriously.

I used this slightly modified version of the example code. This prints the hex code and the protocol used. The protocol is an enumerated list that can be seen in the IRremote.h file. This is what mine looks like:

You have to check if the Atomberg devices have been added to the Harmony database. Otherwise, the next thing to do is use the codes in this blog to make your phone generate the IR signals (assuming it has an IR blaster) which can be used to program the Harmony remote. You can use this app for the same. ( -remote.github.io/).

Hi i have atomberg fan with remote control i am using IR blaster to operate. Unfortunately it works only to power on and off. Is there any way I can add remote control to the ir blaster, the ir blaster what i am using is tuya brand.

This is probably not the product you are referring to, as it does not have a ESP chip. That said, it might give you some ideas. I am very impressed by this groups work making Tuya device 100% local, check out their github as well as the write ups on this forum. Good hunting!

I heavily suggest to go the libretuya way instead. Not only they have a working esphome port already but they also plan to upstream the work to esphome

@orange-assistant both groups are doing excellent work and should be supported. As well as the work by tuya-cloudcutter. The Holy Grail is to have the ability to do a OTA firmware replacement with Tasmota, ESPHome or Arduino framework clone. These three groups and others are making fine progress.

While for both the source code is available only one of them actively upstreams (or mainlines) their code. This has various advantages for users and programmers. First obvious one is that if stuff gets integrated in other software it can be easily be updated (the opposite would be just to cherry pick code snippets which are a pain to maintain/update).

IMHO is to support and push software which does active upstreaming. Libretuya looks like to be one of thoose as it aims for nothing else as platformio which on the other hand is the base for many projects like esphome and tasmota(?).

I am really not trying to disagree with you here, but just inject the timing importance of the work being done here. Which IMHO tops for now the idea of upstreaming for the term. If this door is closed by the vendor, that sux!

This BLDC (Brushless Direct Current) Fan was brought to me by a regular Electrician customer stating that lightning blew the board and wanted me to check up whether it can be revived or replaced with a new board.

The burnt IC was DRV10983 12- to 24-V, Three-Phase, Sensor-less BLDC Motor Driver. Though I tried to remove the IC using my Hot SMD Remover setting at its maximum temperature, adjusting the air blow, the IC did not budge. I removed the three caps at the bottom and even tried a hotplate, but in vain. The metal body of the IC had bonded with the thick copper layer of the PCB.

Moreover, looking at the condition removing it was also a most probable waste of efforts. So, I requested for a new board through my techie friends Whatsup group and one of my close friends responded and arranged for an original new board which was an exact replacement.

Fixing the board was easy. The Yellow, Blue and Red wire from the coils should be connected according to the marking on the board and should not be interchanged. What I understood from my friend is that the fan has three phase-winding with the other end joined. Pulses are pumped by the IC in succession to make an electromagnetic force which moves the rotor. Observing the colour code while connecting is very important. The coils show only a few ohms (around 2.5 to 3) between. The output from the SMPS circuit is 24V, which can be measured without connecting the load. I hung the fan on a plastic stool, which had a hole in the middle.

I inserted the long rod into it and put a screw driver in the slot to hold it in place. Then applied power, upon which the LED lit and it just jerked, indicating that the board was working. Then removed the fan and fit the top cover, which has half of the metal housing for the magnetic effect. Then fit the fan again in the stool and allowed it to run for more than one hour, while using the remote for various speeds, on/off functions etc. It worked very well, bringing satisfaction to get collected as usual!

Goof Fix! Sir

five-star rating devices are made for low electricity consumption & power saving,We already buying these devices consuming almost 3-times higher price than normal working Design, but if anything goes wrong whole saving is consumed for the repair. this concept does not make any sense for saving anything.

Most motors and generators like used in wind generators are mainly three phased now. I made a 3 phase generator to be able to test those motors with the electronic components in this project that I also 3D printed:

Great effort Parasuraman!

Masking the chip off with kapton tape (or aluminum foil helps protect surrounding components so you can be free (or free-er) to heat the target chip up longer. There is also a low temp melt solder that can be applied to help transfer heat more effectively into those big chips and break them loose.

BLDC fan motor works on direct current, consisting of permanent magnets instead of electromagnets (in conventional fan motors). The permanent magnet makes BLDC fan motors lose less energy than conventional fans. BLDC motor converts the alternate current into direct current, allowing fans to work smoothly even at power fluctuations and low voltage. -dc-fans

I also got 3 fans burned in lighting.. atomberg doesn't have the replacement board since it's their 1st model in 2016.the current boards are different..can it be repaired or a compatible board be fixed

In the bustling market of consumer electronics, a narrative of innovation and determination unfolds with Atomberg Technologies. Founded by visionary engineers Manoj Meena and Shibam Das, alumni of IIT Bombay, Atomberg Technology is not just a company; it's a phenomenon that has redefined what we expect from something as ubiquitous as the ceiling fan. Their story is a testament to how a simple idea, rooted in addressing a basic need, can spiral into a revolutionary product changing millions of lives.

The inception of Atomberg was sparked by a personal struggle faced by Manoj Meena in his hometown, where electricity shortages were more the rule than the exception. This adversity ignited a passion for energy conservation, leading to the birth of a groundbreaking idea: the replacement of inefficient induction motors in ceiling fans with Brushless DC motors. This innovation not only promised a drastic reduction in energy consumption but also set the stage for a revolution in the Indian ceiling fan market.

Like any disruptive startup, Atomberg's journey was fraught with hurdles. Initially, the higher price point of their feature-rich fans made inroads into traditional sales channels challenging. However, by targeting B2B clients such as hospitals and schools and emphasising the energy-saving benefits, Atomberg began to gain traction. Major clients like Tata and Indian Railways were soon to follow, endorsing the brand's value proposition.

In 2016, Atomberg ventured into the online marketplace, a move met with challenges like a lack of brand recognition and concerns over after-sales service. Undeterred, the company doubled down on product functionality and customer trust, instituting a 'no questions asked return and refund' policy. This strategy paid dividends, quickly establishing Atomberg as a top-rated seller on major platforms like Amazon and Flipkart.
